    Pipe Expander Maintenance
    Pipe Expanding Machine Maintenance

    By expanding the diameter of welded steel pipe, the pipe expanding machine is able to eliminate the internal stress, generated by forming and welding, of pipe wall materials, thus making the stress distribute uniformly and the straightness, roundness and diameter of steel pipe reach high precision.

    Maintenance Tips
    1. Clean the oil tank and filter the hydraulic oil once within one to two months after the machine comes into use. When cleaning the oil tank, do remember to clean the inlet filters of pumps.
    2. Check fasteners of each part and ensure they are fastened.
    3. If the pipe expanding machine fails to advance or withdraw, check if the solenoid valve functions normally and whether the sequence valve, overflow valve or unidirectional unloading valve is stuck. Remove the valve, clean it with gasoline or diesel, and reinstall.
    4. If the oil-resistant rubber seals in the joints of hydraulic pump station damage or leak, please replace them in time.

    Cangzhou Aocheng Machinery Equipment co., LTD. is a trusted pipe expanding machine manufacturer in China. If you are interested in our product, please do not hesitate to contact us.
