1.0 PURPOSE

This design basis deals with the subject of Identification of Stress Critical pipelines andpreparation of Critical line list. This procedure also defines the minimum requirements forperforming stress analysis, design and location of spring, support and extent of systemanalysis with the extent of documentation required for flexibility analysis

Purpose of piping stress analysis is to ensure:

Safety of piping and piping components

Safety of connected equipment and supporting structure

Piping deflections are within the limits

2.0 SCOPE

This specification covers the supply of engineering services to perform a complete piping andpipe support analysis for new and modified piping systems for HPCL Mumbai Refinery for itsDHT Project.

3.0 DEFINITIONS

3.1 CRITICAL LINES / CRITICAL LINE LIST

Critical lines or Critical Line List as referred to in this procedure relates to Piping StressCritical Lines and does not include or refer to process critical lines.

3.2 STRESS ANALYSIS TEMPERATURE

Stress Analysis Temperature refers to either Maximum Operating Temperature or Steam-out temperature / hot Nitrogen purging temperature of the lines under review whichever is

higher. In absence of the above values, it refers to the Design Temperature of the line underreview. The Line List should be strictly followed in obtaining the above temperature

3.3 DESIGN PRESSURE

Design Pressure refers to the Design Pressure of the line under review as indicated on theLine List. Design Pressure is as defined in clause 301.2 of ASME B 31.3.

3.4 TEMPERATURE FOR FLEXIBILITY ANALYSIS

The temperature to be used for the flexibility analysis shall be taken as the maximum /minimum temperature which the pipe will see under any combination of different normal /abnormal operating conditions, as defined in clause 301.3 of ASME B 31.3. Where piping isexposed to direct sunlight, solar radiation temperature of 70

0C is considered in establishing

the maximum temperature of piping. Even, for non-critical piping exposed to direct sunlight onpipe rack or elsewhere, expansion loops, wherever essential, are provided to take care of

pipe movements resulting from piping skin temperature due to solar radiation.

In general, unless there is a difference of more than 500

C between working temperature andthe design temperature, the design temperature should be taken as Flexibility temperature.Ifthe difference is higher than 50

0C the stress analysis temperature is needed to be decided in

consultation with process Licensor/Group.

The temperature under Fire Condition are not considered for stress analysis except for flarelines.

Ambient Temperature shall be considered as 21 C. the assumed piping installationtemperature. The displacement stress range from this installation temperature to theminimum recorded ambient temperature of 12

0C being less than the same from installation

44LK 5100 Sheet 4 of 15

temperature to the maximum operating temperature of hot piping in most cases the latergoverns as per clause 319.2.3 of ASME B 31.3.

4.0 METHOD OF ANALYSIS

A line is selected and listed as a Critical Line provided it falls under any one of thecategories defined in Attachment 10.1 and is intended to include the specialrequirements of Piping Stress Engineer. It is hence defined as any line for which aflexibility review is required or where pipe supporting is deemed to be critical and needsreview by a Stress Engineer.Hence all lines following outside the categorization aredeemed non critical which can be reviewed using nomographs manual calculation and/onvisual analysis.

All lines in this list essentially need a formal computer analysis with a trunioncalculation,Flange leakage calculation and nozzle load calculation as required,Very largediameter (thin walled)pipes and ducts need special design consideration which should behighlighted.

4.1 LINES DEEMED TO BE SUPPORT CRITICAL

Lines subjected to two-phase flow

Cross country pipelines.

Lines with pipe thickness Sch 160 or greater

Lines DN 400 and above with pipe thickness less than 8 mm.

Lines DN 250 and above with corrosion allowance 3 mm and above

Lines with high concentrated loads such as heavy valves or fittings etc.

Lines downstream of Relief Valve / letdown Control Valves / bursting (rupture) discs.

connecting to vent or flare systems or discharging to atmosphere.Liquid Blow down Lines

Lined pipes

Non-metallic pipes

4.2 LINES NEEDING DYNAMIC ANALYSIS

There are instances where in the frequency of the applied load is comparable to thenatural frequency of the piping system. Such systems tend to store the energy andrelease it according to certain scientific laws. Such a system is dynamic in nature and thestudy of the response of such a system is referred to as Dynamic Analysis. Examples ofsuch kind of systems are Relief Valve discharge lines, Safety valves / rupture discs, waterhammer and surge in pipelines, two phase slug flow in pipelines, reciprocating pumps andcompressor piping, submarine piping,pipelines subjected to earthquake of largemagnitude etc.

4.3 SPECIAL PIPING

Special piping forming part of reformer tubes, heater internal piping, etc. are treated asproprietary piping and nozzle loading at the Interface connections are to be co-ordinatedwith vendor.

4.4 Pipelines which will require seismic analysis,Refer to Attachment 10.2

The list shall reflect analysis status of line that includes its input received date from design& output handover date to design and specific remark if any.

5.2 LINES AFFECTING THE FLEXIBILITY OF CRITICAL LINES

a) Non-critical Lines found to affect the flexibility of critical lines which have not beenincluded during the initial review are subsequently added to the Critical Line List.

b) Non-critical Lines on which advice may be sought by the Lead Piping Engineer are

not normally entered into the Critical Line List but covered verbally, or by amemorandum if a record is required.

c) All non critical lines (having size more than half of main run size) that tie into criticallines should be considered as critical upto first anchor if they have significant effecton main line flexibility.

6.0 PIPE STRESS ANALYSES AND SUPPORTING

6.1 Piping support Criteria and General Guidelines :

Categorization for Seismic analysis

Definition: Plant Piping located in earthquake prone areas of the country will experience accelerationsimparted through foundations, structures and various equipment. Criticai piping {toxic, flammable, highpressure, high temperature, emergency) which must remain leak;tight or operable (deliver, control orshutoff flow) during or following the event, have nozzle loads within vendor's set limits, have minimumsway to avoid impact or interference with adjacent equipment / pipes / structures need seismic analysis todetermine the effects.Based on Indian code IS 1893-2002, areas falling under Zones IV and V are categorized as "Severe"while Zones II and III are prone to earthquakes of "Moderate" or "Low" intensity. The IS 1893-2002guidelines for BUILDINGS to be seismically designed are as beiow;

For regular buildings, if the building height is greater than 40 m in Zones IV and V or greater than90 m in Zone II and III ;

For irregular buildings, if height is more than 12 m in Zones IV and V and more than 40 m in

Zones II and III,

Method: Process Plants normally fall within the irregular building category and hence the piping andequipment are to be analysed accordingly. To get realistic results, it is essential that seismic analysis forpiping be carried out using the Dynamic analysis method viz. Time History method or Modal ResponseSpectrum method. Piping connected to tail columns/vessels, chimneys and any slender structure shouldpreferably be analysed using dynamic analysis. Long-run piping on tall slender structures (such as flarepiping on trestles) should be analysed using composite analysis. For toxic/lethal piping systems, theseismic anchor movements also need to be imposed during the dynamic analysis. However forsimplification's sake wherever dynamic analysis is not mandatory by the client or the responsespectra cannot be derived from data available, seismic design can be done using the EquivalentStatic (static coefficient) method.

The seismic accelerations, response spectra and anchor movement values are to be obtained from theCivil Group.For seismic analysis, earthquake loadings shall not be considered to act simultaneously with wind. Also itis to be noted that cross-country pipelines, buried piping & piping for nuclear installations will needrigorous analysis and the selection criteria below does not apply. Refer LWI 220 for explanatorytechniques for seismic design of piping systems (under development)

Selection: With due considerations to fluid criticality and intended operation, in order to assess maximumimpact it is recommended that only critical piping with higher sizes (i.e. higher mass and/or at higherelevations which in turn reflects as higher force) be seismicaiiy computer analysed. Since not explicit inIndian codes, following guidelines are a conservative selection.

All critical piping systems aboveground with a weight (self+fluid+insuiation) greater than 410kg/m (corresponds to a 24" STD schedule water filled pipe).

All critical piping systems above ground with any portion routed at a height (height as per theabove IS 1893 building categorization) with a weight greater than 210 kg/m (corresponds to a 16"STD schedule water filled pipe). Give due consideration to piping connected to tall equipment &piping routed on tall slender structures.

All emergency service critical piping systems above ground with any portion routed at orgreater than 25m with a weight greater than 110 kg/m (corresponds to a 10" STD schedulewater filled pipe).

Smaller critical lines (3" to 10") routed above 10 m elevation need to be seismically analysedprovided the wind load does not govern.

2. If Dynamic Analysis is not mandatory by the client or the response spectra cannot bederived from data available, Equivalent Static Analysis can be done. However, ifEquivalent Static Analysis yields uneconomical results, Dynamic Analysis methods

may be adopted to achieve realistic results.3. Piping in this category are non-seismic critical. Systems shall be made rigid overallpreferably by having every 2
