Precision seamless steel pipes are known for their high precision and strength, making them ideal for use in producing pneumatic or hydraulic components like cylinders. They are valued in the construction industry for their strong pressure resistance and lightweight properties. These pipes are primarily used to manufacture structural parts such as shafts and bars, as well as mechanical and other industrial components.
Applications of Precision Seamless Steel Pipes
Mechanical Parts:
General Use: Precision steel pipes are widely employed in the production of mechanical parts, including drill pipes, bolts, nuts, and springs.
Special Purposes:
Bearing Steel: Used for machine tool guide rails, gears, spindles (bearing steel), and various rollers, half-shafts (bearing-free steel).
Tool Steel: Includes alloy tool steel and carbide tool steel, used for making tools like bronze steel cones and various tool heads.
Spring Steel: Comprises ordinary spring steel for items like clock hands and wiring boards, and linear-resistant spring steel for manufacturing springs.
Gear Steel: High-strength gear steel and medium-carbon gear steel are used for making high-precision gears, such as those in aerospace engines.
Welding Wire: Includes low alloy welding wire for low-pressure boiler tubes and alloy welding wire for high-pressure boiler steam pipes.
Chemical Composition and Heat Treatment Requirements
- Chemical Composition:
The composition should adhere to the standards outlined in GB1591-79.
The carbon content must not exceed 0.10%.
For special-purpose pipes, the chemical composition should be determined based on specific requirements, with silicon and manganese content typically controlled between 0.55% and 0.75%.
- Dimensional Accuracy and Surface Quality:
Must comply with the standards specified in GB3639-83.
By meeting these chemical composition and heat treatment standards, precision seamless steel pipes achieve the necessary strength and durability required for various high-performance applications. These pipes play a critical role in ensuring the reliability and efficiency of mechanical parts and industrial components.
