Producers Proportion Demystify The Reasons Of Metal Twine Expansion Hose Corrosion

Many customers reflect that the steel wire expansion pipe bought back is corroded, what is the reason for this? Let for you to explain!

Steel wire expansion tube is made of steel wire presence, 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 steel wire expansion tube from being corroded? We can use paint or oxidation-resistant metal for plating to ensure the carbon steel surface, but, as people know, this protection is only a film. If the protective layer is broken, the steel underneath will begin to rust.

In fact, the corrosion of steel wire tubing is mainly due to the chromium content within the steel wire, the higher the chromium content the more corrosive it is! This oxidized layer of the steel wire expansion tube is 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.
