What is the relationship between hose length and water flow rate
PU steel wire hose is reinforced with spiral copper-plated steel wire. The steel wire is also coated with a layer of PU. The material is imported raw material, and the inner wall is smooth, which makes the material flow smoother. Compressible (expansion ratio is 1:4). The hose is light and soft, wear-resistant and mineral oil-resistant. It also has good weather resistance, ozone resistance and aging resistance. It is particularly suitable for dynamic suction and conveying working environments. Compared with steel wire hoses without PU outer layer, this process makes the hose have stronger bending tension. Halogen-free steel wire grounding can discharge static electricity.
During use, PU steel wire hoses rust and turn yellow during use. So what causes it?
Reasons for rusting of PU steel wire hoses
The structure of PU steel wire hose products is that the steel wire is embedded in the inner wall of the hose. A good quality pipe should be embedded tightly without gaps. There will be no room for substances such as air and water to enter. If the steel wire of the PU steel wire hose is not embedded tightly, it will have a great impact on the quality of the product. Because such a situation seriously affects the mission life of the PU steel wire hose. The main harm is that water and air can easily enter the place where the inlay is not tight.
Under the dual action of water and air, the copper-plated steel wire will rust. If the hose needs to have a certain extension and contraction movement, the friction between the hose and the pipe wall will increase. It is easy to cause unnecessary damage to the pipe wall. This will greatly affect the service life of the PU steel wire pipe.
