Dear Sir,
Situation:
Welding of pipe branch connection with RF pad.
Header size: 20mm; Thickness of RF Pad: 20mm
Branch pipe thickness: 10.97mm
Whether PWHT is required for the branch connection?
As per ASME B 31.3, Clause 331.1.3 (a), the PWHT control thickness is the lesser of the below two conditions,
(1) the thickness of the weld [ As per clause 331.1.3 (b) (5) the control thickness of branch can be calculated.]
(2) the thickness of the materials being joined at the weld or the thickness of the pressure-containing material if the weld is attaching a nonpressure containing material to a pressure-containing material.
Here can i consider (2) as 20mm as that is the thickness of the material being used in this situation and consider the same as the control thickness for PWHT?
