Products Introduction
Usually, the Rubber expansion joints our CTA bellows designed is consisted by smooth rubber convolutions with flanch each side and loose metal flanges each side. The rubber part’s surface can be EPDM, NR, NBR, NEOPRENE etc and inner is multy-ply strong fabric or steel cord reinforced interlayer extended until flanch each side. The flanches each side is reinforced together with hard steel framework.
Performance feature of rubber expansion joints:Rubber expansion joint has good compensation ability which can meet axial, lateral and angular deflection. And it is also good at reducing noise, reducing vibration and corrosion resistance. So it is widely used because of its pressure resistance, good flexibility, large movement compensation and simple installation.
