Because of the complex variety of hydraulic hose, the structure is diverse, and the use of different conditions, so the length of the service life of the hose, not only depends on the quality, but also depends on the correct use and maintenance. So even if the product has very high quality, if not correctly used and maintained, it will seriously affect its use quality and life, and even cause undue serious accidents, causing losses to property. The following points are provided for attention:
1, hose and hose assembly can only be used for conveying designed materials, otherwise it will reduce the service life or failure.
2, the correct use of hose length, hose in high pressure length change (-4%-+2%) and mechanical movement caused by the length change.
3. The hose and hose assembly shall not be used under pressure (including impact pressure) exceeding the design working pressure.
4. Under normal circumstances, the medium temperature transported by the hose and hose assembly should not exceed -40℃-+120℃, otherwise the service life will be reduced.
5. the hose and hose assembly should not be less than the minimum bending radius of the hose, avoid bending or bending near the pipe joints, otherwise it will hinder the hydraulic transfer and conveying materials or damage the hose assembly.
6 . hose and hose assembly, should not be used in the state of torsion.
7 . the hose and hose assembly should be carefully handled, should not be dragged on the sharp and rough surface, should not be bent and compressed.
8. hose and hose assembly should be kept clean, the internal should be washed clean (especially acid pipe, spray pipe, mortar pipe). Prevent foreign objects from entering the cavity, blocking the conveying fluid and damaging the equipment.
9. over the service period or storage period of the hose and hose assembly to be tested and identified before continuing to use.

Hydraulic hose alias hydraulic tubing, hydraulic hose, high pressure hose, hydraulic pipe, steel wire high pressure pipe, steel wire braided hose steel wire winding hose, generally divided into steel wire braided hydraulic hose and steel wire winding hydraulic hose
Hydraulic hose according to the material of rubber material and rubber and plastic material two categories. According to the production process, it is divided into steel wire braided hose, steel wire winding hose, wire braided hose and cloth clip hose
1. Hydraulic hose structure: mainly composed of liquid resistant synthetic rubber inner layer, middle layer, multi-layer reinforcing layer and weather resistant synthetic rubber outer layer.
The inner rubber layer has the function of making the conveying medium withstand pressure and protecting the steel wire or wire fiber from erosion. The outer rubber layer protects the reinforcement layer from damage. The reinforcement layer is the skeleton material, and its function is to ensure the use pressure of the hose.
2. hydraulic hose use: Mainly used for mine hydraulic support, oil field development, Suitable for engineering construction, lifting, transportation, metallurgy forging press, mining equipment, vessels, injection molding machinery, agricultural machinery, all kinds of machine tools and various industrial departments mechanization and automation of hydraulic system with certain pressure and temperature of oil in the base (such as mineral oils, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water) and liquid Move. Rubber and plastic material of hydraulic hose, also known as rubber and plastic hose, is a new type of hose, its corrosion resistance and energy saving effect is obvious.
3. hydraulic hose working temperature: -40℃ ~ 120℃ four, product specifications range: DN2.5mm ~ DN305mm.
