What is a thick-walled seamless carbon steel pipe?Thick-walled seamless carbon steel pipe refers to a carbon steel pipe produced by seamless processes (such as hot rolling, cold drawing or extrusion), with a large wall thickness to pipe diameter ratio (usually wall thickness/outer diameter ≥ 0.05). Since there is no weld, its structure is more uniform and its strength is higher, suitable for high pressure, high load or harsh environment.Production process:Hot rolling method:...
