Although no restriction in code preferable methoud could custom build modular furnace (with panel construction) at site

It is straight forward method for cir seams, however for long seams you have to work a methodology for placing coils locally using WRC 452 guidelines, probably  supplimented with an FEA to check thermal stresses

Subject: PWHT Segment Wise for 9 Meter Dia Vessel

 

Dear All,

 

We are fabricating a Vessel of Diameter 9 Meter at Site, requires PWHT: Material Grade SA 516 Gr. 70.

 

 For Circumferential Joint PWHT can it be performed Segment Wise as diameter is more??

 

Pl. Confirm as per ASME Sec VIII Div 1 can it be done in Segment Wise.
