11-18: Assessment Of Existing Galvanic Corrosion Protection Systems

This paper will examine the protocol to assess an existing galvanic corrosion protection system installed on the veil of a hyperbolic cooling tower. In addition it will discuss the need to have reference cells for ongoing monitoring of a galvanic jacketed system for the columns elements of a cooling tower. NDE and visual evaluation techniques will be described in detail. We will use a case study to exemplify our evaluation protocol.
