Non-Destructive Testing (NDT)

Non-destructive testing is a testing discipline that has been around for many years. Used mainly for the ability to test for corrosion and fatigue in products and assemblies. NDT can be used to inspect welds for cracks, plastic for flaws, components for fatigue and many other applications. With advances in technology of NDT, testing disciplines can be applied to most projects with reliable results.

Why do NDT?

This shows the fracture face of a sweep arm of an outlet device in a digester that had failed due to fatigue cracking. This crack went undetected for many inspections, until it finally failed causing costly downtime and equipment damage. We were called in after the failure to ensure the welding was in accordance to the procedures, in process NDT, and for final inspection using phased array UT Testing.

We provide testing, training and consultation in the following NDT disciplines:
Phased Array UT
Ultrasonic Testing (UT)
Eddy Current Testing (ET)
Magnetic Particle Testing (MT)
Penetrant Testing (PT)
Radiography Testing (RT)

All of our non-destructive testing is supervised by our ASNT Level III. Our testing technicians have the experience necessary to provide reliable inspection results.

We have worked on projects for pulp and paper, power generation, manufacturing, government agencies, and other assignments that make up our extensive inspection experience.
