The Basic Gauge Measurement Instruction course for Tubing and Casing is designed to
introduce, familiarize and teach correct gauging techniques for the proper measurement of
tubing and casing threads utilizing equipment commonly found in the industry. The course is a
full day, eight hour course comprising four sections with a break for lunch.

gauging techniques followed by “hands on” gauging of various threads in both passing and

graded to achieve passing completion of the course. Students are supplied with a Certificate of
