Guided Wave Ultrasonic Testing (GWT)

It is electromagnetically generated and receives low-frequency ultrasonic guided waves. It is used for rapidly surveying a long length of pipeline from a single test location. The corrosion wall loss and cracks in aboveground, buried, and insulated pipes can be detected, and their locations and sizes can be estimated by analyzing the data with user-friendly software. it is a screening tool to verify the condition of a segment of a piping system or pipelines which takes longer times when using manual UT or visual inspection techniques and provides big cost saving from erecting scaffoldings and removing pipes insulations to conduct a visual inspection.
