RUBBER EXPANSION JOINT TYPE VS-1 FLAME-PROOF UNIVERSAL EXPANSION JOINT DN 40 – DN 150 STRUCTURE TYPE VS-1 / RUBBER BELLOWS PN 16 Universal expansion joint, consisting of a rubber bellows and rotating flanges Highly elastic molded bellows in various rubber grades Steel wire cord reinforcement Wire-reinforced self-sealing rubber rim Electrical impedance < 100 Ohm (DIN IEC 93, VDE 0303-30) Rubber grade* EPDM orange/blue Possible uses Hot water, acids, lyes Colour code hydrocarbon containing liquids *Check or inquire about the resistance of the rubber grade to temperature and medium. Technical design Max. perm. operating pressure up to +130 °C for brief periods* Bursting pressure Vacuum operation ≥ 0,05 bar abs. with vacuum supporting ring (from DN 65) Max. operating pressure to be set 30 % lower for shock loads. *> +110 °C the manufacturer's approval must be obtained for the corresponding operating conditions. FLANGES / VERSIONS APPLICATIONS for reducing thermal and mechanical tension in pipes and their system components, e.g. pumps compressors engines for muffling vibration and noise at appliances in cooling water and lub oil pipes for compensating axial, lateral and angular movement to compensate for installation inaccuracies to meet fire protection regulations shipbuilding industry in heating plants ACCESSORIES Others Corrosion protection 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 compensator. According to VDI Directive 2035, DIN 4809 part 1 and VGB R 455P, the manufacturer of the chemicals must state that the materials used in the compensator, especially for the rubber bellows, will not be damaged by the chemicals. Rotating flanges with stabilizing collar Flange drilling for through bolts Special turned groove for rubber rim Standard hot-dip galvanized, special varnish and coating, etc.
