Non-Destructive Testing

Non-Destructive Testing (NDT) is a branch of testing that provides great advantages to the science and technology industry sectors due to its ability to evaluate the properties of materials using techniques that do not cause damage. It is an important solution for industrial inspection, especially for welding inspection and corrosion monitoring.

NDT application in manufacturing & installation processes help ensure:

  • High levels of quality, while increasing the product safety and compliance
  • Low prices by reducing waste product, material and workforce preservation
  • Improvement of prestige and competitiveness in the market


NDT application in operational processes allow clients to:

  • Ensure the safety of operating systems
  • Reduce and save on maintenance costs
  • Reduce amount of  time spent on plant shutdowns for maintenance purposes


NDT Offer

At Apave we provide NDT services with 3 main techniques:

  • Conventional NDT Services
  • Specialist NDT Services (Advanced NDT)
  • Other Related Services


While conventional NDT methods are currently the main inspection methods for new construction projects, new manufacturing platforms and manufacturing phases, advanced NDT methods are very useful and effective during the operation phase especially for corrosion monitoring. In addition, related services increase efficiency and reduce costs for clients, as is the case with NDT using rope access which results in cost-savings realted to scaffolding materials.

NDT Services

Corrosion mapping

Corrosion mapping is a technique which uses ultrasound to detect and identify damage to materials by mapping their thickness, which is then visually displayed as a graphic image.

  • Automated Ultrasonic (AUT) Corrosion Mapping  - RMS
  • High speed remote access ultrasonic (UT) crawler
  • Scorpion Tank Crawler
  • Hydro-form - Phased Array Corrosion Mapping
  • Flexoform– Phased Array Corrosion Mapping for pipe elbows and small diameter piping
  • 3D Laser Scanning for corrosion and mechanical damage assessment
  • MFL - Tank floor corrosion Mapping (MFL)
  • Pulsed Eddy Current – PEC
  • Pulsed Eddy Current Array - PECA and PECA HR
  • EMAT -  Electro Magnetic Acoustic Transducers
  • AE – Acoustic Emission
  • Digital and Real time radiography


Weld inspection

Welds may be tested using a variety of NDT techniques, allowing you to determine the integrity of welds - an extremely common component in the industrial sector.

  • PAUT and TOFD manual and automated weld  inspection services
  • ACFM – Alternating Current field measurement
  • Eddy Current Array (ECA) Weld and Stress Corrosion Cracking Inspections
  • Close proximity Radiography: Apave can supply close proximity equipment such as SAFERAD or SCAR that allows a number of units to be operated simultaneously in a small area, providing very high production rates. Barrier sizes are greatly reduced and easily manageable.


Advanced Tube Inspection

Advanced tube inspections allow you to continuously monitor the state of all types of tubes to determine their integrity and identify corrosion or other damages inside the tube, without the need to open it.

  • Remote Field Technology (RFT)
  • Near Field Testing/Near Field Array (NFT/NFA)
  • Magnetic Flux Leakage (MFL)
  • Eddy Current Testing/Eddy Current Array (ECT/ECA)
  • Internal Rotary Inspection System (IRIS)
