Rubber Expansion Joints can also be used to absorb contraction in cryogenic lines and reduce vibration in pipe systems. These joints could be made of stainless steel, rubber, or even a composite material. These joints are incredibly efficient, cost-effective, and safe to use. They are very much liked and widely used by people, in the market. Rubber expansion joints are flexible connectors made of natural and/or synthetic elastomers, fabric, and, if needed, internal steel reinforcements that provide stress relief in piping systems owing to heat and mechanical movements.
