Seamless carbon steel pipe is a type of steel pipe manufactured by piercing steel ingots or solid billets, followed by hot rolling, cold rolling, or cold drawing. It plays a crucial role in my country’s steel pipe industry. The production process includes billet heating, pressure piercing, rolling and extrusion, sizing and cooling, and flaw detection and quality inspection. The primary raw material is round billets, processed using equipment such as tapered roller piercing machines. The final product undergoes rigorous mechanical property testing and surface quality inspection.
