With the development of the economy, high-pressure rubber hoses, hose accessories and other products have become one of the commonly used accessories in daily industry. But various problems may also arise during use, especially whether the high-pressure hose can work properly under high-pressure conditions and its accessories. Whether there will be impact rupture requires that the steel wire braided rubber hose and hose accessories meet the inspection requirements and strictly comply with the operating specifications.

The rubber hose should meet the following requirements: the burst pressure should reach 2.5 times the working pressure; The test pressure needs to reach 1.5 times the working pressure and maintain this pressure for more than 2 minutes without damage; The pulse pressure should be within the range of zero to working pressure, with 50000 pressure pulses without damage. Due to the widespread use of rubber hoses in various industries, and the harsh working conditions of rubber hoses, it is important to pay attention to quality when selecting rubber hoses to avoid accidents.

CHARACTERISTICS

1. Made of special synthetic rubber, it has excellent heat resistance, oil resistance, and aging resistance.

2. High pressure resistance and excellent pulse performance.

3. Has excellent bending resistance and fatigue resistance.

4. The pipe material is soft, tightly connected to the body, and has minimal deformation under pressure.

5. The fixed length of the steel wire braided rubber hose is 20 meters, and it can be made according to requirements within 50 meters.

2、 Reasons and preventive measures for impact and rupture

1. The reinforced layer of the rubber hose does not rust, but irregular breakage may occur. If the hose ruptures, peel off the outer adhesive layer and check if the reinforcement layer is rusted, but there are irregular broken wires along the length of the reinforcement layer. The main reason is that the rubber hose is subjected to high-frequency impact.

2. If the hose breaks or is about to break due to external force or system overload, the orthopedic method can be used.

3. The rubber hose is broken, and the braided steel wire near the breakage is rusted. If it ruptures, peel off the outer adhesive layer and check if the steel wire woven or wrapped near the rupture is rusted. This is mainly due to the influence of moisture or corrosive substances on the outer rubber layer, which weakens the strength of the hose and leads to its rupture under high pressure.

The steel wire braided rubber hose consists of an inner rubber layer, a middle rubber layer, four or more layers of alternately wound steel wire reinforcement layers, and an outer rubber layer. The main structure uses nitrile rubber with good oil resistance as the main raw material, synthetic rubber mixed with special reinforcing agents as the inner rubber layer, and special steel wire as the braided reinforcement layer. The outer rubber layer uses synthetic rubber with excellent weather resistance.
