(1) Current status of the metal hose profession

      First, the cost of production has risen too fast, the raw materials have generally risen, the cost of labor has risen too fast, the problems of labor difficulty labor shortage are very prominent, the wages of employees in coastal areas such as the Yangtze River Delta the Pearl River Delta have generally risen. The above two "costs rise too fast" have kneaded the profitability of metal hose companies.

     Secondly, metal hose enterprises still bear heavy burdens. The fees charged by enterprises are still excessive high, illegal illegal charges still exist. For example, some local borrowing fees may alleviate financial difficulties, some of them use the power to charge to obtain some benefits, some grassroots law enforcement officers may charge illegally to obtain personal benefits.

     The third is that since last year, in order to firmly respond to the financial crisis, China has implemented a prudent monetary policy. It has improved the bank deposit reserve ratio for 12 consecutive times the reduction of credit planning has caused small medium-sized metal hose companies, especially small micro metal soft The difficulty of financing for management companies has further increased. Many small medium-sized metal hose companies have urgently dealt with private fake loans. The loan interest rate has reached 50% -100%, the financing cost remains high. In 2010, China's current financial system was unable to deal with the “bottleneck” of small metal hose companies with fewer financing channels, smaller planning, higher cost constraints.

     Fourth, most of the small medium-sized metal hose companies are at the low end of the traditional industrial value chain. Weak technological innovation, extensive production operation, low equipment levels, shortage of professional personnel, lack of independent intellectual property rights brands, mainly rely on "low cost, low price, "Low-profit" participation in competition makes it difficult to digest the factors of rising operating costs in a timely manner, to adapt to the practical requirements of changing development methods adjusting optimizing the economic structure.

     The metal the oxygen in the atmosphere react to form an oxide film on the surface. The iron oxide formed on the ordinary carbon steel continues to oxidize, causing the rust to continue to expand eventually form holes. Paint oxidation-resistant metals (for example, zinc, nickel, chromium) can be used for electroplating to ensure the appearance of carbon steel, but, as is known, this maintenance is only a thin film. If the maintenance layer is damaged, the underlying steel begins to rust.

 The corrosion resistance of stainless steel hose depends on the content of chromium. When the amount of chromium is added to 10.5%, the atmospheric corrosion resistance of steel is significantly added, but when the chromium content is higher, although the corrosion resistance can still be improved, it is obvious . The reason is that when alloying steel with chromium, the type of surface oxide is changed to similar to that formed on pure chromium metal. This tightly adhered chromium-rich oxide maintains the appearance avoids further oxidation. This oxide layer is extremely thin, through which you can see the natural luster of the stainless steel appearance, so that stainless steel has a common appearance. Moreover, if damaged

 (2) Development prospects of the metal hose profession

     China is a major producer exporter of metal hoses. Among them, most of the metal hoses sold worldwide are produced exported China. China has become the world's leading supplier of metal hoses. Although China's metal hose industry is relatively large, many metal hose manufacturers often lack central competitiveness are difficult to grow bigger stronger due to factors such as weak technological innovation capabilities, overly monolithic shopping mall structure, weak brand influence.

    The sales volume of stainless steel hoses is 14.5 billion yuan, of which the threaded stainless steel hoses account for less than 25%, which is only far the structure of hose products in international shopping malls, but also cannot meet the growing demand for stainless steel hoses in domestic manufacturing.

In 2010, the unbalanced structure of metal hoses meant that the produced hoses were out of line with demand. For example: users need a large gap in optical fiber maintenance hoses, but galvanized metal hoses are overproduced; modern manufacturing industry urgently needs double-buckle stainless steel hoses with a large gap, but low-grade single-buckle stainless steel hoses are overproduced.
