Rubber expansion joints for general industrial use. This type of rubber expansion joints are used for elimination of thermal dilatation in pipelines. The largest range of applications they found in vibration damping applications, vibration and noise from pumps and other vibrating pipe aggregates.
Rubber expansion joints are flexible „bellows“ manufactured by vulcanization of rubber mixture together with reinforced textile, or steel yarns
For increase of pressure resistance of rubber expansion joints is inserted in middle wall of bellows a reinforcement from textile or steel yarns
Rubber expansion joints are with swivel – galvanized flanges, fixed flanges, or threaded fittings with BSPP threads.
Rubber expansion joints are manufactured in dimensions from DN20 to DN2400 mm
Thermal resistance of rubber expansion joints is from -25°C up to max. 130°C, depending on material of used rubber and inside reinforcement of expansion joint
Pressure resistance of rubber expansion joints in standard version is PN 6, 10 and 16 (nominal pressure is at temperature 20°C). Pressure resistance depends from type and dimesnion and max. working temperature of medium. At working pressure of medium higher than 50°C is necessary to correct pressure resistance of expansion joint. Size of correction depends from type of expansion joint and material of „bellows“
