Technical Data Handbook for Butt Weld Pipe Fitting and Forged Steel Fittings
What is Butt Weld Fittings
Butt weld is to connect pipes or fittings ends by welding. It’s a weldable steel pipe fitting that would allow to branch off, allow for change of direction of flow, attach auxiliary equipment, or reduce the size of the pipe. In the case of forged steel butt weld fittings, you would find them to be manufactured according to ANSI/ASME B16.9.
Buttweld fittings are available in multiple shapes (elbows, tees, reducers, crosses, caps, stub ends), material grades (carbon, high-yield carbon, low-alloy, stainless, duplex, and nickel alloys), and dimensions (2 to 24 inches in seamless execution and welded for larger pipe sizes).
The key specifications for buttweld fittings are the ASME B16.9 (carbon and alloy fittings) and the MSS SP 43 (that integrates ASME B16.9 for stainless steel, duplex, and nickel alloy BW fittings).
Butt welding fittings have the following benefits
allow strong, and leak-proof, piping connections.
minimize pressure drops and the turbulence inside the pipeline.
have a long service life.
are rather cheap to purchase and deploy.
