Product description

Highlights at a glance

  • Produced from high-quality carbon steel and alloy steel billets with stable material composition. Tested via non-destructive inspection to eliminate internal defects. Balanced mechanical properties resist deformation and cracking under continuous pressure, ideal for high-pressure hydraulic and pneumatic equipment.
  • Premium surface finish with smooth tube walls and low roughness to reduce fluid resistance and scaling. Custom inner & outer bright finishes available to skip polishing procedures. Widely used for hydraulic cylinders, precision instruments and automated equipment frames.
  • Higher dimensional accuracy than hot rolled tubes with precise OD & ID tolerances and good concentricity for controllable assembly clearance and better sealing. Perfect for bearing bushes, shaft sleeves and gear blanks to cut assembly loss and improve equipment stability.
  • Produced in accordance with GB, ASTM, DIN and other international standards. Complete material test reports and inspection certificates support export and project acceptance. Third-party inspection is acceptable with fully traceable quality for bidding projects.
  • Competitive pricing for bulk supply as direct manufacturer without middlemen. Fast delivery for stock goods. Pre-processing services such as facing, chamfering and deburring are offered so tubes can be directly processed upon arrival.
  • Widely applicable across construction machinery, automobile manufacturing, hydraulics, agricultural machinery, fitness equipment and petroleum machinery. Our technical team provides professional material and wall thickness selection support.
  • Customizable non-standard sizes, special tolerances and surface requirements. Flexible production schedule to meet special engineering needs. One-stop service covering drawing review, production, inspection and logistics for global buyers.
