View Full Version : Pipe penetration for A60 fire rated wall

16-12-2015, 01:58 PM

I have come across a requirement where I need to penetrate an A60 fire wall for the refrigerant pipes. What is the standard way of doing this?

Can I use a pipe sleeve, and run both the refrigerant pipes in this, or should I have individual pipe sleeves for each refrigerant pipe?

The fire rating achieved will be limited to the fire rating of the building
element through which the service passes. The size of the gaps around
services that can be protected with Promat PROMASEAL® sealants have
limitations. For metal pipes passing through floors the gap between the
pipe and floor should be no greater than 38mm and for walls no greater
than 20mm. For bundles of cables passing through floors, the maximum
opening should be no greater than 50mm diameter (approximately
2000mm2) and through walls, 38mm diameter (approximately 1100mm2).

It would seem together is OK as long as the thickness of the seal is within limits.
