Cooling water hose has a wide range of application
The quality of PU steel wire hose is related to the safety of production. How to test the quality of PU steel wire hose? You can start from the color, feel, inner diameter of the pipe, etc. Without any testing tools, we can roughly identify the quality of PU steel wire hoses based on vision, smell and touch.
5 methods to distinguish if the quality of PU duct hose is good
1. Observe if the pipe diameter is regular and if the wall thickness is uniform. Good quality PU steel wire pipes have a standard round inner diameter and outer circumference. The annular tube wall is evenly distributed.
2. The wall of high-quality PU steel wire pipe is crystal clear and free of any impurities. The defective PU steel wire hose is yellow in color. It may because of decomposition, aging due to improper handling during the production process, or improper storage for a long time. Looking at the color, the surface of the PU pipe made of new materials has a natural bright color and feels very smooth.
3. Except for a little plastic smell, high-quality PU steel wire pipe does not have any smell. The inferior PU steel wire pipe has an unpleasant and pungent diesel smell. Especially in the hot summer, people can’t get close.
4. The high-quality PU steel wire pipe has smooth inner and outer walls and good hand feel. Low-quality tubes are rougher.
5. The structure of PU steel wire pipe products is that the steel wire embeds in the inner wall of the hose. Good quality pipes are tightly inlaid and have no gaps, leaving no room for air, water and other substances to enter. If the steel wire of PU steel wire pipe is not tightly inlaid enough, it will have a great impact on the quality of the product. Because this situation seriously affects the mission life of PU steel wire pipe.
The main hazard is that water and air can easily enter where the mounting is not tight. Under the dual action of water and air, copper-plated steel wires will rust. If the hose needs to expand and contract to a certain extent during use, 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 PU steel wire pipe.
