ERW Steel Pipe & ERW Casing - Welded Steel Pipe, Seamless

ERW Pipe. High-frequency straight seam electric-resistance welded steel pipe ( erw steel pipe) is hot-rolled coil after forming machine, the use of high-frequency current skin effect and proximity effects, the tube edge heating and melting, squeeze roller under pressure welding to achieve production. High-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same, ERW Steel Pipe API 5L ASTM A53-Threeway Steel Co.Pipe Type:HFI Steel Pipe, EFW Steel PipeHFW Steel Pipe Welded Steel Pipe Application:Gas, heating, water Transportation, construction, mechanical application, aviation,offshore platform etc Specification:OD:OD:33.4-660mm WT:WT:2.1-22mm LENGTH:0.8-18m Standard:API SPEC 5LASTM A53ASTMA252EN10219EN10217JIS G3444 ERW Steel Pipe, China Electrical Resistance Welded Pipe ERW steel pipe is a straight seam electric resistance welded pipe, a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe. It has sturdy frame which is strong enough to make sure the stable operation. And it is resistant to water, oxygen and corrosion, which is endurable with long life span.

The selective and localized corrosion prefers to occur in the weld, especially close to the fusion line.

Cold finished pipe made by a series of operations in which the flat rolled material is cold shaped into tubular form and welded at the seam by the application of pressure and heat. The heat is generated at the seam by the resistance to the flow of electric current applied through electrical contacts Semi Bright ERW Round Tube - Handy Steel StocksSemi Bright Square is Electric Resistance Welded round tube which has a typical steel grey appearance and a suitable surface for general applications. It is ideal for furniture making and powder coating where high quality finishes are required.

Stainless Steel ERW Pipe SS 304/316 Welded Pipe

Electric resistance welding is a process of welding metal parts together by getting them to contact and heating them with electric current. This is one of the most widely used processes in making stainless steel pipes. In this method, the pipe is made from a strip of stainless steel material.ERW Pipes, HFW Pipe Manufacturer & SupplierD 508 steel in the range from 101.6 max OD of the pipe end can not be larger than the DN of 1%D; smallest OD than the DN shall be 1% D.
