Butt Weld Pipe Fittings

We take immense pleasure to introduce ourselves as a manufacturer of pipe fittings of Stainless Steel, Carbon steel, Alloy Steel and High Nickel Alloys. The offered range of butt welded pipe fittings is known for its corrosion resistance, durability and high tensile strength. Butt weld is to connect pipes and fittings ends by butt welding process. Also known by welded pipe fittings. It has ends in beveled or plain, dimensions normally from 3/4'' to 24''. Manufactured according to ASME B16.9. Clients can avail these products as per their dimensional specifications. The products offered by us are available at market leading prices for our customers

Pipe fittings are available as Elbow, Long Radius Elbow, Short Radius Elbow, 90 Deg Elbow, 45 Deg Elbow, 180 Deg Elbows, 1D Elbow, 3D Elbow, 5D Elbow, Tee, Equal Tee, Unequal/Reducing Tee, Reducer, Concentric and Eccentric Reducer, End Cap / Pipe Cap, Stubend, Long & Short Stubend, Swage Nipple, Barrel Nipple, Reducing Nipple, Bend, Long Radius Bends, Piggable Bend, Equal & Unequal Cross and out lets (olets). These fittings are the most common type of welded pipe fitting and are specified by nominal pipe size and pipe schedule. Buttweld fittings use seamless or welded pipe as the starting material and are formed (through multiple processes) to get the shape of elbows, tees and reducers etc.
