Re: [MW:33177] RE: PWHT Segment Wise for 9 Meter Dia Vessel

What diameter can your furnace accommodate?. 9 Meter seems to be Big.

There are some options if your Furnace cannot accommodate.

1.  Try for a Temporary furnace with proper insulation and Heating arrangements. Hope there are some subcontractors available.

2. Try for LOCAL PWHT of the seams.

3. Below option may be useful if you have difficulty accommodating the Length in one Heat.

Thanks & Regards

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.
