[MW:4825] ASME B 31.1 welded pipe in boiler external piping

[Nivendkar Vinayak (Mumbai - Piping)]

Dear all,

 

As per ASME B 31.1 Anex –A Table A-1 note 1 , it seems that we could not used welded pipe A 671 , A672 for pressure retaining parts of external boiler piping .

But for the same time Plate material A515,A516 is allowed.

 

Now my query “are welded pipes are not allowed for boiler external piping   as per ASME B 31.1.

 

Kindly reply.

 

Regards,

Vinayak Nivendkar

Hello Vinayak,

 

Yes you are correct ASME 31.1 only allows SMLS pipe for boiler external piping, mentioned plate materials are for manufacturing of other items.

 

Kind regards

Rahul
