What To Consider When Selecting Hydraulic Tubes?

Hydraulic tubes are pipes used to transmit hydraulic pressure, which is divided into two types: hard pipe and soft pipe. ‌Hard pipe is mainly seamless steel pipe, while soft pipe is a pipe formed by layered wire mesh and rubber bending.

Hydraulic tube material

‌Hydraulic tube materials are usually divided into the following types: carbon steel, stainless steel, copper, aluminum alloy, etc. Material selection is important, but when selecting materials, it is also necessary to select the corresponding material according to the element composition of the working environment to ensure the service life and safety and reliability of the pipe.

1. Carbon steel hydraulic tube: suitable for transmitting liquids with low pressure, and the operating temperature is generally between -40℃ and 120℃. The corrosion resistance is relatively poor, it is easy to be corroded into holes, the service life is short, and it is easy to corrode in humid environments.

2. Stainless steel hydraulic tube: suitable for transmitting high-pressure liquids, gases, corrosive media, etc. It has very good corrosion resistance and long service life, but the elastic modulus is smaller than that of carbon steel, so the strength is slightly lower, and it is easy to deform when the operating temperature is too high.

3. Copper hydraulic tube: suitable for transmitting low-pressure liquids and oils, and has good electrical conductivity. It is widely used in fuel and oil transmitted by hydraulic systems.

4. Aluminum alloy hydraulic tube: suitable for transmitting low-pressure liquids, gases, steam and other media. Aluminum alloy hydraulic tubes have good thermal conductivity, light weight, high strength and good corrosion resistance.

Hydraulic tube size

The selection of hydraulic tube size involves not only the pipe diameter, but also factors such as wall thickness and inner diameter. It is necessary to select different pipe diameters and pipe sizes according to the actual working scene to ensure that it can meet the working pressure and flow requirements within the safety control range.

The diameter setting of the hydraulic tube should take into account both the working pressure requirements and the transportation loss. The larger the pipe diameter, the more severe the loss. Therefore, the selection of pipe diameter needs to be weighed and selected according to the actual situation and specific needs.

Hydraulic tube connection method

There are many ways to connect hydraulic tubes, such as pipe flange connection, clamp connection, threaded connection, elbow connection, etc. The selection of different connection methods needs to be combined with the actual situation, according to the use scenario and the expected pressure, temperature, vibration and other factors. At the same time, when selecting the pipe connection method, it is necessary to take into account its applicability, reliability, maintainability and other factors for comprehensive consideration.

Maintenance of hydraulic tubes

Hydraulic tubes are easily affected by external environment, working pressure and other factors during long-term use. Regular maintenance and repair can be used to extend the service life of hydraulic tubes and ensure work efficiency and safety.

During the use of hydraulic tubes, attention should be paid to the support of the pipes, and excessive bending and swinging should be avoided during use to avoid damage to the pipes.

Summary

For those who are uncertain about the selection of hydraulic tubes or do not have a deep understanding of hydraulic tubes, a detailed understanding of the material, size and connection method of hydraulic tubes is of great reference value for solving real-time problems, improving work efficiency and delaying the service life of hydraulic tubes.
