In the steel industry, seamless steel pipes, as an important pipe material, play an indispensable role in the industrial and construction fields. Among them, 45 seamless steel pipes, as a common material, have unique manufacturing processes and a wide range of applications.
1. Manufacturing process of 45 seamless steel pipes.
45 seamless steel pipes refer to seamless steel pipes made of 45 high-quality carbon structural steel. Its manufacturing process mainly includes the following steps:
-Raw material preparation: Select high-quality 45 steel as raw material to ensure the excellent performance of the product.
-Heating treatment: Heat the raw materials to a certain temperature to ensure the smooth progress of subsequent rolling and perforation processes.
-Piercing: Perforate the heated billet to form a pipe shape with a consistent wall thickness.
-Rolling: The billet after perforation is rolled to gradually thin the wall and gradually expand the diameter.
-Pickling: Pickle the rolled pipe to remove surface oxides and improve surface finish.
-Quenching and tempering: Through quenching and tempering treatment, the hardness and strength of the steel pipe are improved to ensure that its mechanical properties meet the standards.
2. Application fields of 45 seamless steel pipes.
45 seamless steel pipes have excellent mechanical properties and corrosion resistance, and are widely used in various fields:
-Mechanical manufacturing: As a steel pipe for mechanical structure, it is used to manufacture various mechanical parts, such as bearing sleeves, gears, etc.
-Petrochemical: Used to transport media such as oil and natural gas, and withstand work under high pressure and high-temperature environments.
-Automobile manufacturing: As an important material for automotive parts, such as exhaust pipes, transmission shafts, etc.
-Construction engineering: Used for support and load-bearing in building structures, such as bridges, building piles, etc.
-Aerospace: Also used in the aerospace field, such as aircraft engine parts, etc.
3. Characteristics and advantages of 45 seamless steel pipes.
