ASTM A234 WPB pipe fittings carbon steel elbows used in pressure vessel fabrication and pressure pipelines
ASTM A234 WPB Elbow is one of the most used forms of pipe fittings. An elbow is a connector shaped like an elbow and allows for directional transformation in fluid flow.
WPB is the most commonly used carbon steel pipe fitting material for medium and high temperature application now, it can be made by steel pipe like ASTM A106 Gr.C or steel plate like ASTM A285 GR.C. This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction covered by the latest revision of ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97. Although these fittings normally adopt butt welding ends. A fitting used in any industry performs the function of changing either the rate of flow or the direction of the flow of media. In the instance of a Buttweld SA234 WPB Elbow, the change provided is with regards to the change in direction.
