What is Buttweld Fitting? A buttweld fitting is a weldable pipe fitting that allows changing the pathway of flow, to reduce or increase the pipe bore size or attach auxiliary equipment. Forged Steel buttweld fittings are manufactured in accordance with ANSI / ASME B16.9. Buttweld fittings are available in different grades, dimensions, and multiple shapes i.e. they are available in (elbows, tees, caps, reduces and outlets). These pipe fittings are the most common type of welded pipe fitting and are specified by nominal pipe size and pipe schedule . Cast Iron, Aluminum, Glass, Rubber, Alloy, Stainless Steel, Carbon steel are some of the most common materials used to produce a buttweld fitting, but to develop the shape of elbows, tees, reducers buttweld fittings use the seamless or welded pipe as the starting material which is then formed through multiple processes. Some of the benefits of Buttweld fittings are; The Welded connection helps to ...
