reusable hose fitting bellows habit called wave tube in the Americas

Corrugated Tube or corrugated sac (Corrugated Box), commonly referred to as a metal capsule in Europe (Germany Metallbulgen, England Metal Bellows). This name comes from the old-fashioned manual operation of blast air bag, in our vulgar call it "Paper Tiger."Japanse bsp threaded pipe fittings It is a kind of horizontal corrugated thin cylindrical shell under axial tension or pressure, can elongate or shorten; If you give it a lateral force appthe project some steam, high temperature hot medium class; liquid hydrogen, liquid oxygen, liquid helium cryogenic medium class;hydraulic fittings manufacturers gasoline, kerosene, acid, alkali and other corrosive media ...... if the hose to transport, of course not. Especially under high temperature conditions, it's more difficult to ensure the safety and reliability. Therefore, it gradually to focus on the metal pipe, the changes in the geometry of the metallic tube, so that the respective inner and outer corrugated surface. Thus, both have the same flexibility with hose; meanwhile, also has a high temperature resistance, low temperature resistance, aging resistance, corrosion resistance. Thus, as the metal bellows metal hose body thus produced. Structural characteristics of the metal hose: metal hose generally consist bellows, nets and joints of three parts.lied bending moment, you can get the corresponding axial plane displacement.
