Sprinkler pipe corrosion is a serious threat for organizations that rely on dry, pre-action, and wet sprinkler systems to protect their facilities. Internal corrosion, resulting in the formation of localized pinholes, leads to costly damage from leaks and catastrophic losses when compromised sprinkler systems are rendered inoperable during a fire.
At South-Tek Systems, we understand the science behind corrosion and have always been committed to ongoing testing, having provided the Fire Protection Industry with the first and longest running corrosion study of sprinkler piping exposed to both compressed air and nitrogen gas. And we not only advise on sprinkler pipe corrosion, but we manufacture the most efficient and cost effective engineered corrosion solutions on the market.
Traditionally, compressed air was utilized as the source for maintaining supervisory pressure within dry and pre-action sprinkler systems. But due to the constant presence of oxygen in the compressed air, any part of the sprinkler system containing residual water left behind from hydro-testing, flow testing, or condensate accumulation is vulnerable to electrochemical corrosion.
South-Tek Systems designs and manufactures the N2-Blast® – Corrosion Inhibiting System, which effectively arrests electrochemical, galvanic, and micro-biologically influenced corrosion (MIC) by introducing up to 99.9995% pure nitrogen gas into the dry or preaction sprinkler system. The N2-Blast® also prevents ice plugs by ensuring a -40oF to -70oF dew point within the sprinkler system. As high purity nitrogen gas enters the sprinkler piping, corrosive oxygen and moisture are displaced through the N2-Blast® – AutoPurge System®.
South-Tek Systems’ full suite of wet nitrogen generator sprinkler system solutions offers the right level of sprinkler pipe corrosion protection for any facility. The patent pending DeOx™ – Dual Vent O2-Release System™ provides baseline defense by helping to eliminate the corrosive air-water interface along the high points of the sprinkler pipe network. To further reduce the likelihood of electrochemical corrosion, we recommend combining the Dual Vent O2-Release System™ with the DeOx™ – N2-Inert System™. The N2-Inert System™ is designed to rapidly pre-fill any wet sprinkler system with ultra-pure nitrogen gas and effectively displace up to 99.5% of the oxygen from within the system. And for maximum corrosion protection, look no further than the Patented DeOx™ – Water Deoxygenation System™. After employing N2-Inert™ technology to target the trapped oxygen at the high points of the piping network, the Water Deoxygenation System™ then removes the dissolved oxygen and harmful bacteria from the fill water prior to it entering the wet sprinkler piping.
