Five elements of selection of metal hose

1, size hose nominal diameter, the choice of joint type (mainly flange connection, threaded connection, fast connector connection) and the size of metal hose, 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 media transported in the medium hose, determine the material of the hose parts according to the corrosion resistance parameter list of the hose material.
4. The working temperature and range of the medium in the temperature hose; the ambient temperature when the hose works. At high temperature, the temperature correction coefficient should be determined according to the working pressure and temperature of the metal hose, so as to determine the correct pressure after the temperature correction.
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.
