INTERMEDIATE

This course presents subjects to advance the training of persons who already have an understanding of corrosion basics, to help them understand fundamental cathodic protection, installation procedures, and techniques, as well as gain knowledge of how to initiate appropriate procedures in construction, operation, and maintenance of corrosion control systems. Practical classes such as criteria for cathodic protection, impressed current interference, and rectifier maintenance are offered.

Two sections of the Intermediate Course are offered, taught simultaneously in two different classrooms by instructors utilizing a professionally prepared lesson plan. Students are encouraged to take the complete Intermediate Course and return the following year for the Advanced Course.

Prerequisite: 3 to 4 years of corrosion experience and/or completion of the Basic Course.

Intermediate Sub-Chairman: Tom Conner

 

Class Descriptions

CORROSION CELLS IN ACTION

A demonstration of electrical correction reactions using transparent cells in an optical projector.


INSTALLATION OF GALVANIC ANODES

The course will provide an overview of galvanic corrosion and the concept of providing cathodic protection of underground pipelines through the use of galvanic anodes. The course will describe the different types of galvanic anodes that are available, their chemistry, properties, and advantages and disadvantages. We will also discuss typical methods of installing the anodes.


INSTALLATION OF IMPRESSED CURRENT CATHODIC PROTECTION SYSTEMS

Construction practices and typical installations of various types of impressed current anode beds.


CRITERIA FOR CATHODIC PROTECTION

The generally accepted criteria of cathodic protection and their common usage.


CORROSION CONTROL FOR PIPELINES

Various corrosion control measures necessary during the installation of pipelines.


STATIC/STRAY CURRENT INTERFERENCE TESTING

Fundamentals of predicting, identifying and mitigating static stray current interference.


TROUBLESHOOTING CATHODIC PROTECTION SYSTEMS

Techniques used for making electrical measurements to locate problem areas on cathodic protection systems and the use of electrical network constraints.


RECTIFIER MAINTENANCE

Basic parts, function and maintenance of rectifiers.


INTERMEDIATE VOLUNTARY TEST

For students interested in receiving a certificate of achievement to acknowledge their completion and passing of the Intermediate Course.
