1. Product Overview
Cold drawn seamless pipe is a type of precision seamless steel pipe produced by cold drawing process after hot rolling base material. The whole pipe body is integrally formed with no welding joint. Compared with hot rolled pipes, it has tighter dimensional tolerance, flatter inner and outer surfaces, and more stable performance. It is a preferred material for fields requiring high precision and good surface finish.
2. Materials & Executive Standards
Main materials: Carbon steel, alloy steel, 20#, 45#, Q345B, 15CrMo etc.
Compliance standards: GB/T 8162, GB/T 8163, ASTM A106, DIN, EN series standards.
All raw materials are strictly screened to guarantee overall product quality.
3. Key Features
High precision: Accurate outer diameter and wall thickness, small dimensional deviation.
Smooth surface: Bright inner and outer wall, no burrs, low fluid resistance.
Excellent mechanical performance: High strength, good toughness and wear resistance.
Stable structure: Uniform metal texture, not easy to deform under stress.
Good machinability: Easy for cutting, bending and further deep processing.
4. Main Applications
Hydraulic cylinders, pneumatic components and high-precision pipeline systems
Mechanical manufacturing, auto parts and bearing accessories
Instrumentation, electrical equipment and precision machinery
Food, medical and light industrial pipeline projects
- Construction and fine processing engineering
5. Quality Inspection & Service
Every product undergoes strict dimensional inspection, mechanical performance test and non-destructive testing. Complete quality certificates can be provided. We offer multiple sizes and lengths, and accept custom specifications, surface treatments and OEM services to meet diverse customer demands.
