RUBBER EXPANSION JOINT TYPE RS-1 FLAME-PROOF UNIVERSAL EXPANSION JOINT DN 25 – DN 300 STRUCTURE TYPE RS-1 / RUBBER BELLOWS PN 16 Universal-expansion joint, consisting of a flat-convoluted rubber bellows and rotable flanges Flat-convoluted molded bellows in various rubber grades Steel wire cord reinforcement Wire-reinforced self-sealing rubber rim Electrical impendance < 100 Ohm (DIN IEC 93, VDE 0303-30) Rubber grade* Hot water, acids, lyes hydrocarbon containing liquids Colour code Possible uses *Check or inquire about the resistance of the rubber grade to temperature and medium. Technical design Max. perm. operating pressure Bursting pressure Vacuum operation DN 20 – 50 without vacuum supporting ring, DN 65 – 300 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, DN 25 with Drill holes 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. NOTE 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. Chemicals used for water treatment (particularly in heating systems and coolant systems) can corrode the materials of the rubber expansion joint. According to VDI Directive 2035, the manufacturer of the chemicals must state that the data indicating that the materials used in the expansion joint, especially for the rubber bellows, will not be damaged by the chemicals. APPLICATIONS for reducing thermal and mechanical tension in pipes and their system components, e.g. pumps compressors engines for muffling vibrations and noise at appliances n cooling water and lub oil pipes i for compensating axial, lateral and angular movement to compensate for installation inaccuracies to meet fire protection regulations shipbuilding industry in heating plants CERTIFICATES CE (PED 2014/68/EU) Bureau Veritas DNV GL® / DNV ® Lloyd’s Register of Shipping TÜV/DIN 4809 (DN 2
