Hello friends, greetings. I need help.
I have a weld metal with base P No. 4, High pressure pipe with wall thickness of 8.0 mm, in accordance with paragraph K331.1.3 (b) (1) of the code ASME B31.3, which temperature should be used?
Thank you

This is for B31.3, not B31.1

(a) Heat treatment is required for all thicknesses of P-In. 4 and 5 materials.
So what temperature should I use, and this value should be set By Design engineering

PWHT is 704 to 746 deg C.
