When specifying material for Pipeline fittings ( in oil ang natural gas service) we usually foung 2 acronyms: WPB and WPC for specifying material grade.
CASTI Guidebook to ASME, and some other general users call
WP = Welded Pipe ; B and C are grades.
As per ASME these are Wrought products (Grades B and C) (since the welded pipe is a misleading terminology , in fact it could have been weldable pipes)
WPB/WPC
