Advantage
Precision seamless tube is a kind of high precision steel tube material after cold-drawn or hot-rolled treatment. Since precision steel tube has no oxidation layer on the inner and outer walls, bears high pressure without leakage, high precision, high finish, no deformation in cold bending, flaring, flattening without cracks and other points, it is mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless tubes or welded tubes. Compared with solid steel such as round steel, it is lighter in weight when the bending and torsional strength is the same, and is an economic cross-sectional steel, widely used in the manufacture of structural parts and mechanical parts.
Features
1. High precision, saving the loss of material when machining users.
2. Many specifications, wide range of applications.
3. High precision, good surface quality and straightness of cold rolled finished products.
4. The inner diameter of steel pipe can be made into hexagonal shape.
5. Steel pipe performance is more superior, the metal is more dense.
