Product description

Highlights at a glance

  • High strength & high pressure resistance: Welded-free design, more uniform overall performance, resistant to high pressure and less prone to leakage.
  • High dimensional accuracy: Especially for cold-drawn tubes, the dimensional control is precise, making them suitable for precision mechanical equipment.
  • High-temperature resistance and corrosion resistance: Suitable for high-temperature and corrosive environments such as boilers, heat exchangers, petrochemicals, etc.
  • Long service life: The combination of high-quality raw materials and precise craftsmanship ensures safer and more reliable operation over the long term.
  • Strong processability: Easy to be processed by deep techniques such as cutting, drilling and welding.
    • Certifications & compliance
