SMOOTH BORE
Cold drawn welded tubes with H9 inner diameter tolerance from offer precise dimensional accuracy, high concentricity, and excellent surface finish, meeting UNI EN 10305-2 standards. The production process involves controlled strip thickness, cold deformation, and high-frequency welding without altering the chemical composition. Cold drawing refines the surface to 0.8 micron Ra roughness, enhancing quality for hydraulic cylinders. Rigorous testing ensures top-tier performance. These tubes are ideal for precision applications requiring superior dimensional control and surface quality.

HYDRAULIC LINE PIPE
HPL Tubes are seamless cold-drawn precision steel tubes primarily used as pressure lines in hydraulic or pneumatic systems. These tubes experience fluctuating stresses due to changes in velocity and pressure of the medium under operating conditions, leading to pressure surges that combine with static internal pressure. The design of these tubes must account for the actual stress conditions experienced during service. For applications requiring reduced weight or high operating pressures, specialized solutions are available. Additionally, there are options for enhanced corrosion protection to ensure long-term durability. These tubes comply with the EN 10305-4 standard for hydraulic and pneumatic systems and available in E355/E235 +N.
