Rubber Expansion Joints

Temperature variations, setting in foundations, vibrations, forces and deformations cause noise, movement and/or stress in pipeline systems. Loggers’ rubber compensators neutralize the negative effects of these factors for pipeline systems that are exposed to chemicals and/or high pressures.

Our product portfolio consists of a wide program of high quality rubber expansion joints for various applications like (cooling) water pipelines and fuel pipelines. The ERV Series expansion joints carry multiple approvals by certification authorities as DNV, Lloyd’s register, Bureau Veritas and German Lloyds. These rubber compensators are available in various sizes, different neutral lengths and provided with flanges according to DIN or ASA.
