PWHT Requirement for clad plate vessel

[israr]

Dear Friend,
i have a vessel of 70 mm thick with internal lining of ss 316L plate.

I am not getting how to carryout heat treatment after welding of
internal lining,
I have suggested to use clad plate but there may chances to open clad
during heat treatment.
please help.

Regards
Israr Ahmed

can you tell me the material of that 70 mm thick vessel?

Apply calcium carbonate on clad surface and do PWHT. It will protect Clad.

Hi Israr,

 

Regarding the heat treatment for lined vessel you can refer ASME SEC. VIII Div. 1 section UCL 34 and for examination of stainless lining refer UCL 36.
