Re: [MW:27298] SS Forged Bar machined to make Pipe for Nozzles Fabrication

Dear Ajay 

Forging can be machined to required size of nozzle. Ideally manufacturers facility does permit nozzle weld overlay, they prefer to go ahead with SS pipe.

Pl check project engineering specs

Is it allowed to have nozzle material to weld on classes shell?

If allowed, better to use heavy schedule pipe.

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
