Pipe, Flanges, Forgings and Fittings for Sour Service (wet H2S)

[jstrom9]

I was asked by a senior ME at my firm about some additional designations for piping materials. He asked me to look into it to see what these designations meant and if the suppliers we use are able to provide this specific material. What code or standard are these things covered by? The additional designations are in red below.

SA-105N, 20 (subgroup JB/T 4726) - forgings

SA-106 Grade B, 20G (subgroup GB 5310) - seamless pipe

He also asked me to find out if SA 234 WPB welded pipe and fittings can be bought in a normalized condition.

Thank you for the assistance.

Ask for ASTM A234 N

Independent events are seldomly independent.
