Five elements of selection of metal hose

1. The nominal diameter of the size hose, the choice of joint type (mainly flange connection, threaded connection, quick connection) and metal hose size, hose length.
2, the pressure according to the actual working pressure of the hose, then query the nominal diameter of the corrugated metal hose and the pressure gauge, decide whether to use a stainless steel tube type of metal hose.
3. The chemical properties of the medium conveyed in the medium hose are determined according to the corrosion resistance parameter table of the material of the hose.
4. The working temperature and range of the medium in the temperature hose; the ambient temperature when the hose works. At high temperature, according to the working pressure temperature correction coefficient of metal hose at high temperature, the pressure after temperature correction should be determined to determine the correct pressure level.
5. According to the state when the hose is used, the optimum length of the correct use and installation of the metal hose and the hose in the settlement compensation, the length calculation of various motion states of the hose, the minimum bending times and the minimum bending radius of the hose, and the correct selection of the length of the soft tube, and the correct installation of the tube.
