Dear Experts,

We have a Weld joint between Pipe to Hub as per sketch.

Run Pipe Thickness : 25.4 + 3 mm Cladding

Hub Thickness         : 31.8 + 3 mm Cladding    

Job Type : Weld joint in Piping

Code  : ASME B31.8-2020 Edn

Question 1 : For PWHT whether we need to consider Run pipe Thickness or Hub Thickness?.

Question 2 : If Run Pipe is considered for PWHT whether it includes Cladding Thk also?

Question 2 : If Hub is considered for PWHT whether it includes Cladding Thk also ?

Need your Views on this.

Regards,

Manikandan
