How does the introduction of nitrogen into a dry pipe sprinkler system affect corrosion rates and system longevity?

The introduction of nitrogen into a dry pipe sprinkler system significantly reduces corrosion rates and increases system longevity compared to using compressed air. Corrosion in dry pipe sprinkler systems is primarily caused by the presence of oxygen and moisture within the piping. When compressed air is used, it contains approximately 21% oxygen, which reacts with the metal pipe walls, leading to oxidation and rust formation. Rust accumulation can obstruct sprinkler heads and reduce water f....
