Black steel A234 WPB Pipe fitting accessories Images
ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on.
In these standard Grade WPB is the most common material used for medium and high temperature pipelines. W means weldable, P means pressure, B is grade b, refer to the minimum yield strength.
ASTM A234 standard steel pipe fittings have been widely applied in pipeline systems, it includes carbon and alloy steel material.
It covers steel fittings of seamless and welded types. Steel Pipe fittings are applied in pressure pipelines and in pressure vessel fabrications.

In general, carbon steel pipe fittings and flanges are widely used for applications which do not require materials with higher resistance to corrosion such as stainless steel and alloy steel. Carbon Steel Fittings is primarily used across piping systems for its hardness, moderate to good tensile strength and inexpensiveness.
Butt weld fittings are manufacture by seamless or welded pipe. For pipe fittings manufacturers, the forming process of welded pipe and seamless pipe is basically same. Butt welded fittings can be divided into carbon steel butt welded fittings and stainless-steel butt-welded fittings
