Flexible Hose Can Improve The Corrosion Resistance
1, watch the tube weaving effect, do not jump, broken, stacked silk. The higher the density of the weaving pattern, the better the weaving density, the higher the density of the weaving layer, the smaller the pore size, the lower the density.
2, to see whether the body material is stainless steel, the higher the grade of stainless steel, the stronger the corrosion resistance. How to distinguish the level of stainless steel grades, just use stainless steel to identify the syrup can be detected, generally detected 304 stainless steel wire is relatively high.
3, view the other parts of the material and quality. Such as nuts, the core is copper fittings, copper nuts whether the process is polished chrome, whether the surface glitches and so on. Finally, look at whether the 304 steel is the material, the same approach as above, look at the stamping effect is rough. In short the material is better, craft quality.
4, with the nose smell the mouth will be issued if the piercing gas, the higher the amount of glue within the tube, the higher the puppy the higher the opposite. The higher the amount of glue, the better the quality of the tube, pull, blasting and other properties are also strengthened.
Causes of Flexible Hose corrosion
Metal and atmospheric oxygen reaction will form an oxide film on the surface. In the ordinary carbon steel on the formation of iron oxide continue to oxidation, so that corrosion continues to expand, and ultimately the formation of holes. The surface of the carbon steel can be secured by painting with paint or oxidation resistant metals (eg zinc, nickel and chromium), but, as is known, this protection is only a film. If the protective layer is damaged, the following steel will begin to rust.
The corrosion resistance of stainless steel Flexible Hoses depends on the chromium content. When the chromium content is increased to 10.5%, the corrosion resistance of steel is significantly increased, but the corrosion resistance is improved even when the chromium content is higher Not obvious. The reason is that when the steel is alloyed with chromium, the type of surface oxide is changed to a surface oxide similar to that formed on pure chromium metal. This tightly adhered chromium-rich oxide protects the surface from further oxidation. This oxide layer is extremely thin, through which it can see the natural gloss of the stainless steel surface, so that stainless steel has a unique surface. Moreover, if the surface damage, the exposed steel surface and the atmosphere will be self-repair, re-formation of this "passive film", continue to play a protective role.
1, the installation should be considered: the Flexible Hose can not bend less than the minimum bending radius of the Flexible Hose, rough surface or sharp corner of the Flexible Hose will cause wear and tear, the total length of the Flexible Hose should be able to ensure that both ends of the Flexible Hose potential movement.
2, the Flexible Hose to reverse (should avoid the Flexible Hose to reverse, should be relative to moving parts may lead to reverse the use of the correct installation to avoid).
3, bending radius is too small (choose a reasonable form of joints, to avoid less than the minimum bending radius of the installation. Do not within 1.5 times the range within the sleeve from the beginning of bending the Flexible Hose).
4, external damage (to avoid and may cause the outer layer of wear or damage to the object contact, when applied to the mobile state, please pay special attention to set the length of the Flexible Hose to avoid tension or wear).
