    Expansion Joints Feature

    10014oc0
    • Small volume, light in weight, very good flexibility, convenience installation and maintenance.
    • Transverse displacement, axial displacement, angular displacement.
    • Reduce noise, shock absorption.

    Expansion joints are specially engineered products inserted in a rigid piping system to achieve one or more of the following:

    • Absorb movement
    • Improved thermal stability
    • Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
    • Reduce mechanical noise
    • Compensate for misalignment
    • Eliminate electrolysis between dissimilar metals
