What essential maintenance and preservation procedures must be implemented for metal hoses?

What essential maintenance and preservation procedures must be implemented for metal hoses?

1. The optimal storage temperature should be ≥15°C but not exceed 25°C. Temperatures below 0°C may cause rubber components to harden. Prior to application, allow them to acclimatize to 15–25°C.

2. Hoses must be shielded from direct or reflected sunlight, as well as intense artificial lighting.
3. Avoid storage under extremely high/low humidity conditions; maximum recommended relative humidity is 65% RH.
4. Ozone severely degrades most elastomers. Never store hoses near ozone-generating equipment. In high-ozone environments, minimize storage duration.
5. Stored hoses shall not contact oils, solvents, or any corrosive liquids/gases/vapors.
6. Certain elastomers degrade when exposed to copper alloys, or (to a lesser extent) manganese/iron compounds. Prevent contact with these metals or materials treated with their compounds (e.g., copper-naphthenate coated wood).
7. Avoid creosote-impregnated timber. Do not store against PVC materials due to plasticizer migration risks.
8. Implement pest control measures where bacterial/fungal growth or rodent infestation is anticipated.
9. High-pressure hoses should be stored loosely coiled with minimal stacking height to prevent deformation. Coil-stocked hoses must rest on their winding plane. Large-diameter hoses require horizontal placement on flat surfaces – never stack, especially with fittings attached.
