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

UFO sightings in New Mexico correlate with patents granted in the US. Popularity of the first name Alix correlates with carjackings in the US. Obviously, correlations can tell us a lot while also telling us nothing at all. In this episode of Pipeline Things, we dive into geohazards, geohazard statistics, and how the stories they tell aren’t always what they seem.

Tune in as Rhett Dotson and Christopher De Leon return with The Dirt Merchant to discuss why shark attacks appear to rise with ice cream consumption, and what Alex’s PPIM 2026 paper tells us about the prevalence of landslides and hydrotechnical events over time.

Highlights:

• The use and limitations of the PHMSA significant incident database.

• The impacts of data quality

• The key question: Are we getting better at managing geohazards?

• Is it too soon to tell if our geohazard programs are working?

• How consumer behavior affects industry patterns related to failures.

Canada may be just across the border, but when it comes to pipeline integrity management, the differences can make it feel like we’re oceans apart. Learn how each country balances the world of politics and regulators, the key differences in engineering approaches, and the distinction between performance versus prescriptive culture.

In this episode of Pipeline Things, Rhett and Chris bring on Dr. Nicki Robertson, who is currently standing up D2 Integrity’s Canadian office, to discuss pipeline regulations across borders.

Highlights:

• Key differences and similarities between each country’s regulatory environment
• How each country approaches interpreting regulations
• Relationships between operators and regulators
• Ensuring sound engineering for engineering assessments

On this episode of the Pipeline Things podcast, Rhett and Christopher sit down with guest Mark Ryan of Phillips 66 to discuss the impact of Part Three of the PHMSA Mega Rule on onshore gas gathering lines, 8-inch and up. The discussion confronts the reality that with its adoption, there are no longer any unregulated gas lines.

Highlights:

• Motivations behind the rule stem from a wide-scale effort to reduce emissions across the pipeline industry.
• Enhanced compliance thresholds for gas gathering lines have introduced challenges and opportunities for pipeline operators, like new classifications and reporting requirements.
• Implications of prescriptive vs. performance-based integrity management as the gas gathering space continues to evolve.

If you haven’t thought of the impact of the Mega Rule on gathering lines before, or if you’re knee deep in the new regulations, this episode is for you.

Excavating an anomaly flagged during an in-line inspection can sometimes feel like opening a box of chocolates. Say it with us, now: “You never know what you’re going to get.”

When determining whether a composite system is a suitable repair option, defining permanency (i.e., What does permanent mean to you?), evaluating the long-term strength of the system, and understanding the role of adhesion all come into play.

In this episode of Pipeline Things, Rhett and Chris sit down with special guest Tim Mally to discuss the ins and outs of using composites, common installation issues, and some of the major challenges with composite repairs.

Highlights:

• Essential variables considered when evaluating composite repair applicability

• The importance of surface prep and proper adhesion for a successful composite repair

• Exploring the heightened scrutiny of composite repairs compared to alternative methods

• Common questions with ensuring “permanency” of composite repairs
