Storage conditions of rubber hose products

When we use a kind of product, we also need to master its related storage knowledge. In many cases, it is due to our improper storage of its products, which causes damage to it. The same is true for the storage of rubber tube products. Many problems are Special attention needs to be paid to:

1. For the storage of rubber tube products, it is recommended to store them at 10 degrees Celsius to 25 degrees Celsius. Note: Do not store the rubber tube at a temperature above 40 degrees Celsius or below 0 degrees Celsius.

Special care should be taken when moving rubber hoses below -15°C. The rubber tube should not be stored near the heat source, and the relative humidity should not exceed 65%.

2. Its storage should not be exposed to light. The storage room for storing rubber tubes should be kept dark, especially avoid direct sunlight or strong artificial light on the rubber tubes. If storage rooms have windows or any openings covered by glass, they should be screened.

How to distinguish the quality of high pressure hose

The high-pressure hoses that we commonly see on the market are good or bad, but if you want to distinguish them, I will teach you a few simple methods, let’s take a look:

1. First check the outer rubber of the high-pressure hose, whether its surface is smooth and flat, whether there are bubbles, bumps, sponges, trachoma, etc.; when impounding, use a peeling machine to remove the rubber to see if the stripped rubber is continuous Yes, continuous is good quality.
2. Look at the brightness of the section of the rubber hose from the outside, the one with high brightness is the top grade, and the gelatinous layer should be pinched with nails, and the gelatin has good elasticity.
3. From the cross section of the hose, whether the steel wire layer inside is uniform or not, it can be distinguished from the diameter of the steel wire. The steel wire mesh of the rubber hose is evenly distributed, and there is no missing weaving place. The thicker the diameter of the inner steel wire, the better.
4. Check whether the thickness of the pipe wall of the inner rubber layer is uniform, and the size of the inner hole of the rubber pipe, and you can tell it by trying a standard joint.
5. Pass the pressure test. The national standard requires that the test pressure is twice the working pressure, and the burst pressure is generally 3-4 times the working pressure.
