a sizzling rolled steel coil

 Confined fluid conveying with spiral seam submerged arc welding metal pipe (SY5036-83) is a sizzling rolled steel coil tube billet, usually spiral shape, with double-sided submerged arc welding method, welding, spiral seam metal pipe used for pressurized fluid metal tube is of high stress ability, the welding performance is good, through numerous strict scientific tests and exams, the use is protected and metal pipe is big,steel pipe astm a53 delivers excessive efficiency, and may save the investment of laying is principally used to hold oil and gas pipelines.

Their weight heavier quantity, coil internal diameter of 760mm normal pipe business favor to make use of after the straight hair quantity by cutting head, reduce tail, trimming and multi-go straightening, leveling and different ending line therapy, and then reducing board or heavy quantity, it becomes: hot-rolled steel, scorching-rolled metal coil leveling, slitting with other merchandise.

Particulars Hot-rolled sheet has low hardness, easy processing, and good ductility. Pre-bending and sizing are the main steps in the spiral tube forming process. By strengthening the method on the standard of the inspection, can eradicate the scratched substrate into the galvanized line. We manufacture and provide you all certified high quality merchandise. The high chromium content present in the materials allows the formation of an invisible chromium oxide film on the floor of metal.
