RUBBER EXPANSION JOINT TYPE AR-1 Please comply with the general technical instructions regarding reaction force, moving force, fixed point load, installation instructions etc. Subject to technical alterations and deviations resulting from the manufacturing process. UNIVERSAL EXPANSION JOINT DN 20 – DN 400 STRUCTURE TYPE AR-1 / RUBBER BELLOWS PN 25 Universal expansion joint, consisting of a rubber bellows and rotable flanges Highly elastic molded bellows in various rubber grades High-tensile synthetic fibre reinforcement Wire-reinforced self-sealing rubber rim Electrical impedance 103 to 106 Ohm (DIN IEC 93, VDE 0303-30) Rubber grade* Hot water, acids, lyes Possible uses EPDM orange/yellow Colour code hydrocarbon containing liquids *Check or inquire about the resistance of the rubber grade to temperature and medium. Technical design APPLICATIONS for reducing thermal and mechanical tension in pipes and their system components, e.g. pumps compressors for muffling vibration and noise at appliances n cooling water and lube oil i pipes for compensating axial, lateral and angular movement for compensating simultaneous movement in cooling water pipes to compensate for installation inaccuracies in sprinkler systems Max. perm. operating pressure Bursting pressure Vacuum operation DN 20 – 50 without vacuum supporting ring, DN 65 – 400 with vacuum supporting ring Max. operating pressure to be set 30 % lower for shock loads. *Please consider a decrease of pressure due to temperature (see technical annex). FLANGES / VERSIONS Rotable flanges with stabilizing collar Flange drilling for through bolts Special machined groove for rubber rim Standard ANSI, BS etc. Connection dimensions see technical annex page 213 – 215 Corrosion protection hot-dip galvanized, special varnish and coating, etc. Vacuum supporting ring Internal guide sleeve Flam
