ERW Steel Pipe—Electric Resistance Welded Steel Pipe is made of hot-rolled steel coils/sheets that have been put in a process know as cold roll forming. The obvious advantage of ERW steel pipe compared to seamless steel pipe is the uniform wall thickness. According to API standard or GB/T9711.1 standard, both ends of the steel pipe are beveled and length can be fixed as required.
Electric Resistance Welded Steel Pipe Usage: Used for low pressure liquid delivery, such as water, gas, and oil. Oil drilling and machinery manufacturing, etc.

The rating standards for the API 5L ERW Steel Pipe under PSL1 type and PLS 2 type. The maximum out diameter we can do is 610mm.
High-frequency welded pipes are generally straight-slit, but straight-slit welded steel pipes are not necessarily high-frequency welded. The high-frequency straight-slit electric resistance welded steel pipe is formed by the skin effect and the proximity effect of the high-frequency current after the hot-rolled coil plate is formed by the molding machine, and the edge of the tube blank is heated and melted, and pressure welding is performed under the action of the pressing roller to realize the production. The high-frequency resistance welded steel pipe is different from the ordinary welded pipe welding process. The weld is made of the base material of the steel strip body, and the mechanical strength is better than that of the general welded pipe. The surface is smooth, high precision, low cost, and has low weld seam height, which is beneficial to the coating of 3PE anti-corrosion coating.
Different steel pipe would have its special production method, so that they would have multifarious characters. Today, we would like to talk about black ERW steel pipe among welded steel pipe. 1)It is a kind of steel pipe made by hot-rolled coil through the molding machine; 2)Main production method would be high-frequency; 3)Compared with ordinary welding steel pipes production technology, black steel pipe has better technical on body melting, mechanical strength; 4)Black ERW steel pipe has features of smooth appearance, high precision, low cost welding seam height and so on.
