Guidelines for the selection of telescopic welded bellows metal hoses:
1. Nominal diameter of the size hose, joint type and size, hose length.
2. The actual working pressure of the pressure hose, the nominal pressure selected PN working pressure P.
3. The chemical properties of the medium entered in the medium hose are determined by the corrosion resistance table to determine the material of each part of the hose.
4. Temperature The working temperature and range of the medium in the hose; the ambient temperature when the hose is working. High temperature It is necessary to correct the number according to the temperature to determine the maximum pressure allowed at the working temperature to determine the correct pressure level.
5. The state is based on the state of the hose when it is used, referring to the correct installation method of the hose and various movements of the hose The length calculation of the state and the small bending radius of the hose, etc., correctly select the hose length and install it correctly.
