Electric Resistance Welding (ERW) is a general term for Resistance welded steel tubes. ERW is the first letter of the corresponding English word.Resistance welded steel pipe can be divided into ac welded steel pipe and dc welded steel pipe.Ac welding according to the different frequency is divided into low frequency welding, if welding, super if welding and high frequency welding.High-frequency welding is mainly used for the production of thin-wall steel tubes or ordinary thick-wall steel tubes. High-frequency welding is also divided into contact welding and induction welding.Dc welding is generally used for small diameter steel tubes.

Therefore, generally speaking, high-frequency welded pipe is included in ERW welded pipe, which is a kind of ERW welded pipe produced by high-frequency welding process.ERW welded pipe is a kind of economical steel pipe with advanced performance and leading quality in the field of oil and gas storage and transportation.

ERW welded pipe is commonly used in the power industry to make wire sleeve. Performance characteristics: 100% ultrasonic testing of the base material ensures the internal quality of the pipe body;No uncoiling -- the working procedure of disc shears, the base material pressure pit, less scratches;There is basically no residual stress in the finished pipe after eliminating the stress;Short weld, low probability of defects;It can transfer wet and acidic natural gas conditionally.After enlarging, the geometrical dimension precision of steel pipe is high.After the molding is completed, the welding is carried out in a straight line in a horizontal position. Therefore, the control of the wrong side, slit and pipe diameter and circumference is better, and the welding quality is excellent.Tianjin China tong steel pipe co., LTD. Main product is divided into three categories: two straight seam steel pipe production lines, product specifications Ф Ф 114.3 mm - 508 mm, thickness 3.58 mm - 16.3 mm.Ten spiral pipe production lines, product specifications - Ф Ф 219.1 mm 3000 mm, thickness 5 mm to 30 mm.Two oil for oil casing production lines, product specifications - Ф Ф 60.32 mm 508 mm wall thickness of 4.24 mm to 16.3 mm.Supporting two anti-corrosion insulation production lines.The annual output of steel pipes is 500,000 tons.Product executable standards: API 5L, API 5CT, ASTM, en10219-2, GB/T9711, 3091-20081, 3793-2008, 14291-2006 and other international latest standards.The steel grades include GRB, X42, X52, X60, X65, X70, J55, K55, N80, L80, P110, etc.The products are widely used in petroleum, natural gas, coal mine, machinery, electric power, piling and other purposes.The company has selected international advanced technological equipment, such as w-ff molding, solid state high-frequency induction welding, ultrasonic inspection, magnetic flux leakage inspection, and high-end inspection instruments, such as metallographic analysis, vickers hardness tester, impact testing machine, spectrum analyzer, universal testing machine and so on.Since its establishment, it has obtained various international certification certificates and honorary qualifications, such as API 5L, API5CT, iso9002-2000 pressure pipeline production license, industrial product production license, China petroleum and petrochemical membership certificate, China high-quality product certificate, tianjin famous trademark, tianjin inspection-free products, tianjin top 100 private enterprises and other honorary qualifications.Products are exported to South America, North America, the European Union, southeast Asia and other places.Over the years by customers around the world.
