Brief description of the selection elements of chemical hoses

    1, the actual working pressure of the chemical hose, the selected nominal pressure PN / working pressure
    2. Chemical hose nominal diameter, joint type and size. Hose length
    3. The chemical properties of the medium conveyed in the chemical hose, according to the corrosion resistance table, determine the material of each part of the hose

    4. The state of the chemical hose when it is used, refer to the correct installation method of the hose. The length calculation of the various movement states of the hose and the bending radius of the hose, etc., the parameters are correctly selected, and the length is correctly installed.

   5. Working temperature and range of medium in the chemical hose; ambient temperature when the hose is working. At high temperatures, the temperature correction factor must be used to determine the allowable pressure at the operating temperature to determine the correct pressure rating.
