Dear Sirs,
I AM ALWAYS GETTING A POST DELIVERY FAILURE NOTE STATING THAT THE MESSAGE IS NOT DELIVERED. CAN ANYONE HELP ME OUT OF THIS.....
This is the very reason I am writing direct mail, sincere apology for same. Query below -
The PWHT Temp range is different in ASME B31.3(Table 331.1.1) and ASME Sec VIII Div 1(Table UCS 56), but both are from ASME. The welding and welder qualification are as per ASME Sec IX, for both B31.3 and Sec VIII, Div 1.
Why ASME Committee put such a different requirement although both are published from ASME and material grouping is also the same, means the metallurgical properties should be same, i assume.
What should be the criteria of PWHT for PQR run on a Pressure Vessel? If I have qualified a PQR using ASME B31.3 taking account of B 31.3 PWHT Criteria, is it acceptable to have the same PQR on Pressure Vessel (Designed as per ASME Sec VIII, Div 1).
Looking forward for a technical clarification.
Thanks & Regards
Vino-Doha
