Cold drawn irregular seamless steel pipe
2024.11.15
Cold drawn irregular seamless steel pipes include those with non-circular cross-sectional profiles, equal wall thickness, variable wall thickness, variable diameter and variable wall thickness along the length direction, symmetrical and asymmetrical cross-sections, etc.
Product features:
- Cold rolled formed steel allows for local buckling of the cross-section, thereby fully utilizing the bearing capacity of the member after buckling; Hot rolled steel does not allow local buckling of the section.
- The reasons for the generation of residual stress in hot-rolled and cold-rolled steel sections are different, so the distribution on the cross-section also varies greatly. The residual stress distribution on the section of cold-formed thin-walled steel is bending type, while the residual stress distribution on the section of hot-rolled or welded steel is thin film type.
- The free torsional stiffness of hot-rolled steel is higher than that of cold-rolled steel, so the torsional resistance of hot-rolled steel is better than that of cold-rolled steel.
Cold drawn special-shaped seamless steel pipe, general material: 10 # 20 # 45 # Q345B (16mn) 20cmmo
Cold drawn special-shaped seamless steel pipes have relatively high precision and a smoother surface than ordinary drawn steel pipes, saving costs and making them the preferred choice for the mechanical industry.
