1. The hose and hose assembly can only be used to convey the designed materials, otherwise the service life will be reduced or invalid.
2. Correct use of the length of the hose, the length of the hose changes under high pressure (-4%-+2%) and the length change caused by mechanical movement.
3. The hose and hose assembly should not be used under pressure (including impact pressure) that exceeds the design working pressure.
4. Under normal circumstances, the temperature of the medium conveyed by the hose and the hose assembly should not exceed -40°C-+120°C, otherwise the service life will be reduced.
5. The hose and hose assembly should not be used under a small bending radius of the hose, and bending or bending near the pipe joint should be avoided, otherwise it will hinder the hydraulic transmission and convey materials or damage the hose assembly.
6. The hose and hose assembly should not be used in the torsion state.
7. The hose and hose assembly should be handled carefully, should not be dragged on sharp and rough surfaces, should not be bent and flattened.
8. The hose and hose assembly should be kept clean, and the inside should be rinsed clean (especially the acid pipe, spray pipe, and mortar pipe). Prevent foreign objects from entering the lumen, obstructing the delivery of fluids and damaging the equipment.
9. Hoses and hose assemblies that exceed the service period or storage period should be tested and identified before they can continue to be used.
