Process Piping LTCS PQR with Impact test

[SWI]

Dear Group,

While qualifying a PQR as per ASME SEC IX for Process piping ASME B31.3, in WPS the thickness limit will be as per ASME SEC IX QW403.6  or we need to refer QW403.6 & ASME B31.3 Table T323.3.1 A-5.

Regards,

TR

if impact is there, refer 31.3

THANKS & BEST REGARDS,

The order of precedence is always the design/fabrication Code then Section IX.

 

Hope this helps.
