Pu Polyurethane Hose Manufacturers Share Why Pu Polyurethane Hose Is Corroded

Many customers reflect that buy back the pu polyurethane hose is corroded, what is the reason? Let zhongwang hose editor for you to explain!

pu polyurethane hose inside is by the presence of steel wire, once the steel wire disclosure, it is quickly oxidized by the air, so that the corrosion continues to expand, and ultimately the formation of holes. So, is there a way to keep the pu polyurethane hose from corrosion? We can utilize paint or oxidation-resistant metals for plating to secure the carbon steel surface, but, as is well known, this protection is only a film. If the protective layer is broken, the steel underneath begins to rust. 

In fact, the corrosion of pu urethane hose is mainly due to the chromium content within the steel wire, the higher the chromium content the greater its corrosiveness! This oxide layer of pu urethane hose is extremely thin, through which the natural luster of the stainless steel surface can be seen, giving stainless steel a unique surface. Moreover, if the surface layer is damaged, the exposed steel surface will react with the atmosphere for self-repair, re-form this "passivation film", continue to play a protective role.
