RUBBER EXPANSION JOINT TYPE B-1 HIGHLY FLEXIBLE UNIVERSAL EXPANSION JOINT DN 32 – DN 400 STRUCTURE TYPE B-1 / RUBBER BELLOWS PN 16 Universal expansion joint consisting of a rubber bellows and rotable flanges Very elastic molded bellows with specially deep convolution in various rubber grades Synthetic fibre reinforcement Wire-reinforced self-sealing rubber rim Electrical impedance 103 to 106 Ohm (DIN IEC 93, VDE 0303-30) Rubber grade* Colour code Hot water, acids, lyes hydrocarbon containing liquids Possible uses *Check or inquire about the resistance of the rubber grade to temperature and medium. **Only available in large lots. Technical design 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. APPLICATIONS for compensating large axial and lateral movements for reducing thermal and mechanical tension in pipes and their system components, e.g. pumps compressors for muffling vibration and noise at appliances for compensating simultaneous movement in cooling water pipes to compensate for installation inaccuracies power station technology chemical industry Max. perm. operating pressure Bursting pressure Vacuum operation DN 32 – 40 without vacuum supporting ring, DN 50 – 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).
