Production Process
The production of our hot-rolled precision seamless steel pipes follows a meticulous, multi-step process to guarantee quality and precision. The key stages include:
- Billet Preparation: High-quality steel billets are selected and preheated to the desired temperature for rolling.
- Piercing and Elongation: The billet is pierced to create a hollow tube, followed by elongation to achieve the desired length and diameter.
- Rolling: The tube is then passed through multiple rollers to reduce the wall thickness and obtain the required dimensions.
- Heat Treatment: The pipes undergo heat treatment to improve their mechanical properties, including tensile strength and hardness.
- Sizing: The pipes are sized to meet the exact specifications for outer diameter and wall thickness.
- Cooling and Finishing: The finished pipes are cooled, cleaned, and prepared for inspection.
- Final Testing: After the pipes are processed, they undergo a final round of tests, including non-destructive testing, before being certified for delivery.
