Carbon steel round tube is a hollow cylindrical tube made of carbon steel. Carbon steel is an alloy consisting primarily of iron and carbon, with small amounts of other elements such as manganese, silicon, and copper. The round tube shape refers to the cross-sectional shape of the tube, which is circular. Carbon steel round pipes are available in various sizes and thicknesses to meet different requirements. They can be produced by processes such as seamless or welded manufacturing.

Details Of Gnee Carbon Steel Round Pipe

(1) Hot rolling (extruded seamless steel pipe): round tube billet → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → tube removal → sizing (or reducing) → cooling → straightening →Hydrostatic test (or flaw detection) → marking → storage
(2) Cold drawn (rolled) seamless steel pipe: round tube blank→heating→perforation→heading→annealing→pickling→oiling (copper plating)→multi-pass cold drawing (cold rolling)→blank tube→heat treatment→Straightening→hydrostatic test (flaw detection)→marking→warehousing
