EditorialDear Readers,

Welcome to the Spring 2011 issue of PetroChem

E-ssentials, the quarterly e-newsletter of PetroChem

Inspection Services, a subsidiary of TÜV SÜD America.

An important compliance consideration in the petroleum

and chemical industries is the inspection of storage tanks and

pipelines. So, in this second issue of PetroChem E-ssentials,

our editorial coverage focuses on inspection procedures and

techniques for these important infrastructure elements.

American Petroleum Institute (API) Standard 653 is the

key industry standard for the inspection of storage tanks.

However, many tank operators are only partially familiar

with the provisions of the standard, especially the mandated

inspection requirements. Our lead article, “Inspection

Requirements of API-653,” provides an overview of the key

inspection aspects covered in this important document.

Inspecting the integrity of piping that is buried or otherwise

inaccessible is a common industry challenge. In our second

article, “Guided Wave Inspection: Selected Case Studies,”

we review three instances in which PetroChem inspectors

used guided wave inspection technology to assess pipeline

integrity, an approach that saved our customers both time

and expense.

Inspecting buried piping is always challenging and should

involve various non-destructive testing (NDT) techniques

suitable to the situation at hand. Each inspection technology

has its unique characteristics and advantages. In our article

“Options for Inspecting Buried Plant Piping,” we identify and

discuss a number of NDT options, and how these techniques

can be used individually or collectively to provide the most

accurate assessment of buried piping.

We round out this issue of PetroChem E-ssentials with

a lineup of 2011 industry trade shows, conferences, and

other events and training that may be of interest to our

readers, as well as brief highlights from PetroChem’s March

golf charitable event which raised $4,000 for children with

cancer.

Finally, although we work with companies around the

world, our customers seldom have the opportunity to visit

our facilities and meet the local, technical staff that supports

efforts in the field. We’ll be hosting a series of regional

Open House events into Fall at various PetroChem locations,

featuring presentations and hands-on demonstrations on a

wide range of topics. Read the article in this issue for more

information, or register online today. We hope you can join

us!

Inspection Requirements of API-653

American Petroleum Institute (API) Standard 653 “Tank Inspection, Repair, Alteration, and Reconstruction” provides minimum requirements for the integrity of steel tanks, and identifies considerations regarding inspection, repair, alteration, relocation, and reconstruction. The scope of the standard is limited to the tank foundation, and the bottom, shell, structure, and roof of the tank, as well as tank attachments, such as nozzles.

Section 6 of API-653 covers the inspection requirements for aboveground storage tanks. The performance of mandated tank inspections under the standard is limited to those professionals who have been certified by the API, consistent with the technical requirements of the standard. However, tank owner/operators seeking to develop or verify their tank integrity maintenance programs will benefit from a basic understanding of API-653’s inspection requirements.

Below is a summary of the key inspection requirements as found in Section 6 of the standard.

Inspection Frequency: API-653 provides an extensive list of factors to be considered in determining appropriate inspection intervals for in-service tanks. Some of the factors include the location of the tank, the materials used in the tank’s construction, the nature of the product stored in the tank, the existence of corrosion prevention systems, the results of visual maintenance checks, and conditions found during previous inspections.

Inspections from Outside the Tank: According to the standard, all tanks must receive an external inspection by an authorized inspector at least once

every five years, or more frequently depending on the rate of tank shell corrosion. The thickness of the tank shell and the rate of shell corrosion can be determined through the use of ultrasonic thickness measurements. In addition to the mandated inspection, owner/operators should routinely conduct a visual inspection of the tank from the ground.

Internal Inspections: API-653 generally requires that all newly installed tanks receive an internal inspection within 10 years of their entry into service. However, the maximum initial internal inspection interval may extend up to 25 years based on the completion of a risk-based inspection (RBI) assessment and the types of leak prevention, detection or containment safeguards that have been installed. Subsequent internal inspections are based on the rate of corrosion, with the duration extending from 20 to 30 years, depending on the method used to assess the rate of corrosion.

Determining Bottom Thickness: In those instances where the construction of the tank allows external access to the tank bottom, an external inspection to measure tank bottom thickness is permitted. However, in such cases, the owner/operator should consider other maintenance items in determining the appropriate intervals for internal tank inspection, and should document the rationale for this practice in the permanent record for the tank.

Preparing for Internal Inspections: The standard mandates that all inspection work be conducted in a manner that assures the safety and health of inspection personnel and prevents workplace property damage. Section 1.4 of API-653 requires the development of safety procedures consistent with API 2009, API 2015, API 2016, and API 2217A. In addition, special safety procedures may need to be developed for certain activities, and all safety procedures must comply with the provisions of any federal or state safety regulations dealing with other relevant factors, including requirements dealing with confined spaces.

TÜV SÜD E-ssent ials Vol. 2 April 2011Page 3

Inspection Checklist: Annex C of API-653 contains two comprehensive sample checklists covering the internal and external inspection of tanks, one for in-service tanks and one for out-of-service tanks. The checklists can aid the tank owner/operator in developing a tank inspection assessment schedule, and can facilitate the recording of findings from the inspection.

Record Keeping: The tank owner/operator is required to maintain three types of records, as follows: 1) construction records, including drawings and specifications, and any results of material tests and analyses conducted; 2) inspection records, including a record of all examinations and tests, the condition of the parts inspected, and corrosion rate and interval calculations; and 3) records of any repairs and alterations, and any replacements and service changes made to the tank.

Reporting: Inspectors are required to prepare a written report, including any recommendations. The owner/operator of the tank must retain a copy of the report and recommendations, and document any actions taken as a result of inspector recommendations, for the life of the tank. Local authorities may have additional reporting and record-keeping requirements for tank inspections.

A complete copy of API Standard 653 is available for viewing and purchase on the API website, www.api.org/standards.

Guided Wave Inspection: Selected Case Studies

Guided wave inspection can be an effective method for evaluating the integrity of pipeline that is inaccessible for other testing methods, such as ultrasonic testing (UT). This article will review three separate instances where guided wave inspection techniques were used to screen long lengths of pipework from a single location using proprietary screeing equipment (the WavemakerTM Pipe Screening System).

CASE 1: EXTENDED LENGTH PIPESThe photograph in Figure 1 shows an extended length of 3” uncoated pipeline lying directly on the ground and carrying light crude oil. A visual inspection of the pipe was difficult due to the pipe’s length and vegetation coverage, but the general surface condition of the pipe appeared to be good. In this instance, a single test screened 130 meters of the pipeline while in service. The photo identifies the location of the guided wave inspection test equipment, as well as the location where major defects were detected.

Figure 2 shows the computerized results of the guided wave inspection for the section of the pipe in the photograph. A minor corrosion patch was found and has been marked +F1. A major defect was found close the weld marked +F2. The pipe section after this weld, marked +F3, shows very high attenuation, an indication of heavy general corrosion. This finding was later confirmed using standard UT measurements As a result of this test, the client was able to limit follow-up inspection and maintenance to the areas of pipe which were found to be defective, considerably reducing the time and expense associated with these activities.

CASE 2: EMBEDDED PIPESWall penetrations are a common feature within oil and chemical plants where walls are built to control spillage of products and possible flooding. Walls of this type are between 150 and 400mm thick and are usually made from concrete. There are two common types, 'built-in' where the pipe is simply cemented into the wall during construction, and 'sleeved' where a larger diameter sleeve is cemented into the wall, providing a conduit for the pipe.

The pipe region within and around a wall penetration is susceptible to corrosion but is inaccessible for visual and conventional UT. As a compromise, UT measurements are often taken at a single point on the pipe near the penetration and compared over time to give a general indication of pipe condition. However, this method cannot give any indication of the condition of the pipe within the wall.

light crude

Guided wave inspection offers a solution to this problem by inspecting the pipe within the penetration and its surroundings for corrosion and other defects from a single, convenient location some distance away from the wall.

The photograph in Figure 3 shows two typical 'built-in' wall penetrations within a petrochemical plant. The UT testing points for the pipes are indicated. The standard UT measurements and visual inspection suggested that no corrosion was present in either pipe.

Figure 4 shows the computerized result of the guided wave inspection of pipe A. The location

of the wall is indicated by the shaded region at the top of the diagram. The entrance to the wall is labeled F1. No reflected signals were detected from the entrance or from within the wall. This indicates that no significant defects are present.

Figure 5 shows the computerized result of the guided wave inspection for pipe B. Again, the entrance to the wall is labeled F1. A large reflected signal was detected from the area within the wall. This signal also has significant asymmetric content (indicated by the red trace). This result indicates that there are significant defects such as corrosion within the wall penetration.

For comparison purposes, Figure 6 shows the computerized result of a guided wave inspection of a pipe which passes through a sleeved wall penetration. A large and asymmetric signal was detected from the entrance to the sleeve which indicates the presence of a significant defect.

The defect identified as a result of the inspection was visually verified by removing the weather seal from the end of the sleeve. The photograph in Figure 7 shows the area of severe localized corrosion, with up to 50% wall loss in some areas.

CASE 3: DIFFICULT-TO-ACCESS PIPINGIn many cases, sections of pipework within petrochemical plants are located many meters above the ground, where they cross roadways or other pipe racks. These sections of pipe are more difficult and costly to inspect using conventional techniques, since temporary scaffolding is required to gain access to them. Guided wave inspection techniques are ideally suited for these screening challenges, allowing for the screening of long lengths of overhead pipework from a single, easy-to-access location.

In this case, testing was conducted on a 3-inch pipe in service. Visual inspection of the pipe was difficult due to its length and height from the ground, but the general surface condition of the pipe was lightly corroded.

The photograph in Figure 8 shows the pipe under test. The pipe initially runs at ground level and then turns upwards through a 90-degree cast bend. Then, there is a 5-meter long vertical section before the pipe turns back to the horizontal through another 90-degree cast bend.

The test equipment is mounted to the vertical section of pipe, just above the lower bend. From this location it is possible to test not only the vertical section of pipe but also around the bend and along the horizontal section. The total range which can be tested depends on general pipe condition and coatings, but more than 20 meters were tested in each direction in this case.

Figure 9 shows the computerized result of a guided wave inspection of this piping. The result indicates that the overall condition of the pipe is good, but that there is a short section of concerned (labeled-F1). As a result of this test, the client was able to limit follow-up inspection and maintenance to those areas of the pipe that were found to be defective. This considerably reduces the time and cost of these activities.

Options for Inspecting Buried Plant Piping

Corrosion at petrochemical and refining facilities will always be a major concern for piping integrity. Underground piping not only exacerbates the general external corrosion of the piping, it also makes the inspection efforts required to ensure the safe and reliable operation of the buried segment more tedious and difficult.

A commonly used method in the industry today of removing a line from service to perform an in-line inspection or hydrotest does not always prove sustainable or cost-effective. Further, since the primary costs when evaluating buried piping is attributed to the time spent on excavation, minimizing the amount of excavations is an important goal in the industry.

There are numerous methods that can be used to inspect buried piping and to minimize the amount of excavation that is necessary, including advanced non-destructive testing (NDT) techniques. Unfortunately, many of these methods are overlooked due to lack of knowledge within the industry. Here is a brief list of the various types of NDT inspection methods that are available for underground piping.

Direct Assessment Methods: Originally developed for use with natural gas transmission pipelines, direct assessment methods include external corrosion direct assessment (ECDA) and internal corrosion direct assessment (ICDA), and allow for the efficient identification of areas of probably concern and/or high consequence.

Above Ground Methods: Above ground methods for inspecting buried piping from above grade include close interval potential survey (CIPS), direct current voltage gradient (DCVG), and alternating current voltage gradient (ACVG). CIPS examines the pipe to soil potential, while DCVG and ACVG measure voltage gradient along the buried segment.

Direct Inspection Methods: Guided wave ultrasonics is a minimal excavation method that allows for the inspection of lengths of piping from a single test position. It works by generating low-frequency guided waves, and transmitting them down the length of the piping. While both internal and external metal losses are detected, guided wave ultrasonics cannot distinguish between the two. Further, pipe coating and soil conditions can affect the result.

Automated ultrasonic testing (AUT), another direct inspection method, is a quantitative method for obtaining wall thickness measurements on piping in areas of pitting or general corrosion. The technology uses digitally controlled ultrasonic scanners to acquire data, and specialized software for data processing and display. AUT is generally an ideal method for anomaly verification discovered through the use of other quantitative methods.

OTHER INSPECTION METHODSAlternating current field measurement (ACFM) uses an alternating current field to detect and size pipeline cracks. The current field is disturbed when a crack is detected, thereby revealing the crack location. ACFM will work through most pipeline coatings with minimal surface preparation.

The recognition of the appropriate methods and tools that can be used to detect corrosion of buried piping can lead to accurate inspections that can be achieved without excessive cost. However, no one approach or method can provide all of the necessary data when inspecting buried piping. Instead, a comprehensive testing strategy that includes different, but complementary, techniques is the best approach.

Readers interested in learning more about this subject can read the article, “Inspecting Underground Piping,” written by Brant Shields, Technical Manager of PetroChem’s advanced inspection services, which was published in the February 2011 issue of Chemical Engineering. n
