Re: [MW:27296] SS Forged Bar machined to make Pipe for Nozzles Fabrication

Hi , 

In another way ,

Nowadays lots of technology come up for Weld overlay of 2 inch and lesser diameter from fronius and polysude .

We need to use the particular TIG torch if the vendor holds cladding machine.

Alternatively ... you can proceed with SS forged material as long as material is properly tested with IGC and material MTC is enclosed from the mill with all heat number details and need to do PMI on material before welded with vessel.

This is an additional information only.

Gents,

I have the following query. Appreciate if someone can guide on this:

Background: 

Cladded Vessel, Nozzle of Size 2", MOC: CS+SS Cladd/ Overlay, Code of Construction: Sex.VIII Div.1 : Vendor confirms that they cannot do weld overlay of 2" and less size. Alternative confirmed by vendor is to machine the Forged Bar to make 2" SS Pipe. Our Engineering has accepted the replacement of material from engineer point of view i.e from CS+SS Overlay to SS Matl.

Query:

Is it acceptable from code point of view to used forged item for manufacturing of Nozzle pipe.

Regards,

Ajay Kumar Dokku
