Drainage Technology Fire protection coupling BSV 90 The easiest solution for cast iron pipe penetrations through fire-rated ceilings

BSV 90 – The First Fire Protection Coupling for Cast Iron Pipes Why fire protection for cast iron pipelines? The advantages of BSV 90 for cast iron drainage pipe systems Pipe penetrations through fire-rated ceilings have to prevent any fire spreading for at least the indi- cated duration of time in order to give the inhabit- Cast iron is a non-combustible material. pipe diameter and the gap around the pipe The ants sufficient time to escape. are closed in the event of fire, the future test re• No smoke formation quirements as per EN 1366-3 have been fulfilled Building practice has been...

BSV 90 – Operation and Technical Details A sealing rings on both sides. These sealing rings can be pushed onto cast iron pipelines. Around the PE collar and the sealing rings, there are several layers of intumescent material. intumescent material in several layers ceiling perforation≈ intumescent material A short collar made of PE is equipped with EPDM sealing ring The whole is contained by a stable metal casing. plastic collar An additional strip of intumescent material on the sealing ring outside of the metal casing guarantees that the steel casing ceiling penetration is completely closed...

BSV 90 – Child‘s Play Assembly and Flexible Installation Assembly Flexible installation Thanks to the intumescent strip fixed to the outside, The fire protection coupling BSV 90 must be inSML pipe stalled in vertical penetrations so that only the upper 40 mm protrude into the ceiling. This ensures that the intumescent material is sufficiently subject to heat in the event of fire, while the cast iron pipe a sound insulation of normal combustibility (class install coupling approx. 40 mm into the ceiling concrete, armoured concrete or cellular concrete 90 hardly impair the pipeline shape -...
