BSV 90

Product catalog summary

Introduction
The document introduces the BSV 90, a fire protection coupling designed for cast iron pipe penetrations through fire-rated ceilings. It highlights the need for fire protection in cast iron pipelines to prevent fire spread and ensure safety.

Why Fire Protection for Cast Iron Pipelines?
Cast iron drainage systems are known for their safety in fires, as they do not transmit fire or emit toxic gases. However, they do transmit heat, which poses a hazard. The BSV 90 addresses this by preventing heat transmission.

Advantages of BSV 90

No Fire Transmission: Cast iron is non-combustible.
No Smoke Formation: The materials do not emit gas, achieving a European fire classification of A1.
No Heat Transmission: Thermal insulation between pipe pieces.
No Chimney Effect: The pipe and surrounding gaps are sealed during a fire.
No Installation Problems: Installation is similar to normal couplings, requiring minimal space.

Technical Details and Operation
The BSV 90 uses a plastic collar and intumescent material to obstruct the pipe during a fire, preventing heat transmission and chimney effects. It consists of a PE collar with EPDM sealing rings and multiple layers of intumescent material, encased in a metal casing.

Fire Testing and Approval
The BSV 90 has been tested and approved according to EN 1366-3 standards, with a fire rating of 90 minutes (EI 90). It is suitable for vertical cast iron pipelines through concrete ceilings of at least 15 cm thickness.

Installation and Flexibility
The BSV 90 allows flexible installation with minimal impact on pipeline shape. It supports connections to plastic pipelines and requires only standard noise insulation. The coupling should be installed with 40 mm protruding into the ceiling.
