What are Pipe Bends? Material Grades & Manufacturing Standards

Sandco Metal industries is renowned manufacturer, supplier and exporter of Butt Weld Pipe Bends & fittings from past 25 years which includes stainless steel bends, carbon steel bends, alloy steel pipe bends. Butt welding is a technique which is mainly used to connect parts which don’t overlap and are nearly parallel. Butt welding is economical and reliable way for joining pipes together done by gradually heating up the two weld ends with a weld plate under a specific pressure. 

This process is very suitable for prefabrication and producing special pipe fittings products. Butt weld fittings connect pipes by welding them together to provide them greater strength and compatibility to allow change in direction or pipe diameter, branching or ending to cover long and short distances.

We provide butt weld pipe fittings in various available grades and dimensions at affordable cost with no quality compromise. Our products are available in all major grades of stainless steel (304/304L fittings, 316/316L/316Ti fittings, Super Duplex fittings, Duplex fittings, 904L fittings and other steels), carbon steel and alloy steel and are manufactured in accordance to ASME, ISO, EN and DIN standards. 

We also provide our customers with personalized Butt Weld Fittings like cutting, polishing and threaded products & electro polished stainless steel fittings with complete excellence.

Our motto is customer satisfaction by providing them durable, long lasting and premium quality butt weld pipe fittings under ISO-9001:2008 certifications.

We are manufacturing  large and small size stainless steel bends and piggable bends in grades Duplex, 310S, 304L, 316L, 317L, 347, 321, 904L at acceptable cost. Stainless steel pipe bends, copper steel bends, alloy steel bends are used in various industries like oil and gas, petrochemical , power generation, ship building etc.
