welder qualification with out P-no as per sec IX

[EngrRodri]

Guys

Need your help, I will be conducting WQT by next week with our WPS that is qualified for API X60 PIPE and A707 CL3 L5 FLANGE. API X60 IS P1 GR2 and A707 CL3 L5 FLANGE does not have Pno assignment as per ASME SEC 1X

question? can we have substitution in WQT. instead of A707 CL3 L5 FLANGE we will used API X60 PIPE because it has the same min 75 KSI tensile strength. Also cost of material for A707 flange is expensive..


Thank you
