(Summary description)How to extend the service life of high pressure hose?

The service life of the hydraulic hose assembly depends on its usage conditions. In order to prolong the service life of the high-pressure hose, the hose assembly in use should be checked regularly for leaks, kinks, blistering, scratches, abrasion, or other damage to the outer rubber layer. When the assembly is found to be damaged or worn, it must be replaced immediately. The service life of the assembly can be extended by the following measures:
1. Use factors:

1. Installation of the hose assembly: The installation of the hydraulic hose assembly should comply with the relevant standards of SAEJ1273 on the direction and arrangement of hydraulic hoses to ensure that the hose assembly is used correctly.
2. Working pressure: The pressure of the hydraulic system should not exceed the rated working pressure of the hose. The pressure rise or peak value that exceeds the rated working pressure is extremely destructive and must be considered when selecting a hose.
3. Minimum burst pressure: The burst pressure mentioned in this catalog is limited to destructive tests to determine the design safety factor.
4. Temperature range: Do not use the hose under temperature conditions (including internal and external temperatures) exceeding the recommended limit. If the hydraulic fluid used contains emulsion or solution, please refer to the relevant technical data separately. Regardless of the operating temperature range of the hose, it must not exceed the maximum operating temperature recommended by the fluid manufacturer.
5. Fluid compatibility: The hydraulic hose assembly (inner rubber layer, outer rubber layer, reinforcement layer and hose joints) must be compatible with the fluid used. Proper hoses must be used because the chemical properties of phosphate-based and petroleum-based hydraulic fluids are completely different. Many hoses are suitable for one or more fluids, but not all fluid types.
6. Minimum bending radius: Do not bend the hose to less than the recommended minimum bending radius, nor subject the hose to tension or torque. This may cause the reinforcement layer to withstand excessive stress and greatly reduce the hose's ability to withstand pressure .
7. Hose size: The size of the hose (inner diameter) must be able to handle the required flow rate. If the inner diameter is too small at a specific flow rate, it will cause excessive fluid pressure and heat generation, causing damage to the inner rubber layer.
8. Hose direction arrangement: The hose should be restrained, protected or guided (use pipe clamps when necessary) to minimize the risk of damage to the ring caused by excessive bending, shaking, or contact with moving parts or corrosive substances. Determine the appropriate hose length and joint form to prevent wear, avoid contact with sharp objects and twist, so as to achieve a leak-proof connection. .
9. Hose length: When determining the correct hose length, the length changes under pressure, machine vibration and movement, and when the hose assembly is wired should be taken into consideration.
10. Hose application: Choose the appropriate hose according to the specific application.
2. Environmental factors:
The storage environment, together with the rubber material, can change the storage life of the hose. The specific service life is difficult to quantify because there are many factors that affect the hose. If the storage measures are proper, the storage life can reach 3-5 years. Beyond this time, the service life of the hose will be greatly reduced, depending on various factors in the storage environment, including:
1. Temperature: The hose should be stored in a cool and dry place, and the temperature must not exceed +100°F (+38°C). If it is stored at a temperature below freezing point, it may need to be preheated after being taken out before it can be processed, tested and put into use.
2. Direct sunlight, rain, heater or close to electrical equipment.
3. Humidity and ozone.
4. Oil, solvent, corrosive materials or flue gas.
5. Insects or rodents.
6. Radioactivity.
7. Available space and whether there is bending.
Three, storage factors
1. The hose should be stored in the original container. Don't pile it too high, otherwise its own weight will crush the bottom hose.
2. It is recommended to perform visual inspection and testing before using hoses that have been stored for a long time. Hoses judged to be in bad condition should be replaced to avoid failure, property damage or personal injury. The warehouse shall be managed according to the first-in first-out principle. Excessive storage time and poor environment will cause the hose grade to drop, performance degradation and premature failure.
