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?
