Strong Strength, High-Quality Products
hydraulic steel pipe

The hydraulic 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. 

Advantages of hydraulic pressure

Compared with mechanical transmission and electrical transmission, hydraulic transmission has the following advantages:

1. Various components of hydraulic transmission can be arranged conveniently and flexibly according to needs.
2, light weight, small size, small movement inertia, fast reaction speed.
3, easy control, can achieve a wide range of stepless speed regulation (speed range up to 2000:1).
4, can automatically realize overload protection.
5, the general use of mineral oil as the working medium, the relative movement surface can be self-lubricating, long service life;
6, easy to achieve linear motion /
7, it is easy to realize the automation of the machine, when the electro-hydraulic joint control, not only can realize a higher degree of automatic control process, but also can realize remote control.

Hydraulic Steel Pipe Description

Cold-rolled precision seamless steel pipe is made of seamless steel pipe finished pipe or seamless pipe waste, after pickling, phosphating, saponification treatment, and then rolled by cold rolling machine into hydraulic steel pipe.The hydraulic 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 tube with close dimensional tolerances, increase material strength and enhanced machinability. Therefore, hydraulic tubes are suitable in high performance piping system application.

What is the material of hydraulic tube?

There are two type of material grade, 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.
