- Strength & Composition -

Many industrial facilities generate corrosive exhaust fumes. These fumes often include high concentrations of sulfuric, hydrochloric, nitric and hydrofluoric acids, smoke, and high velocity solid particles. Various ductwork systems found in these facilities are designed to remove or filter some hazardous materials. Damage to a ductwork system due to fire will usually result in significant shutdown of a key process or an entire plant for an extended period, which can, of course, lead to substantial financial loss.


DUCTFLEX 32 is designed to extinguish a fire in duct and protect Fire Sprinkler System against possible seismic activity, vibration, movements resulted from pipe displacement independently.
