Information

High pressure hydraulic steel tube is designed to convey liquid fluids to among hydraulics components, fittings, valves, flanges, and other tools. It is made of material E355 (ST 52.4) or E235 (ST 37.4). These two grades have different chemical composition. This helps to control the working pressure. 

The hydraulic steel tube is cylinder-like shaped tubing device that when attach to hydraulic systems, allow for the passage of fluids within and among components. The tube standard specifies dimensions for cold drawn finishing and ​seamless precision steel tubes. Cold drawn process provides the hydraulic steel tube with close dimensional tolerances, increase material strength and enhanced machinability. Therefore, hydraulic steel tubes are suitable in high performance piping system application. 

There are two type of material grade for high pressure hydraulic steel tube, ST52.4 and ST37.4. ST52.4 is high tensile strength tube means it has higher permissible working pressures by reduced tube wall thickness, and leading to reduced system overall weight. Please refer to chemical composition for ST52.4 and ST37.4 tube material:
