RS PPS
The Roxtec RS PPS back-to-back seal has been developed specifically to address the challenges of plastic pipes passing through pressurised and fire rated areas. The seal consists of two Roxtec seals that protect against water and gas leakage. An intumescent sealing strip in the middle expands when the plastic pipe burns through, and fills the empty space to stop any fire from passing through.
The Roxtec RS PPS F+WT Kit consist of two RS PPS seals and two intumescent sealing strips that should be installed in a back-to-back arrangement for use in watertight bulkhead divisions on passanger ships and SPS vessels where sustained water tightness after fire exposure is required, in accordance to SOLAS ch. II-1 Reg. 13.2.3 (2009 issue). The products should be used in combination with a 700 mm long sleeve.
