ASTM A234 is the Standard Specification for steel pipe fittings made of carbon and alloy steel for moderate and high-temperature applications. W stands for weldable, P stands for pressure, and B stands for grade b, which denotes the minimum yield strength. It applies to both seamless and welded steel fittings. These Carbon Steel A234 WPB Buttweld Fittings are constructed from killed steel, forgings, bars, and plates, as well as seamless or HFW (fusion welded) pipe products with filler metal.

Carbon Steel A234 WPB Buttweld Fittings are helpful in pressure pipeline fabrication for moderate and high-temperature services. ASTM A234 covers seamless and welded wrought carbon steel and alloy steel fittings covered by the most recent versions of ASTM B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97, among others.
Alpha Overseas is a notable manufacturer, supplier, and exporter of Carbon Steel A234 WPB Buttweld Fittings in Mumbai, India. The A234 WPB butt-weld pipe fittings are available in various types, including elbows, tees, bends, reducer crosses, end caps, lap joint stubs, nipples, and couplings.
A thorough dimensional evaluation and visual inspection are required. PMI heat analysis and tensile testing must be done to evaluate its chemical composition and mechanical qualities. Other tests, such as Liquid Penetrant Inspection, Magnetic Particle Examination, Eddy-Current Test, and Ultrasonic Test, may be done if needed.
