Overcoming Inspection Challenges With EMAT Robotic ILI Tools

Many sections of piping were previously constructed or are operated in ways that do not allow the use of inline inspection (ILI) tools of a traditional design. For more than 10 years, Diakont has focused on the development and deployment of tooling to support the inspection of these pipeline sections that were previously considered “unpiggable.” The approach to inspecting these pipelines is through the use of tethered, robotic, crawler-type tools that use the non-contact electro-magnetic acoustic transducer (EMAT) method of ultrasonic inspection. Diakont tools employ an advanced form of multi-angle high-resolution EMAT UT, such that they are used as combination tools
