Best ERW Welded Steel Pipe and Tubes, Spiral Welded Steel

ERW Welded Steel Pipe is produced by electric resistance welding method, from raw material of hot rolled or cold rolled steel plate, steel coils. There is a straight weld seam on both inside and outside surface of the tube body, so that we call it welded steel tube. The inside weld seam can be removed or not removed, depending on customer's order. Best ERW Welded Steel Pipe and Tubes, Spiral Welded Steel LASW WELDED STEEL PIPE, LASW Welded Steel Tube, with the production method of longitudinal welded arc welding. ERW Welded Steel Pipe is produced by electric resistance welding method, from raw material of hot rolled or cold rolled steel plate, steel coils.

Difference Between Seamless And Erw Pipe

The welded seam of electric weld pipe is heat-treated after welding to a minimum temperature of 1,000°F or processed so that no untempered martensite remains. Such differences of erw are usually eliminated if the electric-weld tubing is heat-treated by the quenched-and-tempered process, which is mandatory for API grades L80, C90, T95, and P110.

ERW Steel Pipe

As the ERW steel pipe with easy control of rolling, with the welding technology and on-line heat treatment technology, the performance of the weld can be controlled, so straight seam welded steel pipe elongation than seamless steel pipe 8% -10% higher, which Is because the straight seam electric-welded pipe carbon content of less than 12% lower than the seamless tube. Electric Resistance Welded (ERW) Pipe Manufacturing Permanent Steel Manufacturing Co. is one of the leading manufacturers and suppliers of ERW tubes in China. We are also one of the largest exporters of ERW pipes in China. ERW pipe stands for resistance welded pipe. According to customer requirements, we can manufacture ERW steel pipes of different sizes and shapes.

Electric Resistance Welded (ERW) Pipe Manufacturing

The electric resistance welding pipe is manufactured by cold forming a piece of steel plate into a cylindrical shape, and then passing an electric current between the two edges of the steel plate to heat the steel plate to a point of force, forcing these edges to form a weld that was not initially used Fill the material, but use low frequency alternating current to heat the edges. Electric Resistance/ Fusion Welded (ERW and EFW)ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.

Electric Resistance/ Fusion Welded (ERW and EFW)

Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond. Meanwhile with the combined pressure, the edge of the pipe billet steel melted and extruded together.
