Flexible metal hose manufacturer


Flexible metal hose is an important connecting component in engineering technology. It is composed of corrugated flexible pipe, mesh sleeve and joint. It is produced by flexible metal hose chinamanufacturer. As compensation element, sealing element, connecting element and shock absorber in various gas and liquid pipeline systems and length, temperature, position and angle compensation systems, it is applied in aerospace, petrochemical industry, mine electronics, mechanical shipbuilding, medical and health, textile electronics, energy construction and other fields.


Flexible metal hose, which is produced by Flexible metal hose china manufacturer, is an important connecting component in engineering technology. It is composed of corrugated flexible pipe, net sleeve and joint. As compensation element, sealing element, connecting element and shock absorber in various gas and liquid pipeline systems and length, temperature, position and angle compensation systems, it is applied in aerospace, petrochemical industry, mine electronics, mechanical shipbuilding, medical and health, textile electronics, energy construction and other fields. The latest national standard for flexible metal hoses is General Technical Conditions for Corrugated flexible metal hoses (GB/T 14525-2010), which was implemented on October 1, 2011.


(1) Current situation of Flexible metal hose china manufacturer


First, production costs have risen too fast, raw materials have generally risen, labor costs have risen too fast, the problem of labor shortage is very prominent, and wages of workers in the Yangtze River Delta and the Pearl River Delta coastal areas have generally risen. The above two "cost rises too fast" squeeze the profit margin of Flexible metal hose china manufacturer.


Second, the financing condition of Flexible metal hose china manufacturer is difficult. A large number of small and medium-sized flexible metal hose enterprises solve the pressing problem through private lending. The borrowing interest rate is high. In 2010, China's current financial system is difficult to solve the "bottleneck" problem of small flexible metal hose enterprises with few financing channels, small scale and high cost.


Third, most small and medium-sized Flexible metal hose china manufacturer are at the low end of the traditional industrial value chain, with weak technological innovation ability, extensive production and operation, low equipment level, shortage of professionals, lack of independent intellectual property rights and brands, mainly relying on "low cost, low price, low profit" to participate in the competition, which makes it difficult to digest the rising factors of operating costs in time and adapt to the transformation of development mode.


Flexible metal hose china manufacturer warns that oxidizing films form on the surface of metals when they react with oxygen in the atmosphere. The iron oxide formed on common carbon steel continues to be oxidized, which enlarges the corrosion and eventually forms holes. Carbon steel can be electroplated 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 protective layer is damaged, the steel below begins to rust.


The corrosion resistance of stainless steel hose depends on the content of chromium. When the content of chromium is 10.5%, the atmospheric corrosion resistance of steel increases significantly, but when the content of chromium is higher, although the corrosion resistance can still be improved, it is not obvious. The reason is that when chromium is used to alloying steel, 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 kind of oxide layer is very thin, through which the natural gloss of stainless steel surface can be seen, so that stainless steel has a unique surface. Moreover, if the surface is damaged, the exposed steel surface will repair itself with the atmospheric reaction, and the passive film will be re-formed, which will continue to play a protective role.


(2) Development Prospect of Flexible metal hose china manufacturer


Most of the flexible metal hoses sold globally are produced and exported from Flexible metal hose china manufacturer. China has become the main Flexible metal hose china manufacturer in the world. Although China's flexible metal hose industry is large in scale, many Flexible metal hose china manufacturer often lack core competitiveness due to weak technological innovation ability, too single market structure and weak brand influence.


The sales volume of Flexible metal hose china manufacturer is about 14.5 billion RMB, of which the proportion of threaded stainless steel hoses is less than 25%. It is not only far from the structure of hose products in the international market, but also cannot meet the growing demand for stainless steel hoses in the domestic manufacturing industry.


In 2010, the unbalanced structure of flexible metal hoses is that the production of Flexible metal hose china manufacturer is not in line with the market demand. For example, users need a large gap in the optical fiber protection hose, but galvanized flexible metal hose is overproduction; modern manufacturing industry urgently needs a large gap in double-button stainless steel hose, but low-grade single-button stainless steel hose is overproduction.
