Rubber Bellows Expansion Joints/compensators have a special advantage in interrupting or muffling noise transmission in pipeline at pumps or machines in addition to their function as elastic pipe connections. They compensate for movements in pipeline, at pumps, Engines, Turbines, Machines, Equipment and Tanks and can be used to compensate for mounting inaccuracy as extension pieces on fittings or as sealing elements where pipe systems pass through walls. Rubber Bellows are manufactured from natural / synthetic rubber like EPDM, Chloroprene, NBR, Butyl and Chlorobutyl on a strong carcass made of synthetic/cotton fabric with reinforcement of steel wire, steel ring etc. Rubber Bellows are also available in many types like single arch, multi arch, and reducer type, offset type, sleeve type etc, and also available in many sizes from 25mm NB up to 2500 mm NB.
