How to distinguish the quality of high pressure hoses from appearance

When choosing high pressure hoses, besides choosing a trustworthy manufacturer, how to distinguish the quality of the high pressure hoses from the appearance is very important. Next, let's talk about the way to distinguish the quality of high pressure hoses from the appearance:

1. Look at the outer surface of the rubber of the high pressure hoses

To distinguish the quality of the high pressure hoses, the first thing to be observed is the outermost rubber surface of the high pressure hoses. First of all, it is necessary to see whether the surface layer is flat and smooth, whether there is blistering or potholes, and whether the thickness is consistent. Hydraulic hoses with a smooth surface and a consistent thickness is better.

2. Look at the reinforcement layer of the high pressure hoses

By observing the cross-section of the high pressure hoses, you can see the cross-section of the three-layer structure, and you can well distinguish the quality of the high pressure hoses. First, look at the gloss of the overall section, and the brighter quality will be better; then you need to observe the section of the steel wire layer to see whether the braiding and winding of the steel wire layer is even and the thickness of the steel wire layer, the thicker the steel wire diameter, the higher the quality.

3. Look at the inner rubber layer of the high pressure hoses

The inner rubber layer directly endures the pressure and corrosiveness of the conveying material, so the quality of the inner rubber layer greatly affects the overall quality of the high pressure hoses. What needs to be observed in the inner rubber layer is whether the wall thickness is even. In addition, it is necessary to pinch whether the steel wire layer and the inner rubber layer are closely connected and elastic. The quality of the high pressure hoses with tight connection and good elasticity are better.

4. Other identification methods

In addition to the methods mentioned above, it can also be judged through professional tests, such as stability tests to see whether the working pressure meets the standard, and whether the airtightness of the inner and outer layers of rubber meets the requirements.
