The metal hose is generally composed of three parts: a bellows, a mesh sleeve and a joint. The bellows is the body of the metal hose, which plays the role of flexibility; the mesh sleeve plays the role of strengthening and shielding; the joint acts as a connection
Here are some of the elements of metal hose selection
1. Liquid temperature, working temperature and range of the medium in the hose, working ambient temperature. At high temperatures, the operating pressure temperature correction factor at the high temperature of the metal hose shall be determined to determine the pressure after the temperature correction to determine the correct pressure rating.
2, the transmission medium, the chemical properties of the medium transported in the hose, according to the corrosion resistance of the hose material, determine the material of the hose and each part.
3, the state of the hose, according to the state of the hose when used, refer to the correct use of the metal hose and the installation method and the length of the hose in the settlement compensation. The length of the various movement states of the hose and the small bending of the hose Factors such as the number of times and the small bending radius, the parameters are correctly selected and the length of the hose is correctly installed.
4, the pressure range, according to the actual working pressure of the hose, then query the nominal diameter and pressure gauge of the corrugated metal hose.
5, the correct length size and nominal diameter, the choice of joint type (mainly flanged, threaded, quick joint connection) and metal hose size, hose length.
