mild steel flange with carbon steel flange
mild steel flange with carbon steel flange
(OP)
Hi
The flexible hose we have ordered came with flanged connection as per our requirement. but I found the flange material is mild steel ASA 300 while we asked for carbon steel flange material A 105 class 300
what i know is mild steel has low carbon content and is more malleable and it is not suitable to join 2 difference flange material. is this correct?
Also, ASA is the old name of ANSI, but is ASA 300 welding nick flange match ASME B16.5 class 300 (pressure rating)?
I am confuse otherwise i have to back this material to the supplier soon.
regards

RE: mild steel flange with carbon steel flange
Find the catalog or cut sheet from which you ordered, and find the related sheet that explains the product markings.
Or ask the supplier's sales engineer to explain how, exactly, what you got is what you asked for.

A105 is about as mild as you can get.

but I need clarification regarding join of 2 difference material flange, Is it accepted by ASME B31.3?

Check with your welding engineer for low to high alloy welds. You'll need a welding procedure anyway.
If the flange faces match, yes.
