ERW pipe (also called ERW steel pipe) is the abbreviation Electric Resistance Welded Pipes. Electric resistance welding refers to a group of welding process (including spot and seam welding) that produce coalescence of faying surfaces where heat to form the weld is generated by the electrical resistance of material combined with the time and the force used to hold the materials together during welding. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.

Applications

For low pressure fluid transmission, such as water pipelines, agriculture & irrigation (water mains, sewerage systems,industrial water lines, deep tube-wells & casing);

For machinery manufacturing, such as engineering purpose, fencing, scaffolding, line pipes etc.;

For Gas pipe lines (pipe lines for natural gas), LPG and other non-toxic gas.
