Stancor offers a range of Electric Fusion Welded Pipe in different sizes and standards. It is a pipe, which is a tubular section or hollow cylinder, and generally but not essentially of circular cross-section. Electric Fusion Welded (“EFW“) pipe is formed by rolling plate and welding the seam. Pipe is generally manufactured to one of several international and national industrial standards. Many industrial and government standards exist for the production of pipe and tubing. Meanwhile, Pipe assemblies are more or less for all the time constructed by means of the usage of fittings such as elbows, tees, and so on.

Stancor EFW Pipe Division consists of a JCO Forming Press, Helical / Spiral Mill, Inside and Outside Welding System, Heat Treatment Furnace and Testing Facilities with an annual installed capacity of 3,000 MT.

Welding process employed is GTAW for root-pass and SAW/TIG for final pass with suitable filler wires as prescribed by AWS specifications and ASME Boiler and Pressure Vessel Code, section-IX. These facilities are capable of manufacturing Austenitic and various Duplex grade
