Trinity™ ILI Systems: Built for Pipeline Integrity Confidence

Pipeline operators are responsible for transporting critical resources safely and efficiently, and failure is not an option. Ensuring pipeline integrity requires more than a single layer of inspection — it demands a system built for confidence.

That’s why ENTEGRA^® developed the Trinity™ ILI System, an integrated Ultra-High Resolution (UHR) inspection solution designed to deliver deeper insight in a single run.

Trinity™ ILI Systems

Trinity™ is a fully integrated inspection system built on three core components:

Advanced sensor architecture: High-density UHR Magnetic Flux Leakage (MFL), Caliper, and Low-Field sensors operate at elevated sampling rates, capturing a significantly richer dataset in a single run.

Structured, collaborative data analysis: ENTEGRA’s data analysis team applies a rigorous, collaborative evaluation process to transform high-resolution data into accurate, actionable insights.

Risk-managed execution: Inspections are delivered through a controlled, risk-focused operational approach, ensuring reliable execution and timely reporting.

Together, these elements form a system that delivers more than the sum of its parts.

Engineered for Real-World Pipeline Challenges

Trinity™ systems are designed to perform in complex, real-world environments. The tools are compact, lightweight, and highly collapsible, making them easier to handle, transport, and maintain.

They are engineered to navigate challenging pipeline geometries, including 1.5D back-to-back bends, while supporting a full range of dual-diameter operations. Bi-directional, tethered UHR tools are also available for select applications, providing additional flexibility in difficult inspection scenarios.

Why Trinity? UHR MFL In-Depth

Magnetic Flux Leakage (MFL) detects metal loss by magnetizing the pipe wall and measuring disruptions in the magnetic field. The amplitude and shape of these signals correlate directly to defect depth and morphology.

While this forms the foundation of MFL inspection, deeper insight comes from integrating multiple datasets collected in a single run, providing a more complete understanding of pipeline conditions.

Integrated Sensor Insights

Ultra-High Resolution Axial Magnetic Flux Leakage (AMFL): Enables high-resolution detection and sizing of complex metal loss features, including pinholes, clustered corrosion, and subtle anomalies.

Ultra-High Resolution Caliper (CAL): Measures dents, ovalities, and deformation, providing essential context for diagnosing mechanical damage and its interaction with corrosion.

Ultra-High Resolution Low-Field: Delivers material insights such as pipe grade, seam weld characteristics, and permeability variations—supporting more accurate root-cause analysis.

Inertial Measurement Unit (IMU): Available upon request, IMU data supports girth weld alignment assessment, geohazard identification, and strain analysis.

By combining these UHR datasets and drawing insights from the combined, layered results, Trinity™ enables operators to move from uncertainty to confident decision-making—all within a single inspection run.

Precision Matters in Pipeline Integrity

True UHR performance is demonstrated through improved Probability of Detection (POD), Probability of Identification (POI), and sizing accuracy. This level of precision allows operators to identify, characterize, and prioritize integrity threats with greater confidence.

Trinity™ ILI Systems consistently deliver high-quality inspection reports that enhance visibility of many types of key threats, all in one run, including:

• Pinholes
• Pits-in-pits
• Hard spots
• Mechanical damage
• Pipe grade variations
• Long seam features

Notably, Trinity™ enables advanced capabilities such as seam identification using AMFL—expanding what is possible with MFL-based inspection.

IMAGE CAPTION: Examples of features identified during the inspection: (1) Pinholes, (2) Pits-in-pits, (3) Hard spots, (4) Mechanical damage, (5) Pipe grade classification, and (6) Long seam identification.
