When choosing piping material for a fire sprinkler installation project, ask yourself these questions:
- Is it fit for purpose?
- How difficult is it to install?
- Is it approved for use in my building?
- Is this material built to last?
- Is it sustainable?
In addition to this, an overlooked (if somewhat obvious) question would be, how does this material respond and perform in an actual fire?
BlazeMaster CPVC (chlorinated polyvinyl chloride) is the most specified non-metallic fire sprinkler material in the world. One of the main reasons for this is its behaviour in an actual fire scenario.
Let’s take a look at BlazeMaster CPVC's performance in an actual fire and how exposure to flames does not prevent your fire sprinkler from distributing water to the places that need it most.
What happens to CPVC pipes in a fire?
Unlike typical PVC pipes, BlazeMaster CPVC is made from a specifically engineered thermoplastic material, with exceptional heat, flame and smoke characteristics, as well as chemical resistance and corrosion resistance.
BlazeMaster CPVC does not support combustion.
CPVC piping systems are made of chlorinated polyvinyl chloride and are self-extinguishing, thanks to their highly chlorinated molecular structure. Think of it as a natural defence mechanism against the spreading of flames; instead of spreading combustion throughout the pipe, a thermal barrier forms with a charred appearance that does not sustain a flame.
CPVC has an extremely high flash ignition temperature.
BlazeMaster CPVC has a flash ignition temperature of 482°C (900°F). That is the lowest temperature at which sufficient combustible gases evolve and can be ignited by a small internal flame. Wood ignites at 260°C (500°F) or lower.
BlazeMaster CPVC has a superior limiting oxygen index to alternatives.
BlazeMaster CPVC has a Limiting Oxygen Index (LOI) of 60; the Earth's LOI is 21. CPVC requires three times more oxygen than we have in the Earth's atmosphere to burn.
BlazeMaster CPVC does not contribute to the spread of toxins in a fire.
In addition to these advantages, BlazeMaster CPVC and solvent cement does not generate toxic smoke during a fire, nor does it produce burning droplets, therefore it does not make any contribution to property damage during an activation.
