Cold-Drawn Cold-Rolled Seamless Steel Pipes/Tubes
Product Description: Cold-Drawn Cold-Rolled Seamless Steel Pipes/Tubes are manufactured through a process that involves rolling the steel at a controlled temperature to achieve a seamless structure. The cold-drawing process imparts a higher degree of dimensional accuracy and surface finish compared to hot-rolled or welded pipes. These tubes are known for their precise tolerances, smooth bore, and improved mechanical properties, making them suitable for applications requiring high strength and precision.
Advantages:
- High Precision: Close dimensional tolerances and smooth internal surfaces.
- Enhanced Mechanical Properties: Improved tensile and yield strengths due to the cold-working process.
- Improved Surface Finish: Reduced surface roughness, which can reduce friction in applications.
- Seamless Construction: No welds to weaken the structure or create points of failure.
- Uniform Wall Thickness: Consistent wall thickness throughout the length of the tube.
