CorrView International, LLC, has announced its new tool for realistically monitoring corrosion activity in fire sprinkler systems. CorrView is a simple, low cost, and self-contained safety device in the form of a 3/4 in., 1 in., or 1-1/2 in. hex head pipe plug. Threaded directly into any fire protection system, it produces a brilliant color change, from white to fluorescent orange, after a pre-defined amount of wall loss has occurred. Its easily seen color change signals a hidden corrosion problem and corresponding rust deposit buildup. CorrView International, LLC.
