Galvanic Corrosion in Fire Protection Systems

Fire Protection Sprinkler Systems in commercial structures can be susceptible to galvanic corrosion, threatening the integrity of the FPS and ultimately presenting the risk of failure to operate.

Galvanic corrosion occurs when two different metals are in contact and both metals are immersed in an electrolyte. Moisture and humidity in a Fire Protection Sprinkler System that occur due to the presence of Oxygen in the system can affect the electrolyte resistance and spur galvanic corrosion. Additionally, moisture in the system's piping can also attract bio-organisms, coating the metals in a wet and slimy layer that can affect the areas exposed. (see Galvanic Corrosion in Wikipedia)

One solution to preventing the development of galvanic corruption in an FPS is to introduce a steady supply of clean, dry, inert Nitrogen gas. Nitrogen helps to eliminate the presence of moisture-inducing Oxygen to preserve the system, keeping it dry, efficient, and fully functional.

Using a Nitrogen Generator is the optimal way to supply a steady stream of N2 gas to the FPS. A Nitrogen Generator produces high purity N2 on site, on-demand, and at low pressure. It is a safe, reliable, and cost effective solution for preventing galvanic corrosion.

The N2-Blast™ Corrosion Prevention System from South-Tek Systems is designed to inhibit problematic galvanic corrosion in Fire Protection Systems by supplying dry, low pressure, supervisory N2 - an inert, non-flammable gas. It presents no risk of running out of N2 gas or having to deal with dangerous high pressure N2 cylinders. The N2-Blast requires less maintenance and less operational costs than cylinders.

Preserving the integrity of a commercial Fire Protection System is of utmost importance and one way to ensure preservation is in using the N2-Blast Corrosion Inhibiting System.
