Manufacturing Process & Advantages
Hot Rolling Production Process
- Hot rolling → Heating → Piercing
- Three roller helical rolling, tandem rolling or extrusion
- Tube knockout → Sizing or tube diameter reduction
- Cooling → Straightening → Water pressure test
- Labeling → Warehousing
Performance Advantages
Our hot rolling process refines steel crystalline grains and eliminates microstructure defects, resulting in:
- Enhanced mechanical performance
- Denser microstructure along rolling direction
- Superior intensity and structural integrity
- Improved reliability for high-pressure applications
