Description:
St37.4/52.4 Hydraulic Steel Tubing – Product Overview
Engineered for high-performance hydraulic circuits, the St37.4/52.4 steel tubing delivers precision, durability, and adaptability across a wide range of industrial applications. Combining superior material properties with advanced manufacturing techniques, this tubing ensures efficient fluid transmission, ease of integration, and long-term reliability in demanding environments.
Key Features
High-Quality Material
Made from St37.4/52.4 grade steel, this tubing offers an optimal balance of strength, ductility, and pressure resistance. Its excellent weldability and machinability allow for easy fabrication and secure integration into complex hydraulic systems.
Precision Dimensions & Smooth Surface
Manufactured to tight tolerances with a uniformly smooth internal surface, the tubing minimizes flow resistance and pressure loss. Optional oiled finishes or custom surface treatments further enhance installation ease and hydraulic efficiency.
Size Flexibility & Customization
Available in a wide range of diameters and wall thicknesses, the tubing can be cut to custom lengths to fit specific system layouts. This reduces material waste and simplifies installation in space-constrained applications.
Durability Under High-Pressure Conditions
Designed to withstand high operating pressures and dynamic loads, the tubing maintains structural integrity and leak-free performance even in rigorous hydraulic applications.
Typical Applications
Construction Machinery: Hydraulic systems in excavators, cranes, loaders, and bulldozers
Automotive and Mobile Equipment: Hydraulic circuits in trucks, agricultural vehicles, and specialty machinery
Industrial Systems: Used in manufacturing, pressing, and material handling equipment
Oil & Gas Applications: Suitable for hydraulic controls in drilling, extraction, and processing machinery
Quality Assurance
Each batch of tubing is produced and tested in accordance with international hydraulic tubing standards, ensuring consistent performance, dimensional accuracy, and material reliability.
