Corrosion Coupon Failures

Consequences Of Failure

We have observed an undeniable rise in corrosion activity over the past decade.  Partially due to more corrosion susceptible piping less effective corrosion control, as well as changing engineering practices, this trend demands a careful watch over piping corrosion conditions by any building owner or manager.

As we have well documented throughout this Internet site, corrosion coupons do not provide the level of accuracy necessary to monitor pipe corrosion conditions.  At best they offer some indication of improving or declining pipe water treatment efficiency; at worst they provide a false sense of security while the piping system deteriorates toward failure.  In some critical applications, such as fire sprinkler, they cannot even be used.

Nevertheless, corrosion coupons remain the primary tool used today in measuring pipe corrosion.
