ERW steel pipe "is a straight seam resistance welding pipe, English Electric Resistance Welding, abbreviated simply referred to as ERW, for transporting oil, gas and other vapor-liquid objects meet high and low voltage requirements, the current conveying pipe in the art world accounted pivotal position.
welded steel plates welded pipe, into a high-frequency electric resistance welded (ERW steel pipe), the arc straight seam welded (the LSAW), spiral pipe. of ERW represented resistance welding, resistance welding, with high efficiency, low cost, material savings, ease of automation and other characteristics, it is widely used in various industrial sectors aviation, aerospace, energy, electronics, automobiles, light industry, is one of the important welding process.
ERW steel pipes due to the use of hot-rolled coil as a raw material, wall uniform thickness can be controlled within ± 0.2mm, APl steel ends according to U.S. standards or GB / T9711.1 standard repair play side groove, the advantages of definite length delivery, etc. in recent years, natural gas in each gas pipe network and the company has been widely adopted as a major ERW steel pipe distribution network of steel pipe.
ERW pipes means Electric Resistance Welded Pipes. ERW steel pipes and tubes are used. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.
While manufacturing ERW steel pipes, only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel is used. High performance ERW steel pipes and tubing possess high strength corrosion resistance, high deformability, high strength and high toughness. ERW pipes and tubes stands for Electric Resistance Welded pipes and tubes.
