ASME-B.31.3 2014 edition, Table 331.1 Postweld Heat Treatment
(OP)
Hello,
In ASME B31.3 edidtion Table 331.1.1 Postweld Heat Treament for P.No.1, Group Nos. 1-3: Holding Temperature Range, 595 to 650 Deg. C; Minimum Holding Time at Temperature for Control Thickness up to 50mm is 1h/25mm.... My interpretation to this is that All P.No. 1, Group Nos. 1-3 are subject to PWHT regardless of the pipe wall thickness, Can you please clarify?
Thank you and regards,
Andrewski
