This Protecta-tested configuration provides a practical solution where multiple small combustible pipes need to pass through the same opening:
- 3 × Ø32 mm PVC, PP or PE pipes
- Each pipe containing one Ø14 mm cable
- Two layers of Protecta FR Wrap fitted around the complete bundle
- Installed through a pattress-fit Protecta FR Board
Within this tested configuration, no separation is required between the pipes, and no additional annular gap is needed to accommodate a sealant.
The FR Pipe Wrap also provides a controlled depth of expanding material around the bundle, reducing the risk of inconsistent application depths that can occur with site-applied graphite sealants.
Key benefits include:
- Fire classification up to EI 90
- Individual pipe diameters up to Ø40 mm
- Pipe bundles up to Ø110 mm
- Quick and straightforward installation
- Supplied in 25m rolls for efficient use across multiple applications
- 25-year working life under normal conditions
Always confirm the latest Protecta technical documentation for the specific pipe material, service configuration, supporting construction and required fire classification.
