The Electric Welded pipes in HFW category are increasingly accepted for High Integrity applications in the Oil & Gas sector: For its improved Dimensional Control all along that helps coating/field joint efficiency.Precise control of Mechanical Properties & Surface Quality inherent in HR coils.No extraneous input of material for welding,besides advantage of latest forming & solid state HF Welding Technology. The High Pressure Line Pipe Manufacturing facility set up at its Jangalpur Works.Howrah, West Bengal produce HFW Pipes up to 20" diameter with thickness up to 14.3 mm for meeting the requirements mainly for long distance Transmission of High Pressure Oil,Gas and mineral slurry transmission,drilling Industries and other high test pressure applications.
