ERW pipe means electric resistance welded pipe, and it is a resistance welding by 10-500 kHz of high-frequency current. The raw material of the ERW steel pipe is hot rolled steel coil made of steel billet, and the usual material is Q195, Q215, Q235, Q355 in China ERW pipe grade, which are same material with S195, S235, S355 in Europe, and SS400 in Japan.(plate) ERW Pipe & Tube Manufacturers in India, Buy ERW Steel no surface treatment s235jr erw black welded steel pipe(steel) ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24 OD. In the process of manufacturing ERW pipes, steel strips in designated sizes are pulled through a series of rollers and formed into a tube which is
EN 10219 10210 S235JR ASTM A500 Gr.B Carbon Steel Seamless Rectangular Steel Tubing & Welded Square tube . Application . Natural gas, petroleum, chemical industry, electric power, metallurgy thermodynamic fields, water supply engineering, steam heating, hydroelectric power station and long pipeline transportation projects and so on.(plate) Manufacturer quality large diameter welded steel pipe for no surface treatment s235jr erw black welded steel pipe(steel) The steel pipe has a longitudinal weld, and the internal and external welds are welded by a submerged arc welding. 5. After the overall mechanical reaming treatment, the internal stress of the steel tube is small and evenly distributed, which can effectively prevent the stress corrosion cracking, with high dimensional accuracy, and facilitate no surface treatment s235jr erw black welded steel pipe
ERW (Electric Resistance Welded) pipe is a straight seam electric resistance welded pipe, a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe, which is commonly used for oil, gas, water transmission, machinery manufacturing, etc. It has sturdy frame which is strong enough to make sure of the stable operation. And it is resistant to water, oxygen and corrosion no surface treatment s235jr erw black welded steel pipe
The LSAW steel pipe is the steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. Usually divided into ERW steel pipe, electric welded thin wall pipe, transformer cooling tubing and so on. Direct seam welded pipe production process is simple, high production efficiency, low cost, rapid development.(plate)S235JR welded pipe
