Key features of EN10305-certified tubes include:
- High dimensional accuracy: Tolerances as tight as ±0.05 mm for critical applications.
- Superior surface quality: Smooth finishes (Ra ≤ 0.4 μm) reduce friction and wear in hydraulic/pneumatic systems.
- Enhanced strength: Cold working increases tensile strength and hardness while maintaining ductility.
- Consistency: Strict adherence to EN10305 standards guarantees uniformity across batches.
Technical Advantages of ANBAO Hydraulic Steel Tube
1.Precision for Demanding Applications:
EN10305 cold drawn tubes are engineered for industries where even a micron-level deviation can lead to system failures. Their unmatched dimensional stability makes them ideal for:
- Hydraulic cylinders: Leak-proof performance under high pressure.
- Fuel injection systems: Seamless fluid transfer in automotive engineering.
- Bearings and bushings: Reduced friction for longer component life.
2.Material Versatility
These tubes are available in a range of steel grades, including E235, E355, and stainless steel variants, to suit diverse operational environments. Whether your project requires corrosion resistance, high-temperature tolerance, or weldability, EN10305-certified suppliers can tailor solutions to meet exact specifications.
3.Cost-Efficiency Through Durability
The cold drawing process eliminates porosity and internal defects, resulting in tubes that withstand extreme stress and cyclic loading. By minimizing maintenance and replacement costs, EN10305 tubes deliver long-term value—especially in industries like aerospace, energy, and heavy machinery.
