In a review of excavations triggered by EMAT results, about 80% of excavations revealed either a) no present anomaly features or b) anomalies unrelated to cracking. But we know the whole story is more complicated than that.

Not all EMAT technology works the same way, and this gap highlighted an opportunity for ILI vendors to step in and serve the market. Working hand in hand with an operator, NDT Global has developed a high-resolution inspection tool for gas systems that uses guided ultrasonic waves to detect crack features. Their PPIM 2026 paper, Development and Validation of a Novel Gas Crack Detection Tool Using Guided Waves, highlights the development and validation of the tool.

In this episode of Pipeline Things, Rhett and Christopher are joined by Michael Haas, Head of Sensor & Measurement Technology, and Rogelio Guajardo, Director, Product Management, of NDT Global, as they dive into the specific capabilities of this new technology, called CIGMA-x (also referred to as CIGMA).

Highlights:

• Exploring how EMAT shortcomings shaped this new technology development
• Discussing the 30-inch gas test loop, specially designed to test CIGMA-x capabilities with simulated features
• Breaking down primary tool capabilities and major findings from full-scale testing

How long should a permanent repair last? 50 years? Until the next scheduled maintenance?

According to RSPA 98-4733, “permanent” means as long as the pipe will be in service under normal operating and maintenance conditions.

In this episode of Pipeline Things, Rhett and Chris sit down with returning special guest Tim Mally to break down the concept of repair permanency, what it means from a code perspective, and what factors can influence the permanency of composite repairs.

Highlights:

• Breaking down what the code says about repair “permanence”
• What factors affect composite repair permanency
• Criteria to consider for composite reinforcement of non-standard features
• Evaluating existing composite repairs for permanency

There’s a lot to learn about difficult-to-inspect ILI tools, and who better to learn it from than the one and only Rienk de Vries from Intero.

In this episode of Pipeline Things, Rhett and Chris sit down with returning special guest Rienk de Vries, as they explore the wild west of difficult-to-inspect in-line inspection technology. It’s a conversation filled with details of Intero’s capabilities and advancements in recent years, how they’ve been changed, and where future opportunities might lie.

Highlights:

• Recent developments in Intero’s modular robotic MFL fleet
• What does the development cycle for these kinds of tools look like?
• What will it take to get a turbocharger?
• What is in store for future developments?
