1. Precision manufacturing: Cold-drawn seamless steel tubes are manufactured through the cold drawing process, which guarantees dimensional accuracy and smoothness. The surface has high finish, and the inner and outer walls are defect-free, meeting the requirements for high-precision applications.Our tolerance can be guaranteed at ±0.1mm.
2.Excellent mechanical properties: During the manufacturing process of cold-drawn seamless steel tubes, the material undergoes plastic deformation, resulting in grain refinement and improved hardness and strength. Compared to hot-rolled seamless steel tubes, cold-drawn seamless steel tubes have higher tensile strength, compressive strength, and impact resistance.
3.Good surface quality: Due to the characteristics of the cold-drawing process, cold-drawn seamless steel tubes have better surface quality. The surface is smooth and flat, with no obvious scales or oxidation, meeting the requirements for high-quality surface treatment and coating.
4.Wider range of applications: Due to its precision manufacturing and excellent mechanical properties, cold-drawn seamless steel tubes are widely used in industries such as mechanical manufacturing, automotive manufacturing, petroleum and natural gas industries, petrochemical industry, high-temperature and high-pressure fields, and structural engineering.
In summary, cold-drawn seamless steel tubes have advantages such as precision manufacturing, excellent mechanical properties, and a wider range of applications. Therefore, they are widely used in industries with high requirements for tube quality and performance.
