SA234 WPB explained
SA234 is the standard specification for wrought carbon steel butt weld fittings for moderate and high-temperature service, and Grade WPB is its most common grade. It is made to match SA106 Grade B pipe. Fittings are dimensioned to ASME B16.9, which fixes centre-to-end dimensions so that fittings from different sources are interchangeable.
Always match the fitting schedule to the pipe it will be welded to, so the bores and wall thicknesses line up at the weld preparation.
