Carbon Steel Pipe is made of steel ingot or solid round steel through perforation, and then hot rolled, cold rolled or cold drawn. Carbon steel pipe plays an important role in the steel pipe industry.
The raw material of carbon steel pipe is round tube blank. The round tube blank is cut by the cutting machine, and the blank with a length of about 1 meter is sent to the furnace for heating through the conveyor belt. The billet is sent into the furnace for heating at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Temperature control in furnace is a key problem After the round tube blank is discharged from the furnace, it should be pierced through the pressure piercer. Generally, the more common piercer is the cone roll piercer, which has high production efficiency, good product quality, large perforation expansion, and can pierce a variety of steel grades. After piercing, the round tube blank is successively cross rolled, continuous rolled or extruded by three rolls. After extrusion, the pipe shall be removed for sizing. The sizing machine rotates the conical drill bit into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the sizing machine bit. After sizing, the steel pipe enters the cooling tower and is cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydrostatic test) by the conveyor belt for internal flaw detection. If there are cracks, bubbles and other problems inside the steel pipe, they will be detected. Steel pipes should be strictly selected by hand after quality inspection. After the steel pipe is inspected, the number, specification, production batch number, etc. shall be sprayed with paint. And hoisted into the warehouse by crane.
