construction, shipbuilding and in solar and wind plant engineering. It is especially used to absorb expansion and vibration and to insulate sound.
Bellow designLow-corrugated rubber bellow with reinforcement and shaped sealing bead with core ring, self-sealing (no additional seals required). Suitable for accommodating swiveling flanges.
Approvals/ConformitySimilar to DIN 4809 / TÜV approved, drinking water, shipbuilding approval
FDA and EG 1935/2004 conform
Flange versionBoth sides with swiveling flange made of galvanized steel, with clearance holes, drilled according to DIN PN 10 (standard). Other materials and dimensions are possible.
Type 55 is a low-corrugated, highly elastic rubber expansion joint. Its low corrugation helps to achieve very low flow resistance. It reduces up to 70 % of the incoming energy. It is also characterised by very high movement absorption in all directions and its variety of rubber qualities, which means that a suitable rubber com-pound is available for almost every application (see material descriptions on the following pages). Type 55 is used in building technol-ogy, plant engineering, water and wastewater technology, engine
