Introduction:
In the realm of hydraulic systems, where precision and reliability are paramount, the DIN 1630 2391 ST37.4 Hydraulic Tubing stands as a testament to engineering excellence. This tubing is meticulously crafted to meet the stringent demands of modern hydraulic applications, offering high precision and low surface roughness to ensure optimal performance in diverse industrial settings.
Key Features：
High Precision & Tight Tolerances
Produced in compliance with DIN 1630 and DIN 2391 standards, these tubes are manufactured to exceptionally tight dimensional tolerances and high geometric accuracy. The use of ST37.4 grade steel ensures excellent machinability and uniform internal and external dimensions, guaranteeing seamless compatibility with hydraulic fittings and pumps for leak-free, reliable connections.
Low Surface Roughness
Featuring an exceptionally smooth internal surface, these tubes significantly reduce fluid friction and mechanical wear in hydraulic systems. This low surface roughness not only improves operational efficiency but also minimizes the risk of particulate accumulation, preventing system contamination and extending the service life of hydraulic components.
Seamless Construction
The seamless manufacturing process eliminates weld seams and potential weak points, ensuring uniform structural integrity along the entire tube length. This construction method provides superior leak resistance even under high-pressure conditions, while maintaining consistent material strength and reliability.
High Strength & Durability
ST37.4 mild steel offers high tensile strength and excellent fatigue resistance, making these tubes ideal for high-pressure hydraulic applications. Their robust mechanical properties ensure reliable performance under constant pressure cycles, minimizing the risk of failure in demanding operating conditions.
Corrosion Resistance
With inherent moderate corrosion resistance, these tubes are suitable for environments exposed to moisture and mild corrosive elements. For more aggressive conditions, optional surface treatments or coatings can be applied to enhance protection and extend service life.
Versatile Applications
Widely used in mobile and stationary hydraulic systems across multiple industries, these precision tubes are ideal for applications in automotive manufacturing, construction machinery, industrial equipment, and fluid power systems. Typical uses include hydraulic cylinders, pumps, valves, and high-pressure fluid transmission lines.
