Minimal Role of MIC in Fire Sprinkler Systems

While it is true that microbiologically influenced corrosion (MIC) can be a contributing factor to the overall corrosion picture, it is not the primary cause of internal corrosion in fire sprinkler systems. Unfortunately, many within the fire sprinkler industry have over-emphasized the role that MIC in fire sprinkler systems plays in causing corrosion while under-emphasizing the predominant role that oxygen […]

ECS Dry System Vents Will Not Depressurize Systems

Necessary Dry System Vent Features Dry system vents that are used to exhaust or purge the oxygen rich gas from dry and pre-action fire sprinkler systems in conjunction with nitrogen generators must perform several important functions: They must allow for gas to exhaust from the piping but prevent liquid water from leaking in the event of a […]

Higher Data Center Temperatures Increase Water Leaks

Data Center Operating TemperatureWhile increasing the overall operating temperature in a data center may provide cost savings from reduced energy usage for cooling, there may be unintended consequences on other infrastructure. Higher temperatures increase the rate of any chemical reaction, including corrosion rate, so an increase in operating temperature will accelerate corrosion in fire sprinkler piping. Simply […]

Stop Sprinkler System Ice Blocks

Ice Blocks in Dry and Preaction Sprinkler SystemsWhen fire sprinkler systems are required in freezers, dry and preaction sprinkler systems are used because system piping cannot be filled with water. Air compressors that provide supervisory air pressure in these sprinkler systems routinely introduce small amounts of condensate moisture with the air. If enough water accumulates […]

New White Paper – Acid Corrosion

Acid Corrosion Caused by Chemical Breakdown of AntifreezeClick here to download the full white paper.Acid corrosion in antifreeze systems is due to the breakdown of two primary chemicals found in antifreeze – propylene glycol and ethylene glycol. While propylene glycol is required by NFPA to be used in antifreeze and ethylene glycol is not, ethylene […]

The ECS WPNI Process

What is WPNI? Simply stated, WPNI (wet pipe nitrogen inerting) is a process that displaces oxygen, which causes corrosion, with nitrogen gas inside wet pipe fire sprinkler systems. Any trapped gas remaining in the system after WPNI is not corrosive. Learn more about the science behind corrosion in wet pipe systems here. What equipment is […]

Fill & Purge Breathing

All Nitrogen Is Not Created EqualSimply supplying a dry pipe fire sprinkler system with nitrogen gas will not control oxygen corrosion. A vent is required to remove oxygen so that the sprinkler system can be resupplied by supervisory nitrogen gas. Currently, there are two primary methods of venting oxygen from dry pipe fire sprinkler systems:Fixed […]

New White Paper – Weld Seam Corrosion

The most common point of failure on fire sprinkler piping is at weld seams and welded outlets. The high temperature experienced during the welding process changes the metal structure and creates a Heat Affected Zone (HAZ). Weld seam failure is commonly mistaken as a material defect in the pipe, but it is in fact a […]

Water Isn’t Your Problem – Remove the gas!

MYTH: Your leak is due to fire sprinkler water corrosion. The dissolved oxygen in sprinkler water contributes significantly to corrosion in wet pipe fire sprinkler systems.FACT: Sprinkler systems are filled with source water that contains 10 ppm of dissolved oxygen (that’s 0.001% of water volume). Almost all of the oxygen available for corrosion in sprinkler systems is […]

Chemical Corrosion Inhibitor Compatibility

Before using a biocide or chemical corrosion inhibitor in your fire sprinkler system consider the following:Is the sprinkler system equipped with a reduced pressure zone (RPZ) type backflow preventer and if not how much will it cost to upgrade to prevent contamination of potable water with potentially toxic chemical corrosion inhibitors?How can an even distribution of […]
