PQR according to ASME Code sec. IX
PQR according to ASME Code sec. IX
(OP)
Good morning and excuse me for my English
the question is:
I need to qualify (in accordance with ASME code sec IX) the welding procedure of a pipe A333 Gr6 with a pipe A335 P11 (Cr-Mo-Si).
The job temperature is -15°C. I shall do Impact test in Weld Metal - Base Metal - HZA, to -20°C.
It is necessary to do Impact test on Base metal on pipe A335 P11? The pipe material certificate is tested at +20°C.
Many thanks
Regards

RE: PQR according to ASME Code sec. IX
What Code section are you fabricating to? Based on the information supplied, impact testing would be required for the P11 pipe at -15C.

the Code is ASME and PED 97/23 CE.

many thanks for your reply.
The design code is ASME sec. VIII and I shall do impact test on pipe P11 at -20C (so I increase the range) in HAZ and Weld metal.
Can I omit impact test on base metal P11? Or I have to test it at different temperature (for example +20C)?
Thanks again
