1.0 PURPOSE

This design basis deals with the subject of Identification of Stress Critical pipelines and preparation of Critical line list. This procedure also defines the minimum requirements for performing stress analysis, design and location of spring, support and extent of system analysis 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 and pipe support analysis for new and modified piping systems for HPCL Mumbai Refinery for its DHT 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 Stress Critical 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 under review. 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 the Line 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 is exposed to direct sunlight, solar radiation temperature of 70

0 C is considered in establishing

the maximum temperature of piping. Even, for non-critical piping exposed to direct sunlight on pipe 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 and the design temperature, the design temperature should be taken as Flexibility temperature.If the 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 flare lines.’

Ambient Temperature shall be considered as 21 0

C. the assumed piping installation temperature. The displacement stress range from this installation temperature to the minimum recorded ambient temperature of 12

0C being less than the same from installation

temperature to the maximum operating temperature of hot piping in most cases the later governs 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 the categories defined in Attachment 10.1 and is intended to include the special requirements of Piping Stress Engineer. It is hence defined as any line for which a flexibility review is required or where pipe supporting is deemed to be critical and needs review by a Stress Engineer.Hence all lines following outside the categorization are deemed non critical which can be reviewed using nomographs manual calculation and/on visual analysis.

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

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 the natural frequency of the piping system. Such systems tend to store the energy and release it according to certain scientific laws. Such a system is dynamic in nature and the study of the response of such a system is referred to as “Dynamic Analysis”. Examples of such kind of systems are Relief Valve discharge lines, Safety valves / rupture discs, water hammer and surge in pipelines, two phase slug flow in pipelines, reciprocating pumps and compressor piping, submarine piping,pipelines subjected to earthquake of large magnitude etc.

4.3 SPECIAL PIPING

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

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

The critical line list shall be prepared from the project line list document by inserting following relevant fields such as

Stress category Critical (C) or Non-critical (NC), stress package no., stress analysis temperature, support critical nature of the line, dynamic loadings, steam out / purge temperature etc.

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 been included 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 a memorandum if a record is required.

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

6.0 PIPE STRESS ANALYSES AND SUPPORTING

6.1 Piping support Criteria and General Guidelines :

Piping system shall be properly supported taking in to account of the following points:

a. Sustained Loads:

• Weight of piping (Bare pipe, service fluid, valves, flanges etc.)

• Weight of insulation (if any)

• Weight of online equipment (if any)

• Weight of instruments (if any)

• Pressure relief load due to safety valve operation

• Wind / Seismic loads (as and when required)

• Dynamic loads due to pulsating flow/two phase with slug flow

• Pressure-Thrust loads in case of expansion joints.

b. Thermal Loads

Thermal loads due to operating / design / steam out / decoking or any other abnormal condition.

Pipe supporting shall be preferably follow the basic span as given in Piping Design Basis (Annexure D), except for flare line in offsite on trestles in which case the basic span shall be restricted to max.18m. For sizes not covered in Piping Design Basis, basic span shall be established based on project requirement. For piping on rack or sleeper, as a minimum, providing resting support on every grid of pipe rack / sleepers mandatory. Guides shall be provided on straight run of pipes at intervals as specified in piping design basis (Annexure C), unless specifically becomes non-viable due to flexibility problems.

Categorization for Seismic analysis

Definition: Plant Piping located in earthquake prone areas of the country will experience accelerations imparted through foundations, structures and various equipment. Criticai piping {toxic, flammable, high pressure, high temperature, emergency) which must remain leak;tight or operable (deliver, control or shutoff flow) during or following the event, have nozzle loads within vendor's set limits, have minimum sway to avoid impact or interference with adjacent equipment / pipes / structures need seismic analysis to determine 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 1893-2002 guidelines 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 than 90 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 and equipment are to be analysed accordingly. To get realistic results, it is essential that seismic analysis for piping be carried out using the Dynamic analysis method viz. Time History method or Modal Response Spectrum method. Piping connected to tail columns/vessels, chimneys and any slender structure should preferably be analysed using dynamic analysis. Long-run piping on tall slender structures (such as flare piping on trestles) should be analysed using composite analysis. For toxic/lethal piping systems, the seismic anchor movements also need to be imposed during the dynamic analysis. However for simplification's sake wherever dynamic analysis is not mandatory by the client or the response spectra cannot be derived from data available, seismic design can be done using the Equivalent Static (static coefficient) method.

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

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

» All critical piping systems aboveground with a weight (self+fluid+insuiation) greater than 410

kg/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 the above 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 or greater than 25m with a weight greater than 110 kg/m (corresponds to a 10" STD schedule water filled pipe).

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