Buttweld fittings ASME B16.9 (carbon, alloy), ASME B16.9/MSS-SP 43 (stainless and nickel alloys): definitions, materials, sizes and types (elbow, cap, reducer, cross, tee)

Buttweld Fittings in Piping (ASME B16.9)

Buttweld fittings are used to change the pathway of a pipeline (elbows), reduce/increase its bore size (reducers), branch (tees, cross) or blind it (butt weld cap). BW fittings are used for pipes above 2 inches in diameter, whereas socket weld and threaded fittings are used for smaller size pipes.

Buttweld Fittings Dimensions (Elbow, Reducer, Tee)

The ASME/ANSI B16.9 specification covers the dimensions and the tolerances of carbon and alloy butt weld fittings. The MSS-SP 43 specification integrates ASME B16.9 to cover stainless steel and nickel alloy pipe fittings. In this article, we show the dimensions and weights of buttweld elbows, tees, and reducers.
