The seamless steel pipe is characterized by no joints on the pipe wall, and obvious joints on ordinary pipes. Due to the small characteristics of seamless steel pipes, this pipe can be used in industry. Used and promoted in this field. Seamless steel pipes are mainly used for pipeline transportation, and can be used to transport certain fluids, such as energy. The transportation of oil and natural gas and some groundwater can be achieved through seamless steel pipes.
In modern society, the field and application range of seamless steel pipes have once again become a wide range of 16Mn seamless steel pipes. General seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel. The output is mainly used as pipelines or structural parts for conveying fluids.
Seamless steel pipes made of this steel are widely used in hydraulic props, high-pressure gas cylinders, high-pressure boilers, fertilizer equipment, petroleum cracking, automobile bushings, diesel engines, and energy transportation. Seamless steel pipes play an important role in them. effect. When talking about this type of pipe material, first of all, the strength is slightly higher, it is rarely quenched, and there is no temper brittleness.
Cold deformation has high plasticity and is usually used for bending, rolling, flanging and hammer arching. Arc welding and contact welding have good welding performance, the thickness is small during gas welding, and it is easy to crack on the parts with strict shape requirements or complex shapes. The machinability in the cold drawn or normalized state is better than that in the annealed state, and it is usually used in manufacturing where the stress is less and the toughness is higher.
