API 5L grade B PSL2 in US?

[smundra0324]

Hello I am trying to order replacement pipe with flanges to match current pipe system. The diameter is 28" and i am having diffulcutly in flange specification. Also I require PSL2 and am having a problem locating a vendor in the US. Can I use a PSL1 or other suggestions or purchase from outside US?

Use pipe spec - API 5L Gr. B. PSL-2, DSAW Flange spec - ASTM A105N, Class
150 RF. WN B16.47-A (Bore to match pipe)

We commonly specify flanges to match the schedule of the piping it connects to (usually designated as "SCH 80" or "STD" for our pipeline work). This will match the flange bore with pipe bore. After providing the forged material spec (ASTM A105), we also specify ASME B16.5 (as opposed to B16.47). I'm not familiar with B16.47. May I ask - are there any reasons you would use B16.47 over B16.5?
