Wall sealing rubber compensators

The problems involved in achieving flexible sealing of lead-throughs for pipes, particularly large-sized pipes in industrial machinery through walls, ceilings, foundations etc. can be solved in a simple way using these rubber compensators. The specially designed compensators consist of a corrugated, pressure-proof rubber structure in pressure stages PN 1 and PN 2.5. They are made from non-ageing synthetic caoutchouc, either EPDM – resistant to hot water and acid – or buna N – resistant to oil – depending on the particular requirements, with a carcass of synthetic fibres and fitted with rubber flanges. The flanges are fastened by means of steel contact rings to the building structure on the side and to the pipe itself on the other side. Normally, wall sealing compensators are fitted during assembly of the pipeline in new buildings by sliding the closed rings over the pipe and flanging them in position. But it is also possible to fit divided compensators to closed pipes for retrofitting installation, when it is necessary to seal pipe leadthroughs or replace ex-isting sealing elements.
