Mmmmmmm sorry I should have said that the material is SA-516-70, this is ferritic steel welded with E7018, so I believe UHA-33b and UHA-33a do not apply?

Dear Friends,
We need to check all requirements in line with code specific to the item . Certain codes do specify NDT after PWHT . Certain client specifications specify the NDT requirements after PWHT . so do not conclude requirements in general.You may refer this in BS 5500 for pressure vessels or B31.3 for piping Regards,

I don't believe there is any requirements, but
on P5-B materials, it is a common practice as cracks have been known
to form after 24 hours on these materials. I have heard of some materials
on "Hold" pending another RT after the initial test after 7 Days. I have just completed PWHT on ASME 1 piping and
there is no requirement on P1 material for additional RT after cool
down.

Dear friends
We just finished PWHT in an LPG sphere acording to ASME VIII
section I, and I can´t find in the code the part that obligues to Xray
after this treatment, any one has experience with this? where does
ASME VIII say it has to be done?
Thank you
Luis Albanés
