Reliable Steel Distributors 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.
Weld neck pipe flanges are connected to the pipe by welding the
pipe to the neck of the pipe flange, which helps to pass on the stress from the weld neck to
the pipe itself. This also reduces high stress concentration at the base of the hub of the
weld neck pipe flanges. Weld neck pipe flanges are generally used in high pressure
applications, where hot or cold temperatures exist. The inside diameter of a weld neck pipe
flange is machined to match the inside diameter of the pipe.
We offer weld neck pipe
flanges manufactured at our facility to companies in various industries including
shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment
plants, paper mills, pharmaceutical plants and turnkey projects among others.
