2004 ASME Code Edition Synopsis The 2004 Edition of the ASME Boiler and Pressure Vessel Code was published on July 1, 2004. The revisions/additions/errata published in these addenda represent items voted and approved by the ASME B&PV Committee between May 2003 and February 2004 meetings. The changes associated with the publishing of the 2004 Edition are called out by the designation “A04” in the margin next to the revised paragraph. Please note that the revisions published in the 2004 Edition do not become mandatory until March 31, 2005 due to the delays in publishing and delivering the books. However, you may begin using them immediately, as long as you identify construction to the 2004 Edition on the Manufacturers Data Reports. The Codes and Standards Group of HSB CT prepared the following summary of Code revisions. Summary tables containing revisions/additions/errata are provided for Sections I, II, III, IV, V, VI, VIII, IX, X, XI, & XII. In addition to the summary tables for each Code section, an Executive Summary of the more significant changes in the 2004 Edition has been provided. This year the Executive Summary includes helpful information about using the Codes in their new metricated format, and a descriptive overview of the new Section XII, Rules for the Construction and Continued Service of Transport Tanks. Commentary on revisions represents HSB CT's opinion of the changes, and is not intended to be an official interpretation of the ASME Code. Every effort was made to accurately describe the addenda changes. However, we caution Code users to always refer to the actual Code rules that apply and to use this document as a supplementary tool to the Code. Please contact HSB CT’s Codes & Standards group if further background information is desired on any of the revisions or Code Cases published. Code Cases This Synopsis includes a listing of Code Cases that have been newly approved or revised between May 2003 and February 2004. Since Code Cases are published four times per year, they are not actually part of the published Edition, however we use this document as an opportunity to alert our customers of the significant Code Cases approved during the past year. We have intentionally not included reaffirmations or annulments of Code Cases. The status of a known Code Case may be found by visiting ASME’s website, www.ASME.org , clicking on the Codes and Standards button, and then accessing the BPVC Code Case Database. Many of the cases listed in our Synopsis have not yet been published in hard copy by ASME; however, you can always obtain the latest publication status of a Code Case in this database on ASME’s website.

2004 ASME Code Addenda Synopsis Executive Summary

E-1

The 2004 Edition was published on July 1, 2004, representing revisions/additions/errata approved between May 2003 and February 2004 by the ASME B&PV Committee. The synopsis before you is the result of an extensive review of the changes published in the 2004 Edition compared with the B&PV Main Committee minutes to provide insights into the changes presented. The following Executive Summary highlights those revisions considered to be of major significance. John P. Swezy, Jr. Senior Code Consultant, HSB-CT Codes & Standards October 15, 2004 Mandatory Implementation Date The mandatory implementation date for the 2004 Edition of the Code has been postponed until March 31, 2005 due to the delays in publication and release. As before, the 2004 Edition may be optionally implemented upon receipt. Metrication

The ASME Boiler and Pressure Vessel Codes were “metricated” with the 2004 Edition. Code users must apply consistent units from design through certification, using either US Customary or SI units. Separate versions of Section II, Part D have been published in US Customary and SI units for Code user convenience. Nomenclature is now presented with either no units or US Customary units followed by parenthetical SI Units. Each Code Section now contains a new Mandatory Appendix listing the both the US Customary and SI units that are acceptable for use. Requirements tied to dimensions in the text with SI units may have been slightly revised when applying the conversion guidelines. Be sure to carefully check these quantities instead of assuming they are the same as before. Each Code Section now includes a Nonmandatory Appendix with the metrication philosophy and guidelines. The new Appendices are:

Code Book Mandatory Appendix Nonmandatory Appendix

I, Power Boilers II A-390 II, Materials, Parts A, B & C I N/A II, Materials, Part D 9 C III, Nuclear Components XXIV AA IV, Heating Boilers I M V, Nondestructive Examination II A VIII-1, Unfired Pressure Vessels 33 GG VIII-2, Alternate Rules for PV 27 N VIII-3, High Pressure Vessels 7 I IX, Welding and Brazing F G X, Fiber Reinforced Plastic 7 AH XI, Nuclear Inservice X P XII, Transport Tanks XII G

A more detailed explanation, the “Metricated Code Users Guide” prepared by the Technical Staff of HSB Global Standards is included in this Executive Summary.


E-2

Certified Individual The Board of Conformity Assessment has issued Conformity Assessment Policies

CAP-18 and CAP-19, permitting a single individual to carry out the responsibilities of BOTH the Certified Ind ividual and the Manufacturers Authorized Representative when signing Manufacturers Data Reports. This policy has been incorporated into construction Code requirements wherever a Certified Individual is required. Code Specific Revisions Section I New paragraph PG-68.7 (and associated Table PG-68.7) provides the proper technique for determining the relieving capacity of safety valves in superheated steam service. Paragraph PG-110 was revised to address the different approaches to be applied when stamping the valves, dependent upon the intended service application. Revised PG-99 and PG-99.1 to remove the 6% overpressure limit on hydrostatic tests, while retaining an upper pressure test limit of 90% of yield stress. As a result, boilers subjected to pressures greater than 6% over MAWP are no longer in violation of the Code and are still eligible for Code Symbol stamping, provided the resulting stresses do not exceed 90% of yield strength (at 0.2% offset) and there is no evidence of yielding on any components. This is a tremendous development for boiler manufacturers, as the capability to stamp and certify these boilers in compliance with Section I has now been greatly facilitated. New Paragraph PG-106.8.3 has been added, permitting Parts to be transferred between different Code fabrication facilities under the same corporate ownership without preparation of a Partial Data Report, providing such transfers have been addressed adequately in the Manufacturer's Quality Control Program. This practice was supported by Interpretations, but is now permitted within the Code text. PG-107.2 and PG-107.2.3 have been revised to implement the requirements for stamping and documenting the assembly of a completed boiler by multiple Assemblers. A partial Assembler is required to stamp the organization’s name, Code symbol, and the words “Partial Field Assembly” on a major pressure part listed on the partial Assembler’s P-3 Data Report. The stamping location must be described on the Data Report. This implements the provisions of Code Case 2365. Table PW-39 was revised for P-No. 1 materials, allowing the attachment of qualifying connections to a boiler with combination groove and fillet welds without post weld heat treatment for P-No.1, Group 1 or 2 materials. This provision is similar to the existing exemption for connection attachment by fillet welds. The required minimum PWHT temperature for P-No. 4 materials was increased to 1200oF (650°C), to more effectively temper the heat affected zones. Research has shown that this trans formation is only effective when a PWHT of 1200oF (650°C), is applied.


E-3

The requirements for NDE personnel certification have been relocated to new paragraph PW-50, and PW-51.5 and PW-52.4 were revised to require initial certification of Level III RT and UT examiners by written examination and performance demonstration, effective after the mandatory implementation date for the 2004 Edition of the Code (March 31, 2005). The provisions of older versions of SNT-TC-1A permitted designation of a Level III examiner based upon performance, without written tests or demonstrations. With publication of SNT-TC-1A-1992, initial certification of a Level III by examination and demonstration was required, but it was unclear how this affected current Level III Examiner qua lifications. The practice of recertifying previously designated Level III examiners based upon satisfactory performance is now specifically permitted, when acceptable within the employer’s written practice. This is a substantial change, impacting existing Written Practices of Manufacturers and NDE subcontractors. PW-54.3 was revised to allow welded attachment of non-pressure parts made of any carbon steel alloy (not just P-No.1) having a carbon content less than 0.2% to a P-No. 1 pressure retaining component after the pressure test. Weld size limitations and preheat conditions apply. This incorporates the provisions of Code Case 2292. This greatly benefits Manufacturers, allowing welded attachment of inconsequential non-pressure parts to power boilers, even when the parts are not Code materials. PEB-15 and PEB-18 have been revised to permit completed electric boilers to be trimmed for a lower pressure than the rating of the boiler pressure vessel, provided the installed safety valve has a set pressure corresponding to the MAWP of the completed boiler. A separate change to PEB-17.2 permits using a final test pressure corresponding to the safety valve setpoint. This precludes the potential for damage to sensitive components, and eliminates removal and replacement of the safety valve for performance of the pressure test. Section II, Parts A and B Appendix A for both Parts A and B was revised to add columns to indicate the acceptability of materials for use in Section VIII, Division 3 and Section XII construction. Many of the SA/SB specifications have been updated to conform to the latest ASTM A/B specifications. See Appendix A in Parts A & B for details. Section II, Part D A separate SI Units version of Section II, Part D has been published. A Statement of Policy was added to Subpart 1 to clarify which requirements are considered mandatory. Added a new column to Tables 1A, 1B & 3 to indicate material acceptability for use in Section XII construction. The new or revised specification changes are listed alphabetically by specification (i.e., SA, SB). Listings in the synopsis should only be used as a quick guide to significant changes; but the actual Code pages should be used to examine, review, compare and use the rules of Section II, Part D.


E-4

Appendix 6, Metallurgical Phenomenon, has been moved to Nonmandatory Appendix A. Nonmandatory Appendix B has been added to Section II, Part D to help the user understand the listing order for materials in the various stress tables and charts, making it easier to locate the stress line for a specific material more efficiently. Section V Article 4, Ultrasonic Examination, has been thoroughly rewritten and reformatted, including some significant technical changes. Manufacturers using UT examinations in Code construction should review this Article for possible revisions to their procedures. Section VIII, Division 1 UG-35 was rewritten to clarify that quick acting closures are to be designed with redundancy in the locking components, but not in the holding elements. When applying these requirements the Code user must understand the difference between holding elements and locking elements. A holding element is a part of the closure used to hold the cover to the vessel, and which directly carries the pressure load. Locking components are parts of the closure that prevent a reduction in the load and/or the release of a holding element. Put simply, the holding elements carry the load due to pressure; locking components prevent accidental opening of the closure under pressure. Additionally, a new Nonmandatory Appendix FF has been added, providing additional design information for the Manufacturer; along with installation, operating and maintenance guidelines for the owner. Since the philosophy driving the revised rules may be significantly different from a previous understanding of these requirements, Manufacturers should review their designs to ensure compliance with the revised requirements. New paragraph UG-116(a)(4) specifically addresses stamping of pressure vessels with external pressure ratings, and adds a new footnote to indicate that external pressure stampings are only required when external pressure is a specified design condition. Figure UG-118 now shows the placement for external pressure data. The abbreviation "FV" for full vacuum has been added to Appendix 3-2, legitimizing its use on Data Reports and stampings. Appendix W, Form U-1A has been revised to permit indicating both internal and external pressure and temperature ratings. UW-16(c)(2) was revised to adjust fillet weld sizing requirements for reinforced nozzles, and UW-16(f)(3)(a)(5) revisions clarified the reinforcement calculation requirements for nozzle attachments with single fillet welds. Manufacturers are encouraged to review their design calculations and weld sizing specifications to ensure compliance with the revised requirements.


E-5

Interpretation VIII-1-89-247R was issued, and UW-26(d) revised to require welding performed by subcontracted welders to be conducted at the location on the Certificate of Authorization, or field sites under their control. This is a significant departure from past practice (per Interpretation VIII-1-89-247), tending to permit subcontracted welding at off-site locations when UW-26(d) requirements are met. Interpretation VIII-1-92-167 was rescinded to maintain consistency between Interpretations. Manufacturers currently using off-site welding operations to supplement production needs are encouraged to review their QC Program for possible revisions. UW-40(f)(5)(c) revised the nominal thickness definition with regards to flange-to-nozzle or flange-to-shell attachment welds when determining PWHT requirements. This change only impacts designs where attachment welds fully penetrate the flange thickness. Code users applying this construction detail should review these requirements to determine the need to apply additional preheat or PWHT. Table UCS-56 was revised to increase the required minimum PWHT temperature for P-No. 4 materials to 1200oF (650°C), to more effectively temper the heat-affected zones. Research shows this transformation is only achieved when a PWHT of 1200oF (650°C) is applied. Part UHX has undergone further refinement to eliminate errors and to sharpen the requirements. Manufacturers constructing heat exchangers under the rules of Part UHX are encouraged to carefully review the provisions for potential impact on their designs. The Tables for acceptable material specifications previously located at the end of Subsection B have been relocated into the various Parts associated with those materials. For example, Table UCS-23 has been moved to Part UCS, and Table UHA-23 has been relocated to Part UHA, etc. Section IX New paragraph QW-290 addresses requirements for temper bead welding procedure qualification, collecting various requirements found in other Code sections into a single location with a common content. Manufacturers currently applying the construction Code rules for this welding technique should verify their procedures against these new guidelines for consistency. QB-305 was revised to reduce repetitive brazing operator performance qualifications when using automatic brazing processes. New brazing operator performance qualifications are still required when altering any of the essential variables noted in QB-351.2, but needlessly redundant qualification tests that do not demonstrate the skill of the operator have been eliminated.


E-6

Section XI IWA-2221 was revised to set the minimum lighting requirements for surface examinations using non-fluorescent techniques at 50 fc, superseding the lighting requirements given in Section V, Articles 6 & 7. Case N-685 allows immediate use of these provisions. Revised VII-4121, VII-4122, and VII-4123 and Note (b) of Table VII-4110-1 to eliminate the minimum nuclear examination experience requirements for UT Level III examiners. The combination of non-nuclear experience and the performance demonstration rules of Appendix VIII make nuclear experience unnecessary. Added a new Nonmandatory Appendix N to summarize the NDE qua lification and Certification requirements. Section XII

A new Code Section XII, Transport Tanks, has been published to provide rules for the construction of pressure vessels used in intermodal transport of hazardous goods. These rules are not mandatory until incorporated by reference into the Title 49 DOT rules. Since there is a public review period to be observed, this may be at least a year off. In the meantime, current DOT rules are still in effect. The rules set forth in this book are very similar to Section VIII, Division 1. Applicability is limited to cryogenic portable tanks in excess of 450 L (120 gal) for the transport of refrigerated non-toxic gasses. Other types of tanks will be addressed in future additions to this Code section. For a more detailed explanation of these requirements, and the primary differences between Section XII and Section VIII, Division 1 see “Section XII Portable Tanks: A Detailed Overview” prepared by the Technical Staff of HSB Global Standards found at the end of this Executive Summary.

Metricated Code User’s Guide

M-1

With the publication of the 2004 Edition, the ASME Boiler and Pressure Vessel Code will be presented in a metricated format. This guide attempts to address the underlying principles for applying the metricated Code rules. The conversion philosophy for metricating the ASME Code was selected after careful consideration. A written conversion guideline was prepared, directing the actions of the individual book sections as they began metricating their rules. Some conversions are “soft” or determined using a conversion factor, with appropriate rounding to a significant number of places. Other conversions have been “hard” converted, or made with an empirically assigned numerical value favorable for common usage, but which may be less accurate mathematically. Hard conversions are used where industry norms are commonly used, to maintain more evenly spaced intervals between increments, or to maintain underlying concepts of the Code rules. The conversion guideline document used for metrication is being published as a Non-Mandatory Appendix to provide guidance for Code users when unit conversions are necessary. Examples of Soft and Hard Conversions Conversion Method

Unit Soft Hard Comment ¼ in 6.35 mm 6.0 mm Represents a 5.5% difference between soft

and hard conversion 3/8 in 9.525 10 mm Represents a –5% difference between soft

and hard conversion 1 hour/in 2.36min/mm 2min/mm Although this results in a heat treatment of

only 51 minutes for a 25.4 mm thick section, this is considered to be within the range of intended precision of the US Customary requirement.

15 min/in 0.591 min/mm

0.5 min/mm Although converting and rounding would give 0.6 minutes/mm, it was necessary to use 0.5 minutes/mm to be consistent with the rounding for 1 hour / inch [2 min/mm].

The greatest difference in the metricated Code is the publication of two distinctly different versions of Section II, Part D. One is given in US customary units, and the other in the metricated SI units, and must be purchased separately. It is also important to note that the allowable stress tables require careful application. Stress values will appear in the various tables at corresponding temperatures that may exceed the upper temperature limits for the materials. These “out of bounds” values are provided to allow the Manufacturer to perform interpolations for their design temperatures, up to the upper temperature limit for a given stress line. The upper temperature limit is not to be violated.

The upper temperature limit in the SI table is 538°C [soft conversion], however a temperature point at 550°C is given only to allow interpolation at 538°C; design above 538°C is not permitted. In the construction Codes, the specified units have been deleted from the defining statements for variables found under the nomenclature for with design formulas. This was done to simplify presentation of variables in the Code; otherwise every variable would have to have two units (US Customary & SI) defined. Some design formulas include numerical constants, which are a function of the units and not geometry. When this is the case, alternate formulas are provided for use with the specific units. When performing design calculations the user must apply pressure units compatible with the units for allowable stress. Since the metricated allowable stresses are expressed in MPa, the pressure should also be expressed in these units for the calculations to be correct. The metricated B&PV Code was prepared based on the use of consistent sets of units as presented in Table (1). Manufacturers of boilers and pressure vessels are advised to carry out all code required calculations using the consistent set of units presented in this Table (1). Note that once a set of units is selected [US Customary or SI] the Manufacturer shall apply a construction approach utilizing the selected unit set from design through certification. It is not permissible to selectively apply differing set of units at various stages of construction, but to follow a consistent approach.

Angle degrees or radians degrees or radians Boiler Capacity BTU/hr Watts (W) A working knowledge of the various SI units appearing in the metricated ASME Code is helpful in understanding the metricated Code. Table (1) is included in all the Code Sections. Table (1) lists both SI and US Customary units, but some of the SI units are different from those found on the SI Units pages in previous Editions of the Code. Below is further explanation of the different units and their use in the code. Length/Area/Volume Linear dimensions are given in millimeters (mm). Area is expressed in square millimeters

(mm2). Volumes are given in cubic millimeters (mm

3). Liters (l) may be used in text

discussions, but not calculations. Mass is expressed in kilograms (kg). The linear and volume units have achieved some familiarity by users of the US Customary unit system, through their parallel use on many things in American life. The conversions are straightforward, and the conversion factors often familiar, so these units are usually handled with little fanfare. Temperature Relative temperature is expressed in degrees Celsius (C), and absolute temperature in Kelvin (K). Converting temperature units is a two-step process, since the “zero” reference point on each


M-4

scale represents significantly different real temperatures. First the user must make an adjustment to reach a common point of reference, and then apply a conversion ratio. Depending upon the direction of the conversion, sequencing of these operations changes. If simply converting an absolute value between different temperatures, reference point adjustment is not necessary. For Example, a 30°F reduction in impact test temperature would not be equivalent to -1.1°C [soft conversion of 30°F], but instead to 17°C; see below. In US Customary 70°F - 40°F = 30°F, and then converting the US Customary temperature to metric 21.1°C – 4.44°C = 16.667°C = 17°C Pressure Some Code users may be familiar with the pressure unit “bar”, where a bar is equal to the average value of atmospheric pressure, 14.5 psi. In this case 500 psi converts to about 35 bar. A bar is considered a “local customary unit”, which may be listed parenthetically on documentation and Data Reports, but is not addressed in the metricated requirements of the ASME Code. SI units of pressure vary, depending on their magnitude. Smaller values are expressed in kPa, and larger values (150 psi and greater) are expressed in MPa. The converted quantities may feel a bit odd, as the numerical value seems disproportionate to the original quantity. For example, 500 psi converts (by exact conversion) to 3.448 MPa or 3448 kPa. Force Force is expressed in newtons (N). Roughly, a pound of force is equal to about 4.5 (N). Energy (as in Charpy fixed energy) is expressed in joules (J). A ft- lb of energy is about 1.3 Joules. Boiler output is rated in watts (W). A watt is about 3.4 BTU/hr. PWHT Postweld heat treatment requirements and exemptions are based upon the section thickness, with heat treatment requirements stated as a specified holding time at a specified temperature. Both thickness and temperature are expressed in the units chosen by the Manufacturer. The holding times have been converted from 1 hr/in to 2 min/mm and from 15 min/in to 0.5 min/mm. These are “hard” conversions, used for consistency with the intended precision of the US Customary requirement, and to improve the correlation between them. Pressure Relief Devices Safety Valve capacities are expressed in units of volume per unit of time or mass flow rate. The metricated units for safety valve capacity will be kilograms per hour (kg/hr) for saturated steam, liters per minute (l/min) for water flow, and Standard Cubic Meters per Minute (SCMM) for gaseous flow. The term SCMM is based on standard conditions of 20 degrees Celsius and 101 kPa verses 60 degrees Fahrenheit and 14.7 psia. Summary An ASME certificate holder usually begins the fabrication process with a design. Converting units back and forth increases the probability of introducing errors in the design process. Published data such as allowable stresses have been converted in the Code, but the conversions


M-5

are often “hard” conversions. Using the soft conversions approach would result in widely disparate stress values. This helps explain why the designer is required to select a single unit format, and apply it consistently through the entire Code construction process. The vessel dimensions, pressure and temperature ratings, allowable stresses, and in some cases even specific design formulas must adhere to this principle. Constructing identical objects to comply with both unit systems will be more cumbersome. It requires the Manufacturer to have a copy of Section II, Part D in both sets of units to properly apply the Code rules. Separate design packages, welding documents, and Data Reports forms may be necessary. Some objects constructed for shipment outside the US could possibly require re-certification or re-registration of the design to meet import requirements. Manufacturers must evaluate these situations for each market they serve. Finally, marking and certification must be in the selected unit set [Table (1)], however alternate units may be listed in parentheses.

ASME Section XII Transport Tanks A Detailed Overview

T-1

Section XII, Rules for the Construction and Continued Service of Transport Tanks has been introduced with the 2004 Edition of the ASME Boiler and Pressure Vessel Code. It addresses the construction, continued service, and repair of Transport Tanks. A Transport Tank is defined as a pressure vessel for the transportation of dangerous goods via highway, rail, air or water. The scope of Section XII is limited to vessels having a volume greater than 450 liters (120 gallons), designed for a maximum pressure rating of 0-207 bar (full vacuum to 3000 psi), with design temperatures between –269 C and 343 C (-452 F to 650 F), where the vessel shell or head thickness is not greater than 38 mm (1-1/2 in). The geometric scope is the same as with Section VIII, Division 1. Definitions for terms used in this Section (such as “dangerous goods”) can be found in Mandatory Appendix III. In some aspects, Section XII is a significant departure from the other pressure equipment Codes. Unlike the other ASME Codes for new construction of pressure equipment, the Scope of Section XII does not end with the application of the Code symbol stamp on the completed vessel, but also includes provisions for determining “fitness for service” to recertify the tanks for continued service, and the performance of repairs and alterations to transport tanks. Section XII presents information somewhat differently. Section XII was written to encourage acceptance by the international community, with SI Units as the primary form of expression, and US Customary units as secondary. Section XII is presented in a format similar to Section VIII, Division 2, with the requirements found in various Parts:

Part TG: General Requirements Part TM: Materials Part TD: Design Part TW: Welding Part TF: Fabrication Part TE: Examination Part TT: Testing Part TR: Pressure Relief Part TS: Stamping and Certification, and Part TP: Repair, Alteration, Testing, and Inspection for Continued Service.

Most of these Parts have been further subdivided into Articles, such as TG-1 through TG-4 within Part TG, General Requirements. Section XII subdivides Parts into Articles, grouping common topics together. The Parts are followed by Modal Appendices. Modal Appendices provide mandatory requirements applicable to specific types of vessels. The Modal Appendix requirements are additive, and take precedence over primary requirements. Only Modal Appendix 3, Portable Tanks is currently complete, containing only Article 1, Cryogenic Portable Tanks. Modal Appendices are being prepared for Cargo Tanks, Rail Tank Cars, and Ton Tanks, and will be published as they become available.


T-2

The Modal Appendices are followed by Mandatory Appendices, containing requirements more broadly applicable to multiple types of tanks. These requirements are invoked by the Code text, with most of those currently in place addressing NDE requirements. Others are in preparation to address Special Commodities and Low Pressure Tanks. The Mandatory Appendices are followed by Non-Mandatory Appendices, containing recommended practices and guidelines applicable to specific tank configurations or types of construction. The Non-Mandatory Appendices may present construction techniques as alternative options for the Manufacturer to consider. Section XII will be familiar to those experienced with using Section VIII, Division 1. Many of the provisions were directly adopted from Section VIII, Division 1. Be careful when applying Section XII requirements, because some of the requirements brought over from Section VIII, Division 1 have been modified in transition, and are not necessarily identical in Section XII. Since the formatting is different from Section VIII, Division 1, the requirements are located a bit differently. For example, the general requirements for design, materials, fabrication, and documentation are located in the respective Parts dealing with those areas, and not within the general requirements. Part TG, General Requirements is very brief, containing little beyond the Scope of the document and primarily administrative requirements. The specific responsibilities of the Owner, Manufacturer, and Inspector are found in Article TG-3. These responsibilities are virtually the same as those found in U-2(a), UG-25(a), UG-90 & UW-2(a) of Section VIII, Division 1. General material requirements are in Part TM, Article TM-1; including acceptable specifications, material recertification, standard pressure parts, material identification, and cut edge examinations. Subparagraphs include specific material requirements for High Alloy, Non-Ferrous, and Quenched and Tempered materials. Impact test requirements and exemptions are located in Article TM-2. Impact test exemption provisions similar to UG-20(f) in Section VIII, Division 1 are in TM-240.4, but apply material curve thickness limits only half as thick as similar limits in UG-20(f). Design calculations in Part TD, Design Requirements are essentially identical to those in Section VIII, Division 1. Since transport tanks are used in dynamic service environments, additional design considerations are given in the Modal Appendices for the unique transport and service modes. The units for pressure are not given in the nomenclature definitions, but must be the same as those used for allowable stress for the calculations to work properly. Though this Section uses “bar” when discussing general requirements associated with pressure, this is a local customary unit that will not work in design calculations.


T-3

Part TW, Requirements for Tanks of Welded Construction contains requirements for joint designs, efficiencies, attachment details, and weld sizing identical to those in Section VIII, Division 1. Welding procedure and performance qualification must be in compliance with Section IX requirements. Brazing is not currently permitted for fabricating transport tanks. Fabricating requirements are located in Part TF, Fabrication Requirements, including: material identification, cutting, forming, joint alignment, controls for welding operations, acceptable weld profiles, postweld heat treatment (PWHT), corrosion resistant linings, and special fabricating requirements associated with specific material types. The requirements are identical to Section VIII, Division 1. Visual Examination requirements are addressed in this Part, but are not handled as an NDE technique. Examination requirements are found in Part TE, Requirements for Examination Procedures and Personnel Qualification. Four main types of NDE are addressed, including radiographic (RT), ultrasonic (UT), magnetic particle (MT), and liquid penetrant (PT) examinations. RT and UT examinations require personnel qualification per their employer’s written practice, using SNT-TC-1A, CP-189, or ACCP as a guide. Examination personnel qualified by demonstration per the Code requirements may perform PT and MT surface NDE. Testing requirements are found in Part TT, Vessel Testing. Hydrostatic tests are performed at 1.3 x MAWP, pneumatic testing permitted at 1.1 x MAWP, and both are multiplied by a temperature correction stress ratio. Proof testing for design verification is limited to burst testing, though Section XII permits cessation of the test when pressure has reached the point where the pressure rating has been sufficiently justified. This Part also addresses spark testing of elastomeric linings on transport tanks. Overpressure protection requirements are found in Part TR, Pressure Relief Devices. While Section XII has rules for producing pressure relief devices and applying the “TV” or “TD”, it also accepts the use of pressure relief devices that are marked with the ASME “UV” and “UD” symbols provided these devices meet the requirements of the Modal Appendices and are rated consistent with the intended service conditions. Pressure Relief Valves not complying with Section XII requirements may be installed as permitted within the Modal Appendices. This allows certain liquid bulk transport applications to install specialized safety valves meeting unique set point and lifting criteria. Safety valves produced under Section XII and marked with the “TV” symbol are required to undergo seat tightness testing as set forth in API-527 after the normal production testing. Code Stamping requirements are located in Part TS, Content and Method of Stamping Transport Tanks. A “T” Code symbol is applied, with SI units as primary units. The service class designator is directly under the Code Symbol. Type of construction, RT, and HT designators are below the Class designator. The Class designator replaces any special service designators. Section XII Parts shall include a Class designation in their stamped information.


T-4

Part TP contains Requirements for Repair, Alteration, Testing, and Inspection for Continued Service. Repairs of Transport Tanks are to be made by an organization with a National Board R Stamp Certificate of Authorization, and be performed in compliance with the National Board Inspection Code. Inspection requirements for welded repairs, alterations and ratings are dependent upon the class of service. Owner/User Inspectors are also permitted to conduct these inspections within their normal restrictions. The required inspections and pressure tests for continued service may be performed by the tank Owner or User, provided that no re-rating, welded repairs, or alterations are undertaken or required. Tanks shall be marked to indicate the completion of periodic tests and inspections in compliance with the jurisdictional authority. Additional fitness for service inspection and test requirements are addressed in the Modal Appendices. Section XII will also feel familiar to those with experience using DOT specifications. Following the pattern set by other intermodal hazardous goods transport container standards, Section XII defines different classes of vessel service; Class 1, 2, or 3. The vessel class designation is assigned by Modal Appendices for the specific type of transport tank. Class designations are assigned based upon the hazard class of dangerous goods transported, and the relative risk associated with the particular transport mode. In some cases, the class of service invokes alternate construction requirements for weld joint designs, NDE, etc. Each Class requires a different level of inspection associated with its construction, service, and repair. Class 3 tanks may be self-inspected by the Manufacturer, with object certification by a Certified Individual (CI). Class 2 tanks require a third party Qualified Inspector (QI), employed by an ASME accepted Qualified Inspection Organization (QIO). Class 1 tanks require involvement of an Authorized Inspector (AI), employed by an ASME accredited Authorized Inspection Agency (AIA). Each level of Inspector is also permitted to carry out inspections on tank classes below their qualification level if desired by the Manufacturer. Rules for qualifying and designating the various levels of inspectors are found in QAI-1, an ASME procedural document containing qualification requirements for Inspectors and Inspection Organizations. These rules for CIs, QIs, and QIOs are not fully developed, but appear to be headed in the following direction:

CI: Responsibility for training, qualification, and designation of a CI is assigned to the Manufacturer, and includes conduct and documentation of training and experience, completion of a written examination, and formal designation by the Manufacturer.

QI: Qualification will follow ASME-developed criteria, including completion of a written examination, with employment and formal designation by a QIO. QIO’s will be qualified by ASME, but not on the same level as an AIA. The QI and QIO roles are similar to the current DOT Inspector and DOT Inspection Organization, and will include “fitness-for-service” inspections, certain types of repair inspections, and inspections associated with new construction of Class 2 tanks.


T-5

Non-Mandatory Appendix C contains the required Data Report Forms for Section XII, including instructional notes for their completion. There are separate report forms for each service class designation (hence the “A”, “B” and “C” suffix designations), since each class has different inspection certification requirements. On all Section XII report forms, the “Location of Installation” line has been replaced with a line for identifying the Competent Authority (or jurisdiction) and the specific regulation the tank is built to comply with. The special service designation line has been replaced on the data report and partial data report forms with a volumetric capacity blank.

The Data Report Forms (Form T-1A, T-1B, & T-1C) are essentially the same as Form U-1A in Section VIII, Division 1. Besides the differences mentioned above, the line for recording shell thickness has been revised to require indication of the minimum required thickness, rather than nominal thickness as required in Section VIII, Division 1.

Partial Data Report Forms (Form T-2A, T-2B, & T-2C) are essentially the same as Form U-2A in Section VIII, Division 1 except for the differences noted above.

Supplementary Information Sheets (Form T-4A, T-4B, & T-4C) are essentially the same as Form U-4 from Section VIII, Division 1 except for the differences noted above.

HSB Code ServicesSynopsis of the 2004 Addenda to the ASME Code

Friday, October 15, 2004 Page 1

Errata Items Errata PG-37.3, revised reference to "PW-33" to correctly reference "PG-33";PG-73, deleted editorial comment to publisher that appeared in print between PG-73 and PG-73.1;PG-93.1, revised references to PG-31(i) to read (i-1) and (i-2);

PG-8.4 & PG-67.7 Addition SB-148 Aluminum Bronze Castings Grades C65200 and C95400, are now acceptable for use in PG-8.4, PG-8.4.2.1, and PG-67.7 under the same conditions as currently permitted for SB-61 leaded tin bronze castings.

PG-9.6 & PW-39 Addition Material Specifications SB-265 Titanium and Titanium Alloy Strip, Sheet and Plate; SB-338 Seamless and Welded Titanium and Titanium Alloy Tubes for Condensers and Heat Exchangers;SB-348 Titanium and Titanium Alloy Bars and Billets; SB-861 Titanium and Titanium Alloy Seamless Pipe; SB-862 Titanium and Titanium Alloy Welded Pipe in Grades 1, 2 and 3 are nowaccepted for use in new paragraph PG-9.6 as instrument wells. This revision also adds a table for P-No. 51 materials to PW-39.

PG-19 Revision Incorporated Code Case 2083, permitting the use of Alloy 690 (58Ni-29Cr-9Fe) in superheater construction under Section I rules to a max temperature of 1200F.

PG-19 Revision Adopted SA-213-TP347HFG for use in superheater construction under Section I rules.

PG-42.1.13 and Table A-360

Revision ASME B16.28 has been withdrawn by the B16 Committee after incorporating its provisions into ASME B16.9. This action deletes references to this standard in PG-42.1.13 and Table A-360.

PG-67.2.1 Revision Revisions to PG-67.2.1 clarify that the Manufacturer must determine the maximum designed steaming capacity (MDSC) for a boiler while operating at the rated MAWP. Some boiler arrangements have a higher MDSC at a lower pressure, so this action was necessary to clarify how to determine the required safety valve capacity.

PG-68.7 & PG-110 Revision New paragraph PG-68.7 (and associated Table PG-68.7) provides the proper technique for determining the relieving capacity of safety valves in superheated service. Paragraph PG-110 was revised to address the different approaches to be applied to stamping the valves, dependingupon their intended service applications.

PG-99 Revision Revised PG-99 and PG-99.1 to remove the 6% overpressure limit on hydrostatic tests, while retaining upper limit to 90% of yield. As a result, boilers exposed to pressures greater than 6% over MAWP are not automatically in violation of the Code and are still eligible for Code Symbol stamping, provided that the 90% of yield strength limit has not been exceeded, and there is no evidence of yielding on any components.

PG-106.8.3 Revision New Paragraph PG-106.8.3 permits the transfer of Parts between different Code fabrication facilities having their own Code Certificates but operating under the same corporate ownership without preparation of a Partial Data Report. These transfers must be addressed adequately in the Manufacturer's Quality Control Program. This practice was previously supported by Interpretations, but is now adressed within the Code.

PG-107.2 Revision PG-107.2, PG-107.2.3 & PG-107.2.4 have been revised to implement the requirements of Code Case 2365, for stamping and documenting the assembly of a completed boiler by multiple Assemblers. A partial Assembler is required to stamp the organization’s name, Code symbol, and the words “Partial Field Assembly” on a major pressure part listed on the partial Assembler’s P-3 Data Report. The stamping location must be described on the Data Report.

Code Book: I

Part:

Subpart/Table: Part PG

Paragraph Type Subject



PG-112.2 Revision A new Data Report Form, Form P-2B, is being introduced to allow for properly documenting the construction of electric superheaters and reheaters. Appropriate references to the new form have been inserted into the Appendices, including the form itself, and instructions for its completion.

PG-112.5 & PG-113 Revision Revised paragraphs PG-112.5.1, PG-112.5.2., PG-113.1 and PG-113.3 to delete the use of Form P-5 as a Master Data Report; and describe it as a Summary Data Report, rather than a Master Data Report. The Form itself was also revised to include a signature line for the Authorized Inspector. Various Code text was revised to address this change in use of Form P-5.

Errata Items Errata Figure PW-15, revised the weld strength model formula for sketch (b) to read "t2 in tension" versus "t2 in shear", revised sketch (c) to properly align the dimension "WL1" to the fillet leg, terminate dimension "d" at the Nozzle ID, and revise the "W" formula in part (2) to delete "A2"and substitute "A5" for "A3";Figure PW-16.1, revised nomenclature for sketch (y) to change "tn" to "tc";PW-43.1.2, revised strange appearing angle symbols to read as lower case script "L";PW-53.4.2(c), revised the word "of" in the last line preceeding "1/4" to read "or"

PW-27.1 Revision Revisions to PW-27 extend the previous limitations for resistance welded products to apply to resistance welding of long seams by Manufacturers. Previous requirements imposed no limits for resistance welding upon ASME Certificate Holders. Circumferential butt welds and pressurebearing attachment welds remain unrestricted, based upon the limited use of resistance welding in those applications and the absence of a strong technical basis for adding such restrictions.

PW-27.3 Revision Revised the reference to NDE requirements for electroslag welding to direct the reader to their new location in Table PW-11. These requirements had previously been located in PW-11.2.2

PW-27.5 Addition New paragraph PW-27.5 restricts welding processes to GTAW and GMAW when welding UNS N06230 materials using filler metals of the same chemical composition. Research has uncovered a tendency for microfissures to form when using covered electrodes.

PW-50 Addition Added new paragraph PW-50 to address NDE personnel certification requirements, and deleted PW-51.5 and PW-52.4. Initial certification of Level III RT and UT examiners must now be conducted by written examination and performance demonstration. Provisions were added to preserve the practice of recertifying previously designated Level III examiners based upon satisfactory performance, as permitted by the written practice. This is a significant change, requiring a review of written practices for revision.

PW-51.1 Revision Revised the reference to the geometric unsharpness requirements found in Section V, Article 2 due to a change in their location. The exception taken to those requirements remains without revision.

PW-54.3 Revision PW-54.3 has been revised to allow the attachment of non-pressure parts made of any low carbon steel alloy with a carbon content less than 0.2% to P-No. 1 pressure retaining components after the pressure test, when weld size limitations and preheat conditions are met. This incorporates Code Case 2292 into PW-54.3, expanding these provisions for applicability to low carbon steels other than P-No. 1 materials.

Table PW-11 Revision Revised Table PW-11 to reference the requirements for NDE personnel certification requirements. An editorial change has been made to A-360 to reinstate CP-189 as a referenced standard, as it had been inadvertantly deleted in a previous Addenda

Table PW-39 Revision Revisions to the PW-39 PWHT Tables add restrictions against cold working strains of greater than 3% on weld overlaid P-No's 1, 3 and 4 pipe and tubing, due to the cracking that results from excessive strains.

Subpart/Table: Part PW




Table PW-39 Revision Revised Table PW-39 to increase the required minimum PWHT temperature for P-No. 4 materials to 1200F, to more effectively temper the heat affected zones. This revision will be consistent with B31.1 when that revision is completed.

Table PW-39 Revision Revised PW-39 for P-No. 1 materials to allow the attachment of qualifying connections to a boiler with combination groove and fillet welds without post weld heat treatment for P-No.1, Group 1 or 2 materials, incorporating the provisions of Code Case 2332.

PWT-11.2 Errata PWT-11.2, revised reference to PG-39 to read "PW-39"

PFT-16 & PFT-51.1 Revision The Adamson type furnace is obsolete and not used any longer. Deleted PFT-16 and Figure PFT-16, and revised PFT-51.1 to delete references to Adamson furnaces.

PFT-23.2 Revision The formula for determining the MAWP of a wrapper sheet in a locomotive type boiler has been revised to allow the use of the current allowable stress values, instead of a fixed value for allowable stress. This updates the formula for the current design margins, and permits the use ofthe actual stress values for the material in question.

PFT-25.2 Revision Revisions to PFT-25.2 clarify that a water cooled turnaround chamber may be considered equivalent to a furnace in providing a point of support when determining staying requirements for heads on a firetube boiler.

PFT-43.5.2 Errata PFT-43.5.2, revised the word "under" to read "less than or equal to"

PEB-5.3 Revision Revised PEB-5.3 to include 347 stainless steel, completing incorporation of Code Case 2042.

PEB-15 & PEB-18 Revision This revision permits completed electric boilers to be trimmed for a lower pressure than the rating of the boiler pressure vessel, provided the installed safety valve has a set pressure corresponding to the designated MAWP.

PEB-17.2 Revision PEB-17.2 has been revised to permit performing a final pressure test on a completed electric boiler at a test pressure corresponding to the safety valve setpoint. This precludes the potentialfor damage to sensitive components, and makes it unnecessary for the Manufacturer to remove and replace the safety valve to perform the pressure test.

A-301 Revision The revisions to Appendix A-301 clarify that the Certified Individual and the Authorized Representative signing the Manufacturer's Data Reports may be the same person.

Subpart/Table: Appendix




A-360 Revision Adopted the 2001 Edition of ASME B16.11. The earlier Edition included provisions for fittingsto be made of nonstandard materials upon agreement of the purchaser and the manufacturer. This provision has been removed. Because of the way Section I implements ASME product standards, there is no effective impact upon Section I.

A-360 Revision Adopted the "a" addenda from 1998 for B16.34

A-370 Revision Appendix A-370 was revised to delete statements that are inconsistent with ASME Conformity Assessment Policy, and to add new certificate scopes for coverage of parts fabrication.

A-390 Addition A new Appendix A-390 has been added to Section I to provide the guidelines used in Metricating the Code. These guidelines are to be applied as necessary when performing conversions other than those prepared by the Code Committeees.

Errata Items Errata Figure A-69, revised tube diameter nomenclature from "dt" to "dl", and revised formulas associated with example

Code Case 1325-17 Revision Code Case revised to apply Section II, Part D allowable stresses to these materials (UNS N08800 and N08810).

Code Case 1750 Revision The CC 1750 was revised to accept various materials with alternate base metal chemistry for use in pressure relief devices.

Code Case 1750 Revision Revised CC 1750 to permit restricted application of tack welds on ASTM A576 Grade 1117, but only in the secondary pressure zone.

Code Case 1750-16 Errata Code Case 1750-16, Table 1, deleted the minus sign from the temperature range for SA-352, Grade LCC

Code Case 1827-1 Revision Revised CC 1827-1 to reference allowable stresses from Section II,Part D.

Code Case 1949-3 Revision Revised CC 1949-3 for use in Section I construction in water wetted service, and apply the Section II, Part D allowable stresses.

Code Case 2010-4 Revision Allowable stress values have been updated to reflect the 3.5 design margin.

Code Case 2235 Revision Some of the nomenclature in Figure 5 of the Case was not properly defined. This revision corrects that error.

Code Case 2328-1 Revision Revisions were made to the chemistry and hardness limits to provide additional protection against hot shortness during welding and tubing production. Other mechanical property adjustments and minor chemistry changes were made to bring the requirements of the code case into conformance with those of the Japanese code.

Code Case 2330 & 2331 Revision Revised Code Cases 2330 and 2331 to remove the specific radius requirements for the out surface of a localized thin area. The sharp corner (i.e. without a radius) at the outer surface is not known to affect the fatigue strength or burst strength of the vessel in the presence of an LTA. Thus a blend radius is not required at this location.

Code Case 2357 Revision Reaffirmed Code Case 2357, Use of Ni-Fe-Cr Alloy UNS N08801, due to continuing need in industry.

Code Case 2374 Addition This is an implementing Code Case to permit early use of revisions to PEB-15, which permit mounting of safety valves in other than vertical positions when the qualifying conditions can be satisfied. The actual Code revisions should appear in the 2004 Edition.

Code Case 2440 Addition Implementing Code Case to allow immediate use of this material pending publication in Section I and Section II, Part D.

Code Case 2444 Addition Adopted CC 2444, permitting alternate requirements for Code required inspection openings andpiping connections for small scale model boilers

Article 2, T-277.2(b)(7) Revision New paragraph T-277.2(b)(7) permits the use of only three IQIs on flat or curved subjects when three or more film cartridges are used in a single exposure. The IQI image sensitivity requirements and film density requirements must still be met, providing a natural limit for the length of weld that may be successfully examined using this technique in a single exposure. Previous subparagraphs (7) and (8) have been redesignated as (8) and (9).

Article 2, T-283.2 Revision Revised T-283.2 to allow use of thinner IQIs with hole sizes capable of demonstrating equivalent or better radiographic sensitivity. Previously the selection criteria for IQIs of equivalent sensitivity was limited to IQIs along the same row of Table T-283.

UG-35.2, Appendix FF Revision UG-35.2 was rewritten to make it clear that quick acting closures are to be designed with redundancy in the locking components, but not in the holding elements. UG-35.2(c)(2) cautions designers that rules of Appendix 2 may not be applicable for designs such as breach lock closures. UG-35.2(c)(3) cautions designers to consider the effects of cyclic loading and mechanical wear on the holding and locking components. Added Appendix FF, providing additional design information for Manufacturers; and installation, operating and maintenance guidelines for the owner.

UG-36(c)(3)(d) Revision Added a new final sentence to UG-36(c)(3)(d), requiring reinforcement exempted openings to belocated such that their centerline is no closer than their finished diameter to any reinforcing material of an adjacent reinforced opening. Note that this new requirement should have been published as new paragraph UG-36(c)(3)(e), and not as an addition to UG-36(c)(3)(d). It is meant to apply to any small opening exempt from reinforcement by UG-36(c)(3).

UG-47(b) Revision Staying of plates with stay bolts or rods is only permitted on material with a minimum thickness of 5/16" (8 mm). The previous rules in UG-47(b) provided an exemption to this rule for UW-19 construction, which has now been extended to apply to dimpled and embossed assemblies under Appendix 17.

UG-79(c), UCS-79(e) Revision The requirements for documenting strain relieving heat treatments applied after cold forming of carbon steel material were moved from UCS-79(e) to UG-79(c). In addition, this requirement was extended to cold forming applications involving high alloy material [UHA-44], non-ferrous material [UNF-79] and high tensile strength material [UHT-79].

UG-101(l)(1) & UG-101(o)(1)

Revision A reference to SA-370, paragraph 13.1 was added to paragraphs UG-101(I)(1) & UG-101(o)(1), clarifying “definitely determinable yield point” to help Code users understand that proof tests such as brittle coating and displacement measurement tests are not acceptable for materials that do not display a sharp kneed portion on their stress-strain curve, such as austenitic stainless steels. This is an important clarification to a rule often missed by Code Users.

UG-116(a)(4), Figure UG-118, 3-2, & Appendix W

Revision UG-116(a)(4) added to address stamping of pressure vessels with external pressure ratings. A new footnote indicates external pressure stampings are only required when external pressure is aspecified design condition. Figure UG-118 shows placement of external pressure data. "FV" for full vacuum was added to Appendix 3-2, legitimizing use on Data Reports and stampings. Appendix W, Form U-1A revised to indicate both internal and external pressure and temperature ratings. Renumbered previous paragraphs UG-116(a)(4) thru (6) as (a)(5) through (a)(7).

UG-125(c)(2), Appendix M, M-13(a)

Revision UG-125(c)(2) adds reference to Appendix M for considering fire engulfment overpressure protection. Additional guidance was added to Appendix M, M-13 to notify the Code user thereare circumstances when a vessel exposed to fire experiences a pressure rise that is insufficient toopen safety relief devices. It may be necessary to review other technical standards for additionalrules for protecting the vessel from fire. Some significant formatting problems were noted in Appendix M afetr revision, so contact Codes and Standards if assistance is needed.

UG-136(d)(5) Revision Added the phrase "or another specification agreed to by the user" to the second sentence of UG-136(d)(5). This effectively permits the use of any leakage test criteria or standard for seat tightness of pressure relief valves agreeable to the Manufacturer and User.

UW-13 (g) was added to invoke requirements of Appendix 20 for these type stub ends. Previous UW-13(g) was redesignated as UW-13(h). Appendix 20, 20-1 was revised to add lap joint stub ends into the Scope of the Appendix, and 20-4 was revised to remove language tending to exclude lap joint stub ends.

UW-16(c)(2) Revision The current rules in UW-16(c) for sizing inner and outer fillet welds on reinforcing plates are inconsistent with the sketches in Fig. UW-16.1 due to revisions to the Figures over the years without corresponding revisions to the governing paragraph. This revision corrects these inconsistencies. Paragraph UW-16(c)(2)(c) now requires a cover fillet weld with a minimum throat dimension of tc at the inner edge of a reinforcement pad attached to the nozzle with a fullpenetration weld.

Subpart/Table: Part UW




UW-19(c)(2) Revision A new sentence was added to UW-19(c)(2), informing Code users that a value of E = 0.80 shall be used in UG-101[proof test] calculations to determine the allowable working pressure for dimpled or embossed assemblies fabricated per the rules for welded stayed construction of UW-19(c). This action incorporates information previously presented in an Interpretation.

UW-26(d) Revision UW-26(d) was revised to require welding by subcontracted welders to take place at the address on the Certificate of Authorization or the final installation site. This is a significant departure from past practice. Interpretation VIII-1-89-247 permitted using subcontracted welding at locations other than the Certificate Holders address or final installation site. Interpretation VIII-1-89-247 was revised [VIII-1-89-247R] and Interpretation VIII-1-92-167 rescinded to assure consistency between Interpretations and applications for using subcontracted welders.

UW-40(f)(5)(c) Revision Revised UW-40(f)(5)(c) to redefine the governing thickness for attaching flanges per Figure 2-4, sketch (7) as the actual weld thickness through the flange ring. This corrects PWHT application requirements when weld thickness is substantially greater than the shell thickness, causing dramatically higher heat inputs. This may require production changes by Manufacturers using this construction detail.

UB-14(c) Addition Added paragraph UB-14(c) to specify values of "E" to be used when calculating the required thickness of seamless shells and heads in brazed construction. Previous Code rules referenced UW-12 for determining the value of "E", but did not address brazed construction using seamlessparts.

UB-42 Errata UB-42, inserted the word "has" before the word "been" at the beginning of line 6.

Figure UCS-66.2 Errata Figure UCS-66.2, Change "thickness" to "thicknesses"

Table UCS-56, P-No.4 Revision The required minimum PWHT temperature for P-No. 4 materials has been increased to 1200oF,to improve tempering of the heat affected zones. Research has shown that effective transformation of the HAZ only occurs when a minimum PWHT of 1200oF is applied. This action brings Section VIII in alignment with Sections I and B31.1.

Table UCS-56, P-No.10B Revision The required minimum PWHT temperature for P-No. 10B materials has been increased to 1200oF. It is believed that this change was made in error, and should not be applied to Code construction without further assistance from the Codes and Standards Technical Staff.

Table UCS-56, P-No.1 Revision The required minimum PWHT temperature for P-No. 1 materials has been increased to 1200oF.It is believed that this change was made in error, and should not be applied to Code constructionwithout further assistance from the Codes and Standards Technical Staff.

UCS-79(d)(4) Revision UCS-79(d)(4) was revised, clarifying the limit of 10% on reduction in thickness due to forming applies to any location where extreme fiber elongation exceeds 5%. Exceeding the thickness reduction limit in these locations requires strain relieving heat treatment to be performed after cold forming. The following intent interpretation was also published as part of this action:Question: Is it the intent of the Committee, when applying the rules of UCS-79(d) that the reduction by cold forming from the as rolled thickness as limited by UCS-79(d)(4) is to be determined at the same location where the extreme fiber elongation exceeds 5%? Reply: Yes

Table UNF-23.3, UNS N08825

Addition Table UNF-23.3 was revised to add the large forging product form SB-564 for alloy UNS N08825. Several product forms of UNS N08825 were previously listed in Table UNF-23.3, butthe large-forging product form covered by SB-564 was not.

Table UNF-23.3, UNS R31233

Addition Approved the inclusion of UNS R31233 into Table UNF-23.3 of SC VIII-1 as well as the addition of weld and heat treatment information in para. (e) of Section VIII-1 UNF-19 and para.(f) of UNF-56.


Addition Revised Table UNF-23.3 to add UNS N08367 under SB-366


Addition Revised Table UNF-23.3 to adopt UNS N06686 under SB-564, SB-574, SB-575, SB-619, & SB-622.


Addition Revised Table UCS-23.3 to adopt UNS N06200 under SB-366, SB-564, SB-574, SB-575, SB-619, SB-622.

Table UNF-23.3, SB-462

Addition Adopted B 462-02 as SB-462. Added SB-462 to Table UNF-23.3, with alloys UNS N06022, N06030, N06200, N10276, N10665, and N10675.


Revision Removed UNS N08366 (AL6X) from specifications SB-675, SB-676, SB-688, SB-690, and SB-691, since this alloy is no longer produced. UNS N08367 (AL6XN) is the current form of this alloy.

UNF-19(e) Addition New paragraph UNF-19(e) restricts welding processes to GTAW and GMAW when welding UNS N06230 materials using filler metals of the same chemical composition. Research has uncovered a tendency for microfissures to form when using less restrictive welding techniques.

UNF-19(f) & UNF-56(f) Addition Added new paragraph UNF-19(f) to address requirements for filler metal selection and testing of welding procedures when joining SB-815 or SB-818, UNS R31233. Also added new paragraph UNF-56(f) to address PWHT requirements for these materials. These changes are part of the action to incorporate Code Case 2121.

UNF-19(d) Errata UNF-19(d) revise SI units from "51 mm" to "12.7 mm" (this change was made as shown, but requires further correction due to metrication guidelines)

Table UHA-23, SA-995 Revision Cast duplex stainless steel CD4MCu has been replaced by CD4MCuN, and has been moved and redesignated as Gr. 1B, along with CE8MN, which was redesignated as Gr. 2A, to SA-995.

Part UHX Errata Numerous errors were made to Part UHX in the 2003 Addenda. This item was opened to correct these errors.

UHX-4(e)(1) Revision UHX-4(e)(1) required tube wall thickness under internal and external pressure to comply with UG-31. This was considered misleading, since additional requirements for tubes are found in UG-8 as well. Consequently, UHX-4(e)(1) has been deleted and UHX-4(e)(2) & (3) renumbered accordingly. The general reference to Subsection A in UHX-4(a) "turns on" all applicable requirements for tubes.

UHX-11 thru UHX-14 & UHX-20

Revision -Revised UHX-11 to account for designs where tubes are welded to the back side of the tubesheet, and not extending through the tubesheet; and for multiple pass partitions within a single exchanger tube bundle. -Revised UHX-12 to clarify the process for determining the yield strength for materials. -Relocated rules for determining the effect of radial differential thermal expansion at the tubesheet on shell and/or channel joint for integral construction to UHX-13.8 and UHX-14.6, now requiring these analyses be performed only in critical high pressure and high temperature applications. -Resequencing of operations delays calculating the seven load cases until later in the design procedure, reducing the number of calculations to be performed.

Part ULW & Appendix 29

Revision Manufacturers are no longer building these strip-wound vessels, and for this reason Section VIIItook action to delete the following references to rules for their construction:-Sketches (e), (e-1), and (e-2) from Figure ULW-2.1-Paragraph ULW-17(b)(3)-Sketches (h) and (h-1), depiction of interlocking strip, and Note (3) from Figure ULW-17.4-Paragraph ULW-76(c), and redesignate the following subparagraphs accordingly-Appendix 29 in its entirety

Table ULT-23 Revision Approved metricated values for Table ULT-23.

Appendix 1-4 Errata 1-4(f)(1), changed "0002" to "0.002", and "lager" to "larger"1-4(f)(1)(f), changed "Sy" to Se"1-4(h) &(i), changed "Pek" to "Pck"

Appendix 10 Revision The revisions to Appendix 10 clarify that the Certified Individual and the Authorized Representative signing the Manufacturer's Data Reports may be the same person.

Appendix 13, 13-4(j)(2) Revision Revised 13-4(j)(2) to clarify that the intended minimum thickness "t" to be used when perfoming the reinforcement calculations referenced in UG-39 is determined by 13-4(b), including membrane and bending stress considerations.

Appendix 14, 14-1(a) & 14-3(b)(2)

Revision Added the last sentence to paragraph 14-1(a) and revised the first sentence ot 14-3(b)(2) to provide directions for applying Appendix requirements to flat heads with nozzles attached by nonintegral welds (such as fillet and partial penetration welds).

Appendix 17, 17-2(c)(1) Revision Deleted 17-2(c)(1), redesignating (c)(2) as simply (c), removing prohibitions against using TableUCS-23 materials in dimpled or embossed vessel construction with an intended MDMT colder than -20F unless specifically exempted. Exemption paragraphs previously appearing in 17-2(c)(1) was incomplete, and required revision. However, existing rules of Part UCS are adequate, no further restrictions for carbon steels in Appendix 17 construction are necessary.

Appendix 20 Errata Appendix 20, revised reference in third paragraph of 20-2 from Figure "5" to Figure "4" of SA-370

Appendix 23, 23-4(a)(2), 23-3(b)

Revision Revised 23-4(a)(2) to allow the design temperature of finned copper tubes to be as great as the maximum temperature shown on the external pressure chart when the tubes have been annealed after finning. 23-3(b) was revised to indicate the F factor used to adjust allowable stresses for temperature in the equation used to determine MAWP now applies equally to titanium, copper and copper alloy tubes.

Appendix 26 Revision Appendix 26 was rewritten, expanding its scope to include toroidal bellows and multiple layer bellows. New rules apply EJMA formulae for stress calculations; fatigue design is based on B31.3 with design margins from VIII-2 Appendix 6 (2.6 on cycles & 1.25 on stress) to develop to the design fatigue curve. BELLOWS MANUFACTURERS SHOULD TAKE NOTE OF THESE REVISIONS BEFORE THE MANDATORY IMPLEMENTATION DATE OF 3/31/2005.

Appendix 26 Revision Editorial changes have been made to Appendix 26. The more noteworthy changes include:-Clarifications and better consistency between Clauses-Revised notations for consistency with EJMA : K changed to Kb , nu changed to nub-Addition of notations Ef , Er , Lf which were previously missing.

Appendix 32 Errata 32-2(a), changed "of" to "or" in line 432-4(e), changed "depths" to "depth" in line 532-6(e), changed "mid" to "and" in line 232-6(h), changed "mid" to "and" in line 3

Appendix 5 Revision Appendix 5 was found to be inadequate in addressing cyclic load conditions. A new paragraph 5-1(d) was added to notify Code users that cyclic loading conditions are not addressed in Appendix 5, sending them to U-2(g). The former paragraph 5-1(d) has been redesignated as 5-1(e). 5-3 has been revised to delete cyclic design calculation requirements.

Appendix 5, 5-6 Revision Revised 5-6 to ensure essential expansion joint design and service information is included on theManufacturer’s Data Report, and to remove redundancies between UG-116(h) and 5-6.

Appendix A Errata Appendix A, deleted references to UW-20 in A-1(a) and Table A-2 Note (4), and replaced themwith references to UHX-15.

Appendix FF Addition This is a new NonMandatory Appendix on the subject of Quick Opening Closures, providing guidance on design considerations, fail-safe behavior, installation, cleanliness, operating and other issues associated with these devices.

Appendix GG Addition New Appendix GG has been added to Section VIII-1 to provide the guidelines used in Metricating the Code. These guidelines are to be applied as necessary when performing conversions other than those prepared by the Code Committees.





Appendix W, Note 24 Revision Note 24 of Appendix W has been revised to indicate that the joint efficiency may come from UW-12 as well as Table UW-12. The U-1A Manufacturer's Data Report was also revised to permit indication of a numerical value for circumferential joint efficiency in the shell in a new blank provided for this purpose.



Code Case 1750-18 Errata Code Case 1750-18, revised lowest permissible design temperature for SA-352,Grade LCC from "55F" to "-55F"

Code Case 2046-1 Revision When the minimum required test pressure is equal to the maximum permitted test pressure, and the actual pressure varies by more than 1 or 2 psi, then the Manufacturer could be in violation of the requirements of the Code Case. The proposed changes will allow for tolerance without sacrificing the integrity test of the vessel. Variations may be due to accuracy of the device used to measure the pressure.

Code Case 2235 Revision Some of the Nomenclature of Figure 5 in the Code Case was revised to correct some inaccurate definitions.

Code Case 2240-1 Revision Revised CC 2240-1 to change the P-No. of the subject material from P-No. 44 to P-No. 43, to align with other P-No. changes in nickel alloys in QW/QB-422 of Section IX.

AG-150.1, AD-623 Revision Adopted ASME B16.9-2001 and deleted ASME 16.28, “Wrought Steel Buttwelding Short Radius Elbows and Returns” from Table AG-150.1, as this specification has been withdrawn by the B16 Committee and its provisions incorporated into ASME B16.9, “Factory Made Wrought Buttwelding Fittings”. The deletion of ASME B16.28 makes AD-623 unnecessary, so it has been deleted.

AG-300 & AG-301.1(d) Revision Revised AG-300 and AG-301.1(d) to more clearly state that the Code Edition year and Addenda date of Section VIII, Division 2 appearing on the User's Design Specification and the Manufacturer's Design Report shall be the same as those appearing on the Manufacturer's Data Report.

AF-210.1(b) Revision AF-210.1(b) was revised to clarify that welding performed by subcontracted welders must take place at the address on the Certificate of Authorization or the final installation site. Though thispractice was not common in Section VIII, Division 2, and the Division 1 Interpretations supporting it did not specifically apply to Division 2, the possibility of applying it to Division 2 remained. These actions eliminate this possibility.

KD-231, Figure KD-230 Revision Revised KD-231 and Figure KD-230 to eliminate the knock down factor previously assigned to materials with high Sy/Su ratios. The knock down factor has been mooted by additional requirements restricting the use of linear elastic plastic analysis to small diameter ratios less than 1.5.

KD-240, KD-251, KD-1254

Revision Revised KD-240(a) & (b) to decrease the design margin for plastic collapse from 2.0 to 1.732, for greater consistancy with other design margins in Section VIII, Divisions 2 and 3. Revised theformulas of KD-251 and KD-1254 to apply this design margin reduction directly to associated calculations. This action maintains the viability of Section VIII, Division 3 for vessel designs affected by this margin.

KD-301 Revision The references to specific fatigue curves has been deleted, as these references are obsolete.

Foreword Revision Revised the last paragraph of the Foreword to require that when local customary units are to be shown on the nameplate, they should also be shown in parenthesis on the Manufacturer’s Data Report.

IWA-2210 through 2216 Errata Deleted revisions to IWA-2210 through IWA-2216 that were inadvertently made with the 2002Addenda

IWA-2221, Case N-685

Revision Revised IWA-2221 to establish the minimum lighting requirements for surface examinations using non fluorescent techniques at 50 fc. These requirements supersede the lighting requirements given in Section V, Articles 6 & 7. Case N-685 allows immediate use of these provisions.

IWA-4120(b)(4) Revision Revised IWA-4120(b)(4) to eliminate the <1/2 thickness exemption limit for orifice plates, making orifice plates of all thickness exempt from the requirements of Article IWA-4000 when held in place mechanically (not welded), and connecting piping of the same design pressure.

IWA-4131.1(a)(1) Errata IWA-4131.1(a)(1), Footnote 6, deleted "applicable" from in front of "ASME B36.10" and changed "ASME B36.10" to "ASME B36.10M"

IWB-1220, IWC-1221, IWC-1222 & IWD-1220

Revision Revised IWB-1220, IWC-1221, IWC-1222 & IWD-1220 for better consistency between the Subsections. Additionally, clarified that primary and secondary sides of heat exchangers are to be handled separately, and that components connected by exempt piping segments are also exempt.

IWB-3523 Revision Revised IWB-3522 to provide alternative examinations requirements for PWR Control Rod Drive (CRD) Housing Welds and add examination requirements for In-Core-Instrumentation (ICI) Housing welds greater than NPS 2. Added the ICI weld requirements to Table IWB-2500-1, Category B-0, and revised Figure IWB-2500-18 to address these added requirements.

IWB-3660, Case N-694 Revision Added new paragraph IWB-3660 and Case N-694 to expand coverage of flaw evaluation methods and acceptance criteria for both upper and lower head penetrations. The flaw locationsrelative to the pressure boundary have been clarified, to ensure proper interpretation of the Acceptance Criteria. Figure IWB-3662-1 and Table IWB-3663-1 have been added as associated actions.

Table IWB-2500-1 & Case N-652

Revision Revised Table IWB-2500-1 & Case N-652 to clarify Examination Category B-G-1. The locationof references to notes (3) and (4) made in the 2002 Addenda are being moved to ensure that the Cat. B-G-1 bolting of all steam generators is examined, even if the steam generator welds are notselected for examination. This clarifies that the notes were not intended to include steam generators with other heat exchangers. Similar changes were made to Code Case N-652.

Table IWB-2500-1 Errata Table IWB-2500-1, changed "WIB-3518" to "IWB-3518" as seen in the line entry for B12.30 inthe "Acceptance Standard" columnTable IWB-2500-1, added references to Footnote 5 in the headings for both columns under "Extent and Frequency of Examination"Table IWB-2500-1, deleted references to Footnote 4 from the line entries for "B6.70", "B6.100", "B6.130", "B6.160", "B6.190", and "B6.220"

Revision Revised footnote 4 of Tables IWB/C-2500-1 for Examination Categories B-K and C-C and footnote 3 of Table IWD-2500-1 for Examination Category D-A to clarify the examination requirements. For single vessels, only one attachment need be examined. For multiple vessels with common attachments, the examination is required to be performed on a single attachment under continuous load during plant operation, or if none is so loaded, one with intermittent loads.

IWA-2430 Errata IWC-2430, corrected the spelling of "parts"

IWD-5200 Revision Revised IWD-5200 by deleting IWD-5200(a)(1) & (2). Moved the test boundary requirements previously contained in IWD-5240 into IWD-5222. Moved the requirements previously contained in IWD-5222 into IWD-5230, and the requirements previously contained in IWD-5230 into IWD-5240. Paragraph references from IWA paragraph were changed to reflect these revisions. These actions complete the incorporation of Case N-498-1, and aligns the requirements more closely to those in Part IWC.

Subpart/Table: IWC


Subpart/Table: IWD




IWE-3511.3 Revision Revised IWE 3511.3 to expand applicability of the examination requirements to metallic shell and penetration liners of Class CC pressure retaining components.

IWF-2430 Revision IWF-2430(a), (c), and (d) were revised to clarify that when flaws exceeding the acceptance criteria are identified during outage examinations, the required additional examinations of IWF-2430 are to be conducted during the same outage, and not postponed until a subsequent outage. This makes Part IWF more consistent with Parts IWB, IWC, and IWD for these examinations.

Appendix VII-4120 Revision Revised VII-4121, VII-4122, and VII-4123 and Note (b) of Table VII-4110-1 to eliminate the minimum nuclear examination experience requirements for UT Level III examiners. The combination of non-nuclear experience and the performance demonstration rules of Appendix VIII make nuclear experience unnecessary.

Appendix VIII, Supplement 10

Revision Revised Appendix VIII, Supplement 10 to address the differences in qualification between OD and ID examinations. Added Table VIII-S10-1, providing acceptance criteria for personnel performance demonstrations. Also included are provisions for use of alternative flaw mechanisms and improvements in the performance demonstrations gained from several years experience. Implementing Code Case N-695 was approved to allow immediate use of these provisions.

Appendix VIII, Supplement 14

Addition Added a new Supplement 14 to Appendix VIII, providing a coordinated implementation of the fundamental qualifications required for the typical examinations performed from the ID of PWR nozzles. This supplement uses the more technically stringent Supplement 10 qualification as a base, and adds a limited number of Supplement 2 and Supplement 3 samples. Implementing Code Case N-696 allows immediate use of these provisions.

Appendix H Errata H-4410(a), revised the formula for "I'm", moving the closing bracket forward to just before the division bar.H-4410(c), revised the formula to enclose the first rational expression into parentheses, and remove the division bar prior to the last parenthetical expression.H-4420, substantially revised the formula in the first nomenclature entry.H-4520, substantially revised the formula in the first nomenclature entry, changed "K1 " in nomenclature to "KI ", added division bar between first two parenthetical expressions in formula for "fc"
