Product Description

    Seamless steel pipe is a steel pipe made by piercing a whole round steel without any weld on the surface, which is called a seamless steel pipe
      Characteristics of precision specification products
1. Smaller outer diameter.
2. High precision for small-scale production.
3. Cold drawn finished products have high precision and good surface quality.
4. The cross-sectional area of steel pipes is more complex.
5. Steel pipes have superior performance and denser metal.
3. Cold drawn finished products have high precision and good surface quality.
4. The cross-sectional area of steel pipes is more complex.
5. Steel pipes have superior performance and denser metal.

     Precision steel pipes have high dimensional accuracy, smooth inner and outer surfaces, and no oxide film on the inner and outer surfaces after heat treatment. The steel pipes have no cracks when expanded or flattened, and do not deform during cold bending. They can withstand high pressure and undergo various complex deformations and mechanical deep processing treatments
