BASIC

An introductory course in the fundamentals of corrosion and pipeline corrosion control, to help persons with 1 to 2 years of corrosion experience understand the basic fundamentals of electricity, galvanic and stray current, corrosion control methods, and field testing procedures. The course is designed to provide students with a technical foundation on which to build their corrosion expertise.

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

Prerequisite: 1 to 2 years of corrosion experience and/or completion of the Fundamentals Course.

Basic Sub-Chairman: : Geoff Rhodes


Class Descriptions

BASIC ELECTRICITY

A basic discussion of the types of electricity encountered in corrosion control work


CORROSION FUNDAMENTALS

A discussion and demonstration of how corrosion works, as well as the various forms of galvanic corrosion and how they apply to the corrosion of underground structures.


CORROSION CONTROL METHODS


INTRODUCTION TO PIPELINE COATINGS


POTENTIAL MEASUREMENTS

An introduction to the basic components needed to obtain potential measurements, with an emphasis on care and proper procedures. Instrumentation, instrumentation requirements, reference electrodes, potential measurements, potential measurement techniques, polarization effects, criteria for cathodic protection and monitoring of cathodic protection systems are also discussed.


RESISTANCE MEASUREMENTS

Topics covered: measurement of simple, isolated resistances (e.g. resistors, shunts, and bonds); non-isolated resistances (e.g. pip-to-casing, insulated joints, anodes or groundbed-to-earth, and pipeline-to-earth); and soil resistivity.


CURRENT FLOW MEASUREMENTS

Topics covered: measurements required to determine the current flowing on pipelines or piping in industrial applications or on other long metallic structures when an ammeter cannot be inserted into the circuit in the conventional manner; the application of these techniques to pipeline currents surveys and the use of zero-resistance ammeters.


WORKSHOP


RECORD KEEPING

Topics covered: the importance of record keeping with an emphasis on the general characteristics of records; various types of records and reports and their relative importance to government regulating agencies; and the advantages and uses of computerized records and manual field data records.


BASIC VOLUNTARY TEST

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