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.
