Subject: [MW:25809] Temporary piping used in hydrotest - ASME B31.1

Dear Experts,

  Could you advise us: For piping system hydrotests power plant project, we ave to prepare and use some temporary piping. The issue is :

- Is it Manadatory to perform NDE in related welds  and also PWhT

NO FOR EITHER, 

BUT FOR PWHT - ANY WELDING INDUCED STRESSES IN EXCESS OF YS MAY BE UNDESIRABLE.

PERFORMING NDE ON ALL INCLUDING TEMPORARY MEMBERS WILL BE IN YOUR BEST INTEREST. IF A JOINT LEAKS BECAUSE OF ANY WELD DEFECTS, YOU WILL FACE EXTRA COST, ADDED TIME, RE-SCHEDULING, ETC  DUE TO  RE-HYDRO.

- For Flange fabrication, how to use plate thickness, any code or standard reference !

PLEASE SEE ATTACHED

Please advise according your experience and with ASME reference .

Thank you.
