Quadra™ Multi-Axis UHR MFL ILI System

Comprehensive multi-technology inspection for complex-threat environments

Single-Run Insight. Maximum Integrity Confidence.

Built on the proven Trinity™ UHR ILI platform, the Quadra™ UHR ILI System combines Circumferential MFL, Axial MFL, Caliper, and Low-Field technologies to help operators detect, identify, and size complex interacting threats in a single inspection run.

By integrating Circumferential MFL, Axial MFL, Caliper, and Low-Field technologies, Quadra™ addresses critical gaps in seam-related threat assessment, narrow linear indication detection, and complex corrosion profiling. Quadra gives operators a deeper, more complete story of pipeline conditions - empowering confident, cost-effective decisions for higher-risk assets.

Comprehensive Integrity from All Angles

With the Quadra™ UHR ILI System, operators gain the most advanced MFL dataset in a single run. Four distinct Ultra-High Resolution sensor arrays work together to provide complementary inspection perspectives, ensuring critical features are detected, accurately identified, and precisely sized within the full context of pipeline integrity.

Building on the proven performance of Trinity™ UHR, Quadra™ expands Ultra-High Resolution inspection capabilities across four critical threat categories:

Metal Loss and Corrosion
  • Pinholes

  • Pits-in-pits

  • Complex corrosion

  • Narrow axial metal loss features

Seam and Axial-Oriented Threats
  • Narrow linear indications

  • Axial slotting

  • Seam-related anomalies

  • Metal loss interacting with the seam

Geometry and Mechanical Damage
  • Deformation

  • Mechanical damage

  • Gouges

Material Insight
  • Hard spots

  • Pipe grade classification

  • Manufacturing anomalies

  • Material variability

The result is high-confidence Probability of Detection (POD) and Probability of Identification (POI), providing clearer, more detailed, and highly repeatable inspection data. With greater confidence in every inspection, operators can make faster, more informed integrity decisions, reduce uncertainty, and optimize maintenance planning.

Key Features

  • Compact, collapsible mechanical configuration designed to support efficient deployment and handling.

  • Fully integrated Data Analysis team structured to maximize utilization of UHR data.

  • Optional Inertial Measurement Unit (IMU) reporting available for pipeline movement and geohazard assessment.

  • Engineered to navigate challenging pipeline geometries, including 1.5D back-to-back bends, subject to pipeline conditions.

Why Choose Quadra™?

  • Reduced risk and improved confidence: Improved probability of detection (POD), probability of identification (POI), and sizing accuracy across the most prevalent pipeline threats.

  • Lower cost and reduced downtime: One run replaces multiple inspection campaigns, reducing operational disruption and unnecessary excavations.

  • Better decisions: Richer contextual data to distinguish interacting features, prioritize remediation, and defend integrity decisions.

  • Unmatched operational reliability: Engineered as the shortest, lightest, and most collapsible configuration in its class, boasting an industry-leading >98% First-Run Success rate.
