Introduction to Hot Rolled Steel Pipe

The product uses high-quality rolled plate. After it is proved to be qualified through review, it performs slitting, automatic molding and fusion welding. At the best fusion temperature under computer control, remove the burr inside and outside steel pipe and the steel pipe that is proved to be qualified after nondestructive test is heated up to 910°C-950°C and hardly oxidized. The descaling through multi-pass rolling of stretch-reducing mill make the metallographic structure, grain condition, geometric dimension and mechanical property of steel pipe uniform. The product carries out the standard of API SPEC 5L, API SPEC 5CT and EN10217 and is widely applied to flammable or nonflammable fluid transporting pipelines, boiler and steel structure. The product fills in domestic blank. There are four production lines with an annual production capacity of 200,000 tons ofφ89-φ630mm hot rolled steel pipe.
