The length of the hose assembly is determined based on the installation conditions. Potential shortening or elongation under pressure should be considered according to applicable hose standards.
Before installing the hose and hose assembly, an inspection should be conducted to ensure that the inner wall of the hose is clean and free of blockages, and that the fittings are free of foreign matter, burrs, or rough edges. Surface defects, especially those on the fitting core, pose a risk of leakage and should be avoided.
To ensure that the lifespan of the hose assembly is not shortened due to additional load, the installation of the assembly should generally meet the following requirements:
1. Avoid twisting the hose
2. In addition to the hose's own weight, minimize the extra tension the hose experiences during operation.
3. The hose should not be installed below the minimum bending radius.
4. When installing by bending, the bending radius of the hose should begin at a length of 1.5d (d is the hose diameter); otherwise, a hinged support will occur.
5. Take appropriate measures to prevent external mechanical damage to the hose assembly.
6. Avoid applying additional load to the hose by using appropriate fittings or connectors.
7. If the hose assembly shifts or bends at the same water surface, proper installation can prevent hose twisting.
8. When using moving parts in a hose assembly, the hose assembly should not be less than the minimum bending radius throughout its entire range of motion and should not be subjected to additional tensile loads.
9. When clamping the hose, avoid using clamps that impede the hose's natural movement and length changes.
10. Pressure caused by vibration should be reduced to a minimum and avoided as much as possible. If the hose assembly is connected to a rigid component, appropriate clamps should be used and placed as close as possible to the connection.
11. The hose should be protected from heat radiation (e.g., near the exhaust system). In high-temperature locations, the hose can be protected with a heat shield or heat insulation material.
