Hands-On Experience with the Broadband Electromagnetic Tool in the Trench

Broadband electromagnetic (BEM) testing is being used as part of corrosion control/condition assessment practices on pipelines and force mains. The tool provides a means of measuring wall thickness of piping. Determining the level of internal and external corrosion is critical to evaluating assets' remaining useful life. The pros and cons of using BEM in the field will be discussed. The pipe materials include welded steel, ductile iron, and cast iron pipe. Case studies and lessons learned will be explained. In the trench testing techniques and limitations will be highlighted. The practice of using BEM testing in conjunction with or in lieu of ultrasonic testing will be evaluated.
