Installation Instruction Compact-Seal-Insert DDL Pipe-Seal Proceeding

  • Make sure the surface of the core bearing /casing-pipe / carrier pipe in the installation area is clean.
  • Check the carrier-pipe for centric adjustment. Even if the compact-seal is made out of high-quality materials, it does not allow however the function as support-bar of the carrier-pipe.
  • Make sure the compact-seal is installed from that building side (nut side!), which allows easy access after finishing the installation, i.e. of retightening in case of setting conditions.
  • Push the compact-seal completely into the annular space (the installation will be improved by moisten the elastomer parts and/or the inner and outer surfaces i.e. by using soap-water (NO LUBRICANTS).
  • Tighten all nuts in clockwise direction (not crosswise!) with the same number of turns at a time until the entire space is completely filled up with the rubber element and the pipe-seal fits against inner and outer surface.
  • Tighten the screws clockwise by using a torque-wrench with the recommended torque (see table).
  • Due to possible setting after approx. 2 hrs. check the torque (for a pressure-tight sealing after approx. 48 hrs.) if necessary adjust.
