The quality of PU steel wire hose is closely related to production safety. How to inspect the quality of PU steel wire pipe? The hose engineer suggests testing from aspects such as color, feel, and inner diameter. Without any testing tools and conditions, we can roughly identify the quality of PU steel wire pipe based on visual, olfactory, tactile, and other senses.
1. The walls of high-quality PU steel wire pipes are clear and free of any impurities. The color of the defective PU steel wire hose turns yellow, which may be due to improper handling, decomposition, aging, or long-term improper storage during the production process. Observing the color, the PU pipe made of brand new material has a natural bright color on its surface, which feels very smooth.
2. Observe whether the pipe diameter is regular and whether the wall thickness is uniform. A high-quality PU steel wire pipe has a standard circular inner diameter and periphery, and the circular tube wall is evenly distributed.
3. High quality PU steel wire pipes have no odor of any other petrochemical products except for a slight plastic odor. And inferior PU steel wire pipes have an unpleasant and pungent smell of diesel, especially in hot summers where people cannot get close.
4. High quality PU steel wire pipes have smooth inner and outer wal, with a good feel, while low-quality pipes are relatively rough.
5. The structure of PU steel wire pipe products is that steel wires are embedded in the inner wall of the hose. High quality pipes should be tightly embedded without gaps, without giving room for substances such as air and water to enter. If the steel wires of PU steel wire pipes are not tightly embedded enough, water and air can easily enter the areas where they are not tightly embedded. Under the dual action of water and air, it can cause copper plated steel wires to rust. Due to certain expansion and contraction movements during use, This will increase the friction between the hose and the pipe wall, causing unnecessary damage to the pipe wall, greatly affecting the service life of PU steel wire pipes.
