MANUFACTURER/EXPORTER IN INDIA | ASME/ANSI B16.9, ANSI B16.28, MSS-SP-43

CARBON, ALLOY, STAINLESS STEEL BENDS – 3D, 4D, 5D, 6D, 8D, 10D

Sunmax Steel & Engg. Co. is a leading manufacturer, exporter and supplier of stainless steel bends, carbon steel bends, and alloy steel bends in a complete range of radius and diameters. Steel pipe bends can be manufactured from a wide range of pipe materials – including low and high yield carbon steels, alloy steels, stainless steels, Cr-Ni alloys and titanium. We specialise in the manufacture of large and small size stainless steel bends and piggable bends in grades Duplex, 310S, 304L, 316L, 317L, 347, 321, 904L.

Generally stainless steel bends and carbon steel bends can be manufactured from seamless or welded pipes, but the choice is made taking into consideration the technical challenges involved.

Increasing number of customers in the petrochemical industry are choosing stainless steel bends, carbon steel bends and nickel alloy bends as a preferred option for modern piping and tubing systems, as good quality pipe bends significantly reduce the need for welding and use of pipe fittings. Use of stainless steel bends, carbon steel bends and alloy steel bends in piping systems also improves the flow of fluids in the piping system.

Our pipe bends find applications across various industry verticals such as petroleum, power generation, natural gas, chemicals, ship building, and other industries.
