Elastomer Expansion Joints

Since their introduction in the early sixties, the use of non-metallic expansion joints has not stopped growing.

The advent of more and more stringent standards relating to the emission of gases had the effect of greatly increasing the complexity of ducting systems. The non-metallic joints are used on a more frequent basis, replacing traditional metallic joints. Elastomer joints can be used in systems where operating temperatures are lower than 400 F.

The industry, in adopting this type of joint, has taken advantage of the multitude of opportunities offered by the non-metallic joints when compared to other types.
The non-metallic expansion joints offer the possibility of absorbing multi-plane movements with a relatively short face to face dimension. They have the ability to absorb axial movement, lateral in the two planes, and angular twisting movement which can not be achieved using standard metallic joints.

The inherent characteristics of elastomers contribute highly to eliminate vibrations and noises thus preventing the premature deterioration of the system. The total number of joints can be greatly reduced in taking advantage of the absorption feature of large movements in all directions with only one joint. System geometry can be simplified. Utilization of structural supports and of expensive anchoring systems can be considerably reduced.
