Carbon steel pipes & tube (CS pipe) are made of steel ingots or solid round steels through perforation into capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in my country's steel pipe industry.
Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel. Generally, a large amount of alloying elements are not added, and it is sometimes called ordinary carbon steel or carbon steel. Carbon steel, also known as carbon steel, refers to an iron-carbon alloy with a carbon content of less than 2% WC. In addition to carbon, carbon steel generally contains small amounts of silicon, manganese, sulfur, and phosphorus. Generally, the higher the carbon content of carbon steel, the greater the hardness, the higher the strength, but the lower the plasticity.

Types of carbon steel pipes:
Carbon steel pipes can be divided into seamless steel pipes, straight seam steel pipes, spiral pipes, high frequency welded steel pipes, etc.
1) Hot rolled (extruded) seamless steel pipe : round tube billet → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → stripping → sizing (or reducing) → cooling → straightening → hydraulic test (or Flaw detection) → marking → storage
2) Cold drawn (rolled) seamless steel pipe: round tube blank→heating→piercing→heading→annealing→pickling→oiling (copper plating)→multi-pass cold drawing (cold rolling)→blank tube→heat treatment→straightening →hydrostatic test (flaw detection)→marking→storage
Carbon steel seamless pipes are divided into two types: hot-rolled (extruded) seamless steel pipes and cold-drawn (rolled) seamless steel pipes due to their different manufacturing processes. Cold drawn (rolled) tubes are divided into two types: round tubes and special-shaped tubes.
