Re: [MW:11719] Approval thickness range in accordance with ASME IX and B31.3

if impact testing is required for the component you need to follow B31.3 requirement also , but you can qualify it as PTC, need not be specified on WPS, however if you want to avoid PTC, then you can specify the limits as 0.5T - T+6mm on WPS)

Dear Experts

 

T qualified is specified in ASME Sec. IX QW-451.2 and QW403.6(Max. 2T) and ASME B31.3 Table 323.3.1(0.5T ~ T+6mm).

 

For piping works for offshore, Shall these two requirements be kept ?

 

Best regards,
