The corrosion resistance of stainless steel metal hose depends on the content of chromium, when the amount of chromium, 10.5%, the atmospheric corrosion resistance of steel increased significantly, the pharmaceutical industry with a metal hose international brands, but at a higher chromium content , although still improve corrosion resistance, but not obvious. The reason is that when chromium steel alloying process, the type of change has become similar to the surface of the oxide surface oxides formed on pure chromium metal. Chromium-rich oxide protective surface that closely adhered to prevent further oxidation. This thin oxide layer, through which you can see the natural luster of the stainless steel surface, so the stainless steel has a unique surface. Moreover, if the surface is damaged, the pharmaceutical industry with a metal hose excellence, and atmospheric response has exposed the steel surface will self-repair, re-formation of this 'passive film', continue to play a protective role. Prospects metal hose: Our country is producing and exporting countries metal hose, metal hose with the pharmaceutical industry, which, in global sales of metal hose, mostly from China's production and exports, China has become the the world's leading supplier of metal hose. Although China's large-scale metal hose industry, but due to technical innovation capability is weak, the market structure is too simple, weak brand influence and other factors, many metal hose production companies often lack the core competitiveness of the pharmaceutical industry with a metal hose from produced self-marketing, it is difficult bigger and stronger. Stainless steel hose sales of 14.5 billion yuan, of which the proportion of stainless steel hose threading less than 25%, not only with the international market structure far hose products, can not meet the growing demand for domestic manufacturing stainless steel hose. Professional production of the pharmaceutical industry with a metal hose, hose Hao Peng, the pharmaceutical industry by Ning County Hopen stainless steel metal hose metal hose Limited. Ning County Hopen stainless steel metal hose Limited (www.haopengguanye.com) (www.haopengguanye.com) is Dezhou, hoses leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness , the maximum meet customer needs. In Hopen hose leadership with the staff warmly welcome all inquiries negotiations to create Hopen hose better future.
