Buttweld Fittings ASME B16.9

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.

BW Fittings Materials: ASTM A234, A403, A815, B366

A complete overview of ASTM materials for buttweld fittings: ASTM A234 (carbon and low-alloy steel), ASTM A403 (stainless steel), ASTM A815 (duplex and super duplex), and ASTM B366 (nickel alloys). The article reviews the chemical and mechanical properties of these pipe fittings specifications and their common uses. BUTTWELD FITTINGS MATERIALS Carbon steel buttweld fittings are common… read more »

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. BUTTWELD FITTINGS DIMENSIONS ASME B16.9 45/90 Deg…. read more »

Stub End Benefits (ASA, MSS)

What is a stub end and why should it be used? Stub ends are buttweld fittings that can be used (in combination with a lap joint flange) alternatively to welding neck flanges to make flanged connections. The use of stub ends has two advantages: it can reduce the total cost of flanged joints for piping… read more »
