ASTM A 694 F65 pup piece

[amju005]

Dear All,
I have a doubt please support me to clear it;
Our pipeline material is API 5L X65 and has a Valve of material ASTM A350 LF2, accordingly the pup piece designed is API 5L X65, but the vendor propose for ASTM A 694 F65 pup piece. Is it possible to manufacture forged (ASTM A 694 F65) or wrought (MSS SP 75 WPHY 65) line pipes?
As per my understanding the welding has no issues, as the WPS for the same will be developed for the other fittings (eg. Flanges,anchor flanges and IJ)

It's rather odd, but not a big issue.

Can you sketch your system add to why you need a pup piece, Is this to go from your weld end valve to your pipe?

What is the size of the pup piece?, what are the wall thickness differences? You may not need a pup piece.
