Quest Integrity Technology

In-Line Inspection Tool- InVista™

InVista is a lightweight, hand-held ultrasonic in-line inspection tool (intelligent pig) capable of detecting pipeline wall loss and corrosion in unpiggable or difficult-to-inspect pipelines. The advantages of ultrasonic inspection over MFL are listed below. The pipeline geometry inspection data captured by the InVista tool is exceptionally powerful when combined with our LifeQuest™ Pipeline fitness-for-service capabilities, providing an integrated solution set for the pipeline industry.

We have successfully performed numerous unpiggable pipeline inspections on a global scale. These include wharf lines, offshore risers, sulfuric acid lines and pipelines with significant dents and other obstructions. Scroll down to access case studies for some of these projects.

Unpiggable Pipeline Intelligent Pig Capabilities

  • Provides 100% overlapping coverage of pipeline geometry and pipeline metal-loss features in a single pass
  • Inspects 3"-24" (76mm-609mm) diameter and dual diameter pipelines
  • Navigates back-to-back bends with >90° short radius turns
  • Navigates bore restrictions, step changes, reduced port valves
  • Accommodates limited or missing launcher/receiver facilities
  • Functions in low flow or limited flow conditions
  • Inspects non-standard and bulging pipe material
  • Identifies significant wall thickness changes and wall loss
  • Accommodates single entry/exit, line stoppage, plugged valves
  • Traverses bottom unbarred tees, wyes and mitre bends

Ultrasonic In-Line Inspection Tool Benefits

Ultrasonic inline inspection technology has numerous benefits over magnetic flux leakage (MFL) tools. Some of these benefits are listed below:

  • Lightweight, hand-held intelligent pig reduces safety and operational risk
  • Lower pressure differential requirements and bi-directional capability minimize line disruptions
  • Unique design reduces wear, impact and debris collection
  • Ultrasonic inline technology measurement delivers accurate, repeatable results
  • Linear ultrasonic sizing minimizes verification digs and improves excavation and repair confidence
  • Permanent line modifications not required
  • Efficient pipeline inspections minimize offline status
  • Onsite turnaround and rapid pipeline geometry inspection data analysis allows real-time operating decisions
  • Ultrasonic inline inspection technology does not permanently magnetize pipe like magnetic flux leakage tools, thereby eliminating demagnetization repairs
