2.
Make sure the pipe is installed end to end before you even start to work on the problem per aaministrative guideline No.
8 Fore large bore piping, this limitation does not apply.
3.
Before you begin to analyse your line, check the composite piping drawing for any adjacent lines in our scope that can be gang supported with your line. Gang supports must be used wherever possible. When any support on your line is gang supported, it shall be stated as such on the cover-sheets of all corresponding analysis packages giving the corresponding support Numbers and Isometric Numbers. All gang support feasibility.shall be consulted with hanger design group.
4.
Make sure the supports can be physically installed in the field at locations specified by you on your support location isometric.
If support location is questionable, consult with hanger design group before proceeding further.

PIPE STRESS ANALYSIS r
1.0 WORK SCOPE The Scope includes all Class 2 & 3, 2" diameter pipe and certain 21/2", 3" and 4 Class 2 and 3
- lines, fall within the parameters of the criteria. Tho detaileh letter GTN-43993 (" Safety Class Lines Qualifying for non scope can be determined from Attachment 1 of GilLbs & Hilj 1
Computer Analysis", Rev.1,1/5/80), PITS (Piping Informa-tion Tracking System), the Gibbs & Hill line No. - Stress Problem No. correlation, and any correspondence adding or de-leting specific line numbers. All work is performed in accor-dance with the applicable Comanche Peak engineering procedures and engineering instructions established for the Mechanical Engineering Group and standardized group engineering and draft-ing manuals.
2.0 GENERAL 2.1 Simplified Piping Analysis All Class 2 and 3 lines identified in the above scope require analysis to detennine support locations and loads.
2.2 The document used will be Gibbs & Hill Simplified Analysis 4--%
Criteria, dated January 1980 Determination of which criteria to use is provided in the attachment to GTN-43993. Forms DHE-5 and DHE-13 thru DHE-20 have been developed to assist the Stress AnalysiTEngineer iTperforming his analysis.
3.0 PROCEDURE 3.1 The pipe analysis lead engineer will make assignments based on the design schedule commitments specified by " HITS".
3.2 Obtain a copy of the current revision of the "BRP" iso, and any outstanding CMC's.
3.3 Pull the iso folder for that iso from the file and insert an "out" card with date, iso number and initials.
If there is no folder, have a clerk create one with your initials on the out card. This will ensure that you will receive all CMC's written against the BRP after work has been started on it.
3.4 Check the reference file for data on any valves, instruments or connecting equipment shown on the iso.
If none is available, obtain information from DCC.
u 2 of 4 Rev. 1 3.5 Refer to the simplified analysis scope line list to determine design parameters and the suggested criteria to use in the analysis.
3.6 Refer to the appropriate section of 2323-MS 46A for identifi-cation of pipe properties from the pipe specification indicatej in the line number.

7 Code Class 3.7 Refer to the piping composite drawing referenced on the BRP iso to determine piping and equipment located in the vicinity of the line to be analyzed.
3.8 Check the area in the field, and get a feeling for good areas to support the piping and areas that will be difficult or impossible to support.
3.9 Based on all the information obtained at this point, proceed with the analysis and determine necessary interfaces, support locations, loads, support types (rigid, snubber, spring).
3.10 Unless specific data is given, seismic displacement at terminating equipment are assumed negligible. Thermal displacements at term-inating equipment must be calculated by the Stress Analysis Engi-neer unless otherwise provided.
3.11 Seismic and thermal displacements at connecting rigorously-analyzed pipe are to be checked. See the analysis section lead engineer for this information.
3.12 Nozzle loads on equipment will be calculated. An effort will be
.made to place supports such that these reaction loads are as low as possible.
In the event that the calculated loads exceed the i
vendor allowables, document this problem on the analysis cover sheet OHE 14 and in the system punch list. Discrepancies will be resolved with the vendor at a later date.
3 of 4 Rev. 1 3.13 Small lines connecting to rigorously analyzed pipe may have been partially included as over lap in the analysis.
The following rules govern inclusion in the analysis:

3.14 All assumptions made in the analysis will be documented.
3.15 All open items will be documented in the system punch list.
It will be the responsibility of the analysis section Lead Engineer to see that these punch list items are periodically reviewed and cleared at the earliest possible date. All open items are to be resolved and incorporated in the design by the hot-functional test date.
3.16 The Stress Analysis Engineer will provide the lead Stress Analysis Engineer with the signed-off calculations and a marked-up iso showing locations, loads and specific informa-tion.
3.17 Checking / Design Review for the Pipe Stress Analysis Package.
3.17.1 The Pipe Stress Analysis Engineer will initial and date each calculation sheet DHE-4 and all applicable foms in the " CALC" Block, then make a check copy of the corapleted analysis pack-age, and give the package to the Lead Pipe Stress Analysis i
