Over the past 16 years, CorrView International has investigated thousands of corrosion induced piping failures at HVAC and fire protection systems using ultrasound. For most clients, their first indication of a corrosion problem is a leak, major failure, or high volume of iron oxide rust deposits. All too often, years of very favorable corrosion coupon results are proven wrong, but only after significant and irreversable pipe damage has already occurred. Thought widely used, corrosion coupons have significant limitations to their accuracy for the following reasons: Isolation From the Main Circulating Loop Minimizes Most Corrosion Influences Difference in Water Flow Alters Corrosion Rate Activity Electrically Isolated From the Pipe - Major Component of Corrosion is Eliminated Short Testing Intervals - Excludes Long Term Impact of Corrosion Against The Pipe Effect of Surface Deposits Not Measured - Cannot Monitor Drained or Dead End Piping As a result of these common and well recognized problems, the CorrView corrosion monitor was invented. CorrView is a simple device which is threaded directly into any HVAC or fire piping system - in contrast to corrosion coupons, which are installed into a side stream loop, and therefore isolated from the pipe. The CorrView monitor has the same form factor as a standard hex shaped pipe plug. Its easy to install, self-contained, and requires...
