1 the cost of rising prices. Iron and steel as the main raw material of stainless steel metal hydraulic hose adapters production has entered the price open and transparent small profits era, rising steel prices will push the stainless steel metal hose production cost;
The brand is poor in China 2 stainless steel metal hose connector industry, international competitiveness is weak. As a result of industrial concentration is low, backward technology, low price competition can not be avoided, China stainless steel metal hose is such a huge market has no real sense of "famous brand on the international";
3 fierce competition constantly eliminated a small stainless steel metal hose enterprise.
4 R & D strength is weak, insufficient capital investment. The technology progress of our country still stays in the overseas in twentieth Century 80 time, although it is a large number of the introduction of advanced technology and production lines, but the basic support for the technology digestion and absorption of the lack of hardware and software.
5 practical technology brain drain. At present, although China has engaged in research work in some colleges and universities, a lot of ethical research, patent papers have a very high level, but combined with production practice is not close, the theory into the finished product ability is poor.
hydraulic tube fittings,hydraulic hose,hydraulic fittings is with a one-way valve, one is without a check valve. Application with check valve, check valve and the gas source is connected to the end, when you disconnect the check valve closes automatically when you turn on the activity side thimble-way valve is opened. Is the use of self-locking ball is embedded in the groove, while the locking balls from "tapered cylindrical ---" sleeves.
