Hydraulic Tube – Welded Steel EN 10305-2, Cold Drawn / ERW, Precision Tubing for High-Pressure Systems

Our Welded Hydraulic Tubes are produced from cold-drawn or ERW-welded strip steel in compliance with EN 10305-2 precision tube standards.They provide excellent dimensional control, straightness, and surface quality, making them suitable for hydraulic systems, pneumatic equipment, and industrial machinery.Compared to seamless tubes, welded tubes offer a cost-effective alternative for applications where extremely high-pressure resistance is not critical but dimensional accuracy and surface quality are still required.
