Grade WPB is the most common material for medium and high temperature pipelines in these standards. W stands for “weldable,” P for “pressure,” B for “grade b,” and Y for “yield strength.”
ASTM A234 is the Standard Specification for steel pipe fittings. It includes materials made of carbon steel and alloy steel for use at both moderate and high temperatures. It has to do with both seamless and welded steel fittings. A234 pipe fittings are used in pipelines that carry high pressure and in the making of pressure vessels. These A234 pipe fitting are made from killed steel, forgings, bars, plates, seamless or HFW (fusion-welded) pipe products, and filler metal.
ASTM A234 covers seamless and welded carbon steel and alloy steel fittings covered by the latest revisions of ASTM B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97.
SA 234 steel pipe fittings are used in pressure piping and the making of pressure vessels for services at both moderate and high temperatures. In this standard, the materials for A234 pipe fittings are killed steel, forgings, bars, plates, and seamless or fusion-welded tubular products with filler metal.
