Thermal Fire Pipe Sleeve

Excellent Acoustic Insulation.

Suitable for use through a wide range of fire partition walls and floors.

Suitable for a wide range of plastic, copper and mild steel pipes.

Allows for thermal movement of pipe and maintains thermal insulation for the pipe through the penetration.

Description

Steel, copper and plastic pipes are found in all commercial and domestic buildings. A high percentage of these pipes will penetrate through fire rated constructions such as ceilings, floors and walls. Once a hole is made in a fire rated construction for the passage of pipes or services the integrity of the compartment is compromised.

To solve this problem ASTROFLAME have a developed ASTRO Thermal Fire Pipe Sleeve, which reinstates the fire rating of the construction and prevents fire spreading from one compartment to another, and prevents copper pipes from cement erosion.

The sleeve is a cost effective product for the fire stopping of pipe penetrations e.g. Plumbing pipe and metallic pipes whilst maintaining similar thermal and acoustic properties as standard mineral fibre insulation. These properties ensure compliance to water bye laws and building regulations for cold and hot water pipes and heating systems.

In a fire situation the sleeve expands to fill the available space between the pipe and the penetration. In the case of plastic pipes the sleeve will crush and close off the pipe forming a solid char and preventing the passage of fire and smoke to the adjacent compartment.

Tested on the following pipe sizes to BS 476 part 20 for 2 hours

Copper 12mm- 160mm
Mild steel 22mm - 160mm
Polybutylene 12mm - 28mm
PVC 55mm-160mm

All sleeves have been tested with a 25mm nominal wall thickness. Sleeves have been tested cut both flush to the wall / floor structure and leaving 25mm exposed for connection to standard pipe insulation

The sleeve is simple to install, easy to cut and one sleeve can replace two collars, the sleeve may also be fitted flush to the wall for a clean line solution.

Length 300mm. Wall thickness 27mm.
