Product Description

Api 5Lx52 Seamless Steel Pipe raw material of seamless carbon steel pipe is round tube blank. The round tube blank shall be cut and processed by cutting machine, and the blank with a growth of about 1m shall be sent to the furnace for heating through conveyor belt. The billet is sent to 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 shall be pierced through the pressure piercer. Generally, the more common piercer is the cone roll piercer. This kind of piercer has high production efficiency, good product quality, large perforation diameter expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively rolled by three roll cross rolling, continuous rolling or extrusion. After extrusion, take off the pipe for sizing. The sizing machine rotates into the steel embryo at high speed through the conical drill to form a steel pipe.

The fluid pipeline is hollow steel pipe without weld from beginning to end. The steel pipe has a hollow section and is used as a pipeline for transporting a large amount of oil, natural gas, natural gas, water and some solid materials. Compared with solid steel (such as round steel), when the bending and torsional strength are the same, the weight of steel pipe is lighter. It is a kind of economical section steel, which is widely used to manufacture structural parts and mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle and so on. Scaffolds and steel scaffolds for construction.
