Rubber expansion joint are the flexible insert elements.
Rubber expansion joints even having performance restrictions has advantages over another type of expansion joints:
-
Relatively small weight and therefore can be used without special setting equipment;
-
Because of expansion joints flexibility the product can return to a primary form after movement, deformation require less forces;
-
Natural and synthetic elastomers doesn’t fatigue, not become brittle and prevent any electrolytic action;
-
Reduce heat losses, while the п-type loops increase;
-
Rubber expansion joints are made from different types of elastomers, each of which are selected depending on service conditions and leaded medium, that made joints long-term and non-corrosive, non-erosive and abrasion-resistant;
-
Don’t require a sealing gasket;
-
There is much vibration and noise reducing in pipeline systems, because of expansion joint elastomer component act as vibration absorber;
-
This type of expansion joints has a good hydroblow resistance, which is made by cavitation in pump.
