Non-Destructive Testing

Non-Destructive testing (NDT) by Applus+

Non-destructive testing (NDT) encompasses a range of testing and inspection techniques used across various industries to detect defects and assess the properties of structures or materials without causing damage. 
As NDT inspection does not alter the part or structure inspected, it is an extremely useful technique that can lead to cost and time savings when applied to asset management, pipeline integrity, and failure prevention while reducing operational time and costs.

At Applus+, we have over 80 years of experience in the field of non-destructive testing, dating back to the founding of the Dutch group Röntgen Technische Dienst (RTD) in 1937, which became Applus+ RTD following its acquisition in 2006.

NDT methods

Applus+ NDT technicians utilize a wide range of non-destructive methods and technologies, including both conventional and advanced NDT techniques, such as:

Common NDT methods Advanced NDT

 

Applications and key benefits

With technological advances, these techniques enable the detection of both internal and surface flaws, including 3D visualization, which helps optimize maintenance processes and ensure compliance. NDT advantages include:

  • Risk reduction: Accurate identification of defects without compromising integrity
  • Time and cost savings: Efficient inspections throughout the asset lifecycle
  • Regulatory compliance: Meets applicable quality and safety standards
  • Operational productivity: Prevents failures that impact business continuity

 

Summary of NDT techniques and benefits

Technique Application Main Benefit
Ultrasonic Testing (UT) Internal flaws, thickness measurement High accuracy, deep penetration
Magnetic Particle Inspection (MPI) Surface flaws in ferromagnetic materials Fast detection, cost-effective
Liquid Penetrant Testing (LPT) Cracks on non-porous surfaces High sensitivity, simple method
Radiographic Testing (RT) Welds, internal structures 2D/3D imaging, permanent records
Remote Visual Inspection (RVI) Hard-to-reach areas Real-time imaging
Eddy Current Testing (ECT) Surface flaws in conductive materials Quick results, no contact medium
