Cathodic Protection Systems

Introduction

Corrosion is one of the major causes of ageing the industrial infrastructures. Maintaining the ageing infrastructure such as underground pipelines is a challenge to industries worldwide. Understanding why and how cathodic protection works or fails can help to formulate appropriate strategies in managing the pipeline corrosion problems. Understanding cathodic protection mechanism and how to control corrosion can lead to a remarkable improvement in the operation cost of piping and static equipment.

Proclad Academy’s Cathodic Protection Systems training course is designed to provide the participants with basic understanding of the technology related to cathodic protection, and best practices in designing, operating and maintaining cathodic protection of underground pipelines. This training course also covers typical designs of cathodic protection system, cathodic protection materials, potential measurements, monitoring and maintenance.
