Chemical composition analysis: By analyzing the chemical composition of the steel pipe samples, the content of each element can be determined to ensure that the steel pipe material meets the requirements of relevant standards and specifications.
Mechanical performance testing: By conducting tests such as tensile testing, impact testing, and hardness testing, the strength, toughness, and hardness of the steel pipe material can be evaluated.
Metallographic observation: By using a metallographic microscope, the grain structure, phase content, and grain boundary characteristics of the steel pipe can be observed to evaluate its structural properties.
Corrosion performance testing: By conducting tests such as salt spray testing and corrosion rate testing, the corrosion resistance of the steel pipe can be evaluated to ensure its service life in specific environments.
Dimension and appearance inspection: The dimension, shape, and surface quality of the steel pipe are inspected to ensure compliance with specified dimensional and appearance requirements.
Shandong Shanshui Special SteeI Group Co., Ltd . is a company specializing in seamless steel pipes, precision steel pipes, alloy steel pipes, boiler steel pipes, cold drawn steel pipes, spiral steel pipes, longitudinally welded pipes, seamless square pipes, welded square pipes, all raw materials All come from first class steel mills at home and abroad to ensure stable performance and quality of finished products.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.
