Rubber expansion Joints are flexible unions for pipes and rigid systems whose main purpose is no other tan protect equipment, avoiding rigid systems and pipe work rupture by thermal expansion and contraction, to absorb vibrations and noise generated by pressure pumping stations and also to assist with pipe alignment and being used as dismantling joints. They are consisting of synthetic rubber convolution fitted with metallic connectors at their ends, being flanges or threaded unions and are designed to perform axial movements and lateral and angular deflections.
