electric resistance welding erw welded carbon steel pipe

Carbon Steel Welded and ERW Pipe manufacturer India

The Spiral Welded Carbon Steel Pipe is produced from coils of the same material. For added strength and distributed joints, the coils are welded from end to end spirally and make stronger pipes. For larger pipe sizes, the electric resistance welding is used. The Carbon Steel ERW Pipe can range up to 120 inches in outer diameter. During the ERW

Common Defects of ERW Steel Pipe Welding

Aug 29, 2016 · ERW steel pipe is fed into the molding machine, deformed into a cylindrical tube through an induction loop or contact welding angle, the magnetic field around the induction coil current is induced by the edge of the strip, the strip edge due to its resistance generated thermal resistance is heated, the heated extruded strip edge forming roll extrusion welds. Differences Between Electric Resistance Welding and Jan 02, 2020 · High-quality steel pipes require heat treatment on the weld line or off-line to refine the microstructure of the weld zone. The weld of the high-quality ERW welded pipe can reach the same level of toughness as the base metal, which cannot be achieved by the submerged arc welding process. EFW is the abbreviation of electric fusion welding.
