Non Destructive Testing

Our Non-Destructive Testing (NDT) processes such as guided wave, ultrasonic, acoustic emissions, vibration analyses, corrosion scanning, structured light, and traditional NDT methods identify defects, and gas, liquid, and energy loss. Corrosion under insulation (CUI) and other asset integrity defects are highlighted utilizing Guided Wave Ultrasonic Testing (GWUT) and Acoustic Emission Testing (AET). We also analyze for abnormal levels of ”blow-by” at vents and stacks downstream so we are gathering all the evidence to pinpoint every regulator, relief, or valve defect as well as assess any underlying latent risks. This involves utilizing other methods as well, i.e. ultrasound, infrared, radiography, tracer-gas, etc., in our surveys as best needed or as requested by our clients.

Guided Wave Ultrasonic Testing (GWUT) Overview

Condition based inspection programs have chosen to inspect their piping systems using Guided Wave UT (GUL) inspection to support mechanical integrity and preventive maintenance programs. Large sections of piping can be inspected rapidly and safely often with no scaffolding, and minimal insulation removal.
Leak Finder experts can locate and characterize defects internally and externally and will pick up cracking in many cases. The benefits of this program include increased efficiency of a plant’s inspection budget and minimizing maintenance upsets due to piping system failures. Multiple frequencies and wave forms characterize defects more accurately than ever before.
The GUL equipment can be used in many applications such as CUI, point of contact, road crossings, and air to soil transitions.

Leak Finder Advantages:
  • Excellent for Corrosion Under Insulation (CUI) inspections
  • Localized damage can be pinpointed and characterized as to length and depth
  • Excellent tool for cased crossings and unpiggable pipe
  • Point of contact corrosion can be found without lifting the pipe


Acoustic Emission Testing (AET) & Valve Surveys

From steam and water lines to natural gas and various other elements, Acoustic Emission Testing (AET) is a very valuable non-destructive testing (NDT) technique because it can "listen" for defects while systems are in operation.

From steam and water lines to natural gas and various other elements, Acoustic Emission Testing (AET) is a very valuable non-destructive testing (NDT) technique because it can “listen” for defects while systems are in operation. When valves aren’t functioning properly, not only can energy bills skyrocket, but imbalance within systems can cause operational capacity problems, increased risks, and premature component breakdown (wear and tear).

Our team has many years of success using AET for valve surveys to locate issues and waste with high speed and accuracy. Our teams and equipment have added flexibility to adapt quickly to system and connection variations on-site so getting readings upstream, downstream and at various key areas for analysis is done with ease, speed, and integrity.

Leak Finder makes it possible to optimize and execute effective and efficient NDE solutions that match-up to what will work best for its client's priorities as well as address the situational and indirect variables from all angles.
