The existence of stainless steel metal hose industry problems

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 can not be used to replace ordinary dedicated connector

In the hydraulic system, either a metal hydraulic tube fittings, hoses or fittings, are prone to leakage problems. For card sets of pipe joints, mostly due to the pipeline by a larger force or impact, so that the card sleeve loose or pipe end surface deformation caused by leaks, you should check whether the card sets out of round, edge or without defects, whether the pipe ends in good condition and the extent of compression hydraulic tube fittings nut, but also eliminate the pipeline force. For flared tube hydraulic tube fittings, mostly due to excessive flaring, substandard quality requirements or repeatedly demolished, resulting in flaring deformation or cracks caused by leaks, then you can be re-flared front amputated.Hydraulic tube fittings in the hydraulic system, the connecting member and the pressure tubing hydraulic tube fittings  tubing between. If you use a male and female cone top pressure seal, which is mostly due to the two cone leak damage, is available on the cone grinders for grinding. For use oil sheet, wool felt, soft steel board, combination gasket sealant joints or pipe leaks, no matter what the material is, you should first check the seals for damage, deformation, aging and rough through the large, etc. and then take the appropriate measures.Hydraulic tube fittings can not be used to replace ordinary dedicated connector, because the hydraulic are can withstand a lot of stress.
