Description

In this course, you will learn the fundamentals of pipeline wall thickness measurement using ultrasonic thickness techniques—a critical skill in the oil, gas, and industrial pipeline sectors. We will begin with the fundamental principles of ultrasonic testing (UT), including how sound waves are utilized to assess the remaining wall thickness of metal pipes and components. The course covers relevant industry standards, including ASME and API, to help you understand compliance requirements and best practices.

You’ll learn from a few practical examples of performing accurate field measurements, including proper probe selection, angle, and positioning. Calibration procedures will be thoroughly explained and practiced to ensure reliable and repeatable results. Special focus will be given to techniques for various pipe materials and conditions, including those with corroded or coated surfaces.

Participants will also learn how to interpret data correctly and prepare professional onsite field reports for customers, clearly communicating results and recommendations. An essential part of the course is calculating corrosion rates from wall thickness readings, enabling predictive maintenance and safety evaluations.

This training is ideal for technicians, inspectors, engineers, and anyone involved in pipeline inspection, maintenance, or asset integrity. By the end, you’ll be confident in applying UT techniques to real-world scenarios with accuracy and professionalism.
