Anti Corrosion 32 Inch ASTM A53 GrA API 5L GrB ERW CS Pipe

Outer Diameter : 114.3mm - 812.8mm ( 4 "- 32 " ) API 5L GrB ERW Carbon Steel Pipe

API 5L ERW Steel Pipes means Electric Resistance Welded Pipes. API 5L ERW steel pipe 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.Huayang can manufacture API 5L ERW Steel Pipe from diameter 1inch to 26inch with various thickness. Our ERW pipe not only used as API 5L line pipe, but also as ASTM A252 piling pipe and A53 GR B fluid pipe or EN 10219 structure pipe.

ERW carbon steel pipe is the hot rolled coil through the continuous roll forming, the use of high-frequency current skin effect and proximity effects, so that the edge of the coil heat fusion, pressure in the squeeze roller under pressure welding to achieve production. Therefore, erw carbon steel pipe residual stress is small, through the weld heat treatment, sizing, straightening, water pressure and other processes, the residual stress to further release and reduce. Practice has proved that erw carbon steel pipe in the storage and use of residual stress on the steel pipe does not affect. Without any welding wire, the weld in the physical properties and chemical composition with the plate exactly the same. The quality of the erw carbon steel pipe depends on the quality of the sheet.
