Introduction
Piping loops had been stress analyzed according to supports marked in isometrics provided by HWB and twenty-six loops did not qualify the design adequacy re-evaluation. For these loops, retrofitting has been proposed. The piping stress analysis has been carried out again for these loops incorporating the proposed retrofitting. This report presents the retrofitting arrangements, the results and conclusions of the piping stress analysis after incorporating these changes in these twenty-six piping loops. The isometrics marked with retrofit modifications are in a separate CD. The relevant EIL piping support standards are included in the Appendix and may be referred for the support details.
The following points may be noted with regard to retrofitting
1. The analysis has been carried out at design temperature, when normally wind and seismic should be analyzed at operating conditions. Further the sustained and thermal load cases should also be analysed.
2. The plant was designed as per B31.3 but the re-evaluation was requested to be carried out as per ASME Section III, ND Class. Stress in piping has been checked as per ASME Section-III ND Class. However HWB may ensure flexibility checking as per ANSI B 31.3, before retrofitting as it was the original code for piping design in HWP (Manuguru).
3. The status of guides and other supporting (especially those on pipe racks were not known, as isometrics for the same was not available, and some assumptions have been made). The same needs to be first confirmed at site before any modification can be carried out.
It should be noted that modifications in a plant running successfully for three decades should be carried out with extreme care. This is applicable more so for piping because guiding, restraining or strengthening a particular section may result in transfer of loads to another section of piping or equipment nozzles not only for wind and seismic cases but thermal case as well.

2.3 CONCLUSION The piping stress analysis has been carried out for the piping from nozzles ‘N1 & N2’ of Exchangers (12-E-109/209 & 12-E-110/210) to nozzle ‘F2’ of 1st Stage Cold Tower (12-C106/206) after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases are marginally exceeding the allowable stresses. Hence the system may be deemed to qualify the design adequacy re-evaluation after retrofitting. Template No. 5-0000-0001-T2 Rev. 1

3.3 CONCLUSION The piping stress analysis has been carried out for the piping from the nozzle ‘N1’ of Exchangers (12-E-102/202 & 12-E-104/204) TO nozzle ‘F2’ of 12-V-102/202 after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases are within the allowable stresses. Hence the system may be deemed to qualify the design adequacy reevaluation after retrofitting.

4.3 CONCLUSION The piping stress analysis has been carried out for 2CT Transfer pumps’ discharge to 3CT (12C-111/211) feed inlet & 2HT (12-C-110/210) feed inlet after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases are marginally exceeding the allowables. Hence the system may be deemed to quality the design adequacy re-evaluation after retrofitting.
It is to be noted that the stresses in the system are marginally exceeding the allowables only at the tee connection (Caesar Node No. 255), where the thickness of branch connection is 3.08 mm. If this tee connection is replaced with one having the thickness of the branch 4.0 mm or more, the stresses reduce to less than allowables.

6.3 CONCLUSION
The piping stress analysis has been carried out for piping from 2nd Stage Hot Tower Discharge Pump 12-P-117/217 to Dump Tank (12-V-104/204) & 1st Stage Hot Tower (12-C-107/207) after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases marginally exceed the allowable stresses. Hence the system may be deemed to qualify the design adequacy re-evaluation after retrofitting.

7.3 CONCLUSION
The piping stress analysis has been carried out for 2nd Stage Liquid re-dump line to 2HT (12-C108) after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases are marginally exceeding the allowables. Hence the system may be deemed to quality the design adequacy re-evaluation after retrofitting.
It is to be noted that the stresses in the system are marginally exceeding the allowables only at the tee connection (Caesar Node No. 255), where the thickness of branch connection is 3.08 mm. If this tee connection is replaced with one having the thickness of the branch 4.0 mm or more, the stresses reduce to less than allowables.

8.3 CONCLUSION
The piping stress analysis has been carried out for the piping from Pumps (12-P-124/224A/S) discharge to nozzle ‘N2’ of Exchanger(12-E-123/223) and nozzle ‘N1’ of Exchanger (12-E123/223) to nozzle ‘R’ of 3rd Stage Cold Tower (12-C-111/211) after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases are within the allowable stresses. Hence the system may be deemed to qualify the design adequacy reevaluation after retrofitting.

10.3 CONCLUSION The piping stress analysis has been carried out for the piping Pumps (12-P-122/222A/S) discharge to nozzle ‘N1 & N2’ of exchanger 12-E-118/218A/B , nozzle ‘N7’ of exchanger 12-E117A and nozzle ‘F1’ of 3rd Stage Hot
Tower (12-C-110/210) after proposed retrofitting
modifications.
The results indicate that the stresses for the individual wind and seismic load cases are marginally exceeding the allowables. Hence the system may be deemed to quality the design adequacy re-evaluation after retrofitting.

11.3 CONCLUSION The piping stress analysis has been carried out for the piping from nozzle ‘N1’ of Exchanger (12-E-120/220) to nozzle ‘F1’ of 3rd Stage Cold Tower (12-C-111/211) after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases are within the allowable stresses. Hence the system may be deemed to qualify the design adequacy reevaluation after retrofitting.

12.3 CONCLUSION The piping stress analysis has been carried out for piping loop from 3HT transfer pumps’(12-P120) discharge to 3CT (12-C-111) after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases marginally exceed the allowable stresses. Hence the system may be deemed to qualify the design adequacy re-evaluation after retrofitting.

The piping stress analysis has been carried out for piping loop from 3HT (12-C-110/210) liquid dump to dump tank 12-V-106 after proposed retrofitting modifications. The results indicate that the stresses for the individual wind and seismic load cases marginally exceed the allowable stresses. Hence the system may be deemed to qualify the design adequacy re-evaluation after retrofitting.

16.3 CONCLUSION
The piping stress analysis has been carried out from pump ( 12-P-123) discharge to product stripper feed after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases are within the allowable stresses. Hence the system may be deemed to qualify the design adequacy reevaluation after retrofitting.

17.3 CONCLUSION
The piping stress analysis has been carried out for the piping from product stripper O/L nozzle ‘N4’ to nozzle ‘N8’ of exchanger (12-E-125/225) & nozzle ‘N3’ of Exchanger (12-E-124/224) after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases marginally exceed the allowable stresses. Hence the system may be deemed to qualify the design adequacy re-evaluation after retrofitting.

18.3 CONCLUSION The piping stress analysis has been carried out for the piping from the nozzle ‘N1” of Product Stripper to nozzle ‘N6’ of Exchanger (12-E-126/226) & liquid back to nozzle ‘N2’ of Product Stripper after proposed retrofitting modifications.
The results indicate that the stresses for the individual wind and seismic load cases marginally exceed the allowable stresses. Hence the system may be deemed to qualify the design adequacy re-evaluation after retrofitting.
