According to the material, hydraulic oil pipes are divided into high pressure steel wire braided hydraulic oil pipe and cloth covered rubber hydraulic oil pipe. Among them, steel wire braided hose is the most popular one. It has high strength and toughness. So it can withstand high pressure and impact loads. In a word, it is suitable for high temp and high pressure uses.
Different types of hydraulic oil hose
Hydraulic oil pipes are divided into low pressure hydraulic oil pipe and high pressure hydraulic pipe. The working pressure of low pressure hydraulic oil pipes is generally below 16MPa. And it is ideal for low pressure hydraulic systems, such as ships, agricultural machinery, etc. While the working pressure of high pressure hydraulic oil pipes is above 16MPa. And it is mainly used in high pressure hydraulic systems, such as machine tools, construction machinery, etc.
Hydraulic oil pipe design
The design of hydraulic oil pipes needs to consider many factors. While those include working pressure, flow, temp, vibration, corrosion, etc. The diameter and wall thickness of hydraulic oil pipes are the most critical parameters in design. And you should determine them based on working pressure and flow rate. In general, the smaller the diameter of the hydraulic oil pipe, the higher its working pressure. The wall thickness needs to be determined according to the strength and toughness of the hydraulic oil pipe material. Generally, it should be ensured that it is not easy to deform and break under the condition of withstanding working pressure.
Internal steel wire braid
The connection method of hydraulic oil pipes is also very important. It can be welding, ferrule and flange . The welding method is firm with good sealing. And it is suitable for high pressure systems. The ferrule is suitable for low pressure systems and is easy to install and replace. Flange is suitable for large diameter hydraulic oil pipes.
