The development process of the metal hose connector Release

Metal hose fittings in modern industry occupies an extremely important position. But the works of some kind of superheated high temperature medium; liquid hydrogen, liquid oxygen, liquid helium cryogenic medium class; gasoline, kerosene, acids, alkalis and other aggressive media ...... if using an ordinary connector to transport, that is certainly is not acceptable.After the development of metal joints for a long period of time to the late 17th century, the Dutch Golden Gai Wan • Bender brothers made ​​a longitudinal suture canvas hose, at the time of the fire service is widely used. Since the hose connector occupies an important position, the joints are also valued by the people since then. Later, with the rubber in the international market development, hoses and metal wire or twine and other fabrics armored hose come out. So, how is it developed it? Initially, people used animal skins Hydraulic pipe fittings Hydraulic pipe fittings sewn into a tubular structure to meet the needs of the struggle produced. Especially at high temperatures under the premise, it is more difficult to ensure the security and reliability.Therefore, it gradually to focus on the metal tube and metal hose connector, the changing geometry of the metal tube, to produce the corresponding corrugated external surface. In this way, both with the same flexibility with hose; same time, high temperature resistance, low temperature resistance, aging resistance, corrosion resistance. Thus, as the metal hose body metal bellows thus produced.
Corrugated metal hose from the tube as important in terms of the significance of the development of metal bellows, which means the development of metal joints. Subsequently, it is covered with the bellows outer bread rubber, nylon, plastic tubes or other materials, sheathed with metal wire or metal tape composed of nets, changing the form of a variety of connectors, to meet the variety of conditions different requirements to create various forms of metal hose. Metal hose fittings and metal hose in the course of history into mutual insurance, mutual development, and constantly adapt to the needs of society, but also to promote the progress of society.
