1
. Seamless steel pipe for structure (GBT8162-2008). Mainly used for general structure and mechanical structure. Its representative material (brand): carbon steel, 20, 45 steel; alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.
2
. Seamless steel pipes for conveying fluids (GBT8163-2008). It is mainly used for conveying fluid pipelines in engineering and large-scale equipment. The representative material (grade) is 20, Q345, etc.
3
. Seamless steel pipes for low and medium pressure boilers (GB3087-2008) are used to manufacture various structures of low and medium pressure boiler superheated steam pipes, boiling water pipes and superheated steam pipes, large smoke pipes, small smoke pipes and arch bricks for locomotive boilers Hot-rolled and cold-drawn (rolled) seamless steel pipes of high-quality carbon structural steel for pipes. The representative material is 10, 20 steel.
Main application
I. Oil pipeline
In the process of oil and natural gas exploration and exploitation, carbon steel seamless steel pipe is an important pipeline material for transporting oil and gas. Due to its high temperature resistance, corrosion resistance, pressure resistance and other properties, it makes it resistant to high temperature, corrosion and pressure. Therefore, carbon steel seamless steel pipe is widely used in oil and gas transmission pipelines.
Manufacturing machinery and equipment
Another application area of carbon steel seamless steel pipe is in the process of mechanical production. In mechanical equipment, carbon steel seamless steel pipe is widely used, such as automobiles, motorbikes and mechanical equipment, exhaust piping, bearing piping, cold, heat exchangers and a variety of piping connections. It can ensure the quality of products and has good reliability.
3、Building structure
Carbon steel seamless steel pipe can be used in building structure, such as frame structure, bridge structure, ship structure and so on. Because of its high strength, good rigidity, strong corrosion resistance and other characteristics, it makes it widely used in the construction field. Especially in the steel structure building, carbon steel seamless steel pipe has replaced the previous ordinary pipe, accelerating the process of construction.
Hot rolled carbon steel seamless steel pipe production process
The raw material of seamless carbon steel pipe is a round tube blank, which is cut by a cutting machine into a billet with a length of about 1 meter, and sent to a furnace for heating through a conveyor belt. The billets are fed into the furnace and heated at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a critical issue. After the round tube blank is released from the furnace, it is pierced through a pressure punching machine. Generally, the more common punching machine is the conical roller punching machine. This kind of punching machine has high production efficiency, good product quality, large amount of perforation and diameter expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively cross-rolled, continuously rolled or extruded by three rolls.
