Astral PipesDescription
LOWER INSTALLATION COST: Astral FIRE PRO™ offers lower installation costs than metal systems. No special rigging or heavy equipment is required. Rigid and inherently strong, Astral FIRE PRO uses standard metal pipe hangers and requires fewer hangers and supports than other thermoplastic pipes, further reducing material and labor costs. TEMPERATURE / PRESSURE RATING: Astral FIRE PRO pipe and fittings are rated for continuous service of 175 psi (1207 KPa) at 150°F (65°C). Astral FIRE PRO pipe and fittings are suitable for use in areas where ambient temperatures are up to 150°F (65°C). LOW FRICTION LOSS : With a Hazen-Williams friction coefficient of C=150, Astral FIRE PRO’s smooth interior surface offers lower friction loss than metal systems, enables to use smaller pipe diameters and save on material costs. HEAT OF COMBUSTION : Astral FIRE PRO CPVC has a significantly lower heat of combustion at 7,700 BTU’s/lb, compared to Douglas fir at 9,040 BTU’s/lb, and polypropylene at nearly 20,000 BTU’s/lb. Materials with a high heat of combustion perpetuate a combustible mixture which ignites creating more heat and the burning process becomes self-sustaining. SUPERIOR PERFORMANCE, DURABILITY AND SAFETY IGNITION RESISTANCE: CPVC has a flash ignition temperature of 900°F which is the lowest temperature at which sufficient combustible gas is evolved that can be ignited by a small external flame. Many other ordinary combustibles, such as wood, ignite at 500°F or less. Accordingly, systems cannot be the ignition source of a fire. BURNING RESISTANCE: CPVC will not sustain burning. It must be forced to burn due to its very high Limiting Oxygen Index (LOI) of 60. LOI is the percentage of oxygen needed in an atmosphere to support combustion. Since earth’s atmosphere is only 21% oxygen, CPVC will not burn unless a flame is constantly applied and stops burning when the ignition source is removed.
