Fire Suppression

NuFLow 7000

NuFlow 7000 epoxy is listed by the International Code Council Evaluation Service (ICC-ES PMG-1532) for lining existing fire sprinkler systems in all residential and commercial applications.

According to the National Fire Protection Association “water not reaching fire” and “insufficient water discharged” accounted for 30% of reported sprinkler operation failures and over 80% of ineffective sprinkler operations. Given that the most common fire suppression systems are made of black steel and copper in the U.S., the sprinklers are highly susceptible to galvanized corrosion, Microbiologically Influenced Corrosion (MIC), air pockets and leakage, all of which instigate these water-related fire sprinkler failures and ineffectiveness.

Nuflow 7000

Fire sprinklers that are at risk for leaks or blockages can be safely and quickly lined with NuFlow 7000 rather than incurring the expense and inconvenience associated with replacement.

A proven-safe epoxy is blown into the pipe with a proprietary technique that coats the pipe interior, a process that has been utilized for decades in potable water applications.

The NuFlow 7000 epoxy, listed as PMG-1532, is the only product recognized by ICC-ES for application on copper, black steel or galvanized sprinkler pipe from 1/2 inch to 12 inches in diameter. The ICC Fire Suppression listing process included testing samples and an assessment of NuFlow’s quality system to ensure compliance with leading plumbing and mechanical codes and standards. This includes applicable sections of the International Fire Code®, International Building Code®, Uniform Plumbing Code®, as well as compliance with ASTM F2831-2019, ASTM D4541-2017 and ANSI/AWWA C210-2015, among others.
