The so-called high pressure is to set this requirement. According to the pressure of the system, determine the maximum working pressure of the high pressure hose. Each hose has a normal working pressure. The explosion pressure of the hose is 3-4 times the working pressure. The greater the pressure, the stricter the number of steel wire layers and product production. Therefore, according to the actual pressure of the system, select the max working pressure of the high pressure pipe. In this way, the normal operation of the system can be guaranteed and the appropriate pressure hose can be selected.
If the system impacts pressure frequently, a hose with a long pulse life should be selected. At the same time, the working pressure of the selected hose should be appropriately increased.
Temperature is also one of the factors considered by customers. The working environment temperature of the high-pressure hose is too high or too low, which will affect the service life and carrying capacity of the hose. Therefore, the hose should be used within the allowable range. Systems that are not within the allowable range for a long time should use hose sheaths or purchase special hoses. If it is a special medium, it is necessary to ensure that the inner and outer layers, joints, and sealing rings of the hose are compatible with the medium. Appropriate end connection: Because the nut connection is convenient, low cost, and widely used. However, in the case of large vibration, the loosening of the nut should be fully considered, and flange connection can be considered.
Fluid compatibility The fluid in the hose should meet the use requirements of the product sample. Exceeding the prescribed use cannot guarantee the service life and safety of the pipeline.
