ERW steel pipe is short for Electric Resistance Welded pipes, used for transporting oil, gas and liquid ETC, which can meet the various requirements as high or low pressure, and currently ERW steel pipe occupies a pivotal position in the field of conveying pipe all over the world.
1.Welded pipe is referring to the common "submerged arc welding steel pipe," marked "SC" electrical engineering, can be used for water and gas pipe can also be threading pipe, thick.
2. Line pipe, wire and tube, it's thin and can only used for threading pipes.
3. ERW pipe is "high-frequency resistance welding steel tube", unlike ordinary welded pipe welding process, welding seam is composed of steel belt ontology of parent metal melting and mechanical
strength than the general welding control.
ERW steel pipe has performances as high production efficiency, low cost, save material, easy automation, etc. Therefore it was widely used in various industry sectors, aviation, aerospace, energy, electronics, automobile, light industry and so on. Nowdays, it is one of the important welding process.
