PWHT For H2S Socket Weld

[Mostafa Kamel Hussein]

Dear Sirs

Kindly be informed our specification mandates PWHT on H2S piping classes regardless its material type except on socket weld  up to 8mm (wall thickness). my question is what is meant by wall thickness? is it base metal thickness of throat thickness? as you know it'll be differed because thickness of fitting is higher than piping thickness in same schedule.

Kindly clarify the meaning and support us with strong evidence if found.

Regards,

M.Kamel

I would strongly recommend NOT USE socket welds in H2S service. The risk of crevice corrosion is to high
