INTRODUCTION
Corrosion of underground structures (pipelines, well casings, etc.) is a process that occurs every
minute of every day. As such, continuous protection is required to effectively prevent damage that
could cost a company significantly in lost revenues, manpower, and equipment. The proper
selection, installation, and operation of a suitable corrosion prevention system can be crucial to
ensure that this costly damage does not occur. For well-coated structures, structures with small
surface areas, or where minimal Cathodic Protection is required, a “sacrificial” type corrosion
prevention system may be used. For poorly coated structures, structures with large surface
areas, or where a larger amount of Cathodic Protection is required, an “impressed current” type
corrosion prevention system is required. One key component of an impressed current corrosion
protection system is a Cathodic Protection rectifier. A rectifier is a device that is used to convert
“alternating current” (AC), as provided by the power utility, to “direct current” (DC), as is required
for Cathodic Protection. The rectifier should be selected based on the type of control required for
the specific application, the amount of Cathodic Protection required to provide effective
protection, and the reliability of operation in the subject environment. IRT Integrated Rectifier
Technologies, Inc. manufactures Cathodic Protection rectifiers that exceed industry standards for
superior corrosion prevention and, as such, an IRT rectifier unit is a smart investment for any
company.
