Information

    According to the use, it is mainly divided into: threading hose, drainage hose, ventilation hose, shower hose, wire harness pipe. One of the common ones is the one used in the bathroom, that is, the shower hose. What are the characteristics of the hose? Will the hose corrode? I believe you are interested in understanding, so here is a brief introduction for you.

 

What are the characteristics of the hose?

    Hose is an important part in modern industry. The hose is mainly used as wire, cable, wire and cable protection tube of automatic instrument signal and civil shower hose, with specifications from 3mm to 150mm. Small diameter hose (inner diameter: 3mm-25mm) is mainly used for the protection of sensing circuit of precision optical ruler and industrial sensor line. According to Jiuzheng pipe network, the main features of hose are as follows:

1. Flexible between pitch.
2. It has good flexibility, no obstruction and rigidity.
3. Light weight, good consistency of caliber.
4. Flexibility, repeated bending and good flexibility.
5. Good corrosion resistance and high temperature resistance.
6. Rat bite proof, good wear resistance, to prevent internal wire wear.
7. It has good bending resistance, tensile property and lateral pressure resistance.
8. Soft and smooth, easy to thread, install and locate.

 

Will the hose corrode?

    After the metal reacts with oxygen in the atmosphere, an oxide film is formed on the surface. The iron oxide formed on the common carbon steel continues to be oxidized, which makes the corrosion expand and finally forms holes. Carbon steel surfaces can be guaranteed by electroplating with paint or oxidation resistant metals (e.g., zinc, nickel and chromium), but, as is known, this protection is only a thin film. If the cover is damaged, the steel below will start to rust.

    The corrosion resistance of stainless steel hose depends on the content of chromium. When the content of chromium reaches 10.5%, the atmospheric corrosion resistance of steel increases significantly, but when the content of chromium is higher, the corrosion resistance can still be improved, but it is not obvious. The reason is that when the steel is alloyed with chromium, the type of surface oxide is changed to that similar to that formed on pure chromium metal. This tightly adherent chromium rich oxide protects the surface from further oxidation. This kind of oxide layer is very thin, through which we can see the natural luster of the surface of stainless steel, so that the stainless steel has a unique surface. Moreover, if the surface layer is damaged, the exposed steel surface will react with the atmosphere to repair itself and form the "passive film" again to continue to play a protective role.

 

    The above is what characteristics of the hose and hose corrosion, I believe you will have more understanding after reading it, the content is only for your reference, I hope it can help you.
