Non-Destructive Testing

Ensuring the integrity of materials, components, and structures without causing damage is critical for maintaining safety, reliability, and operational continuity. Non-destructive testing (NDT) enables organizations to detect defects, assess condition, and validate performance while keeping assets in service.
Kiwa supports asset owners, manufacturers, and operators with independent non-destructive testing services—using advanced inspection technologies and expert analysis to identify risks early, ensure compliance, and support informed maintenance and operational decisions.

What we do

Kiwa helps organizations evaluate the condition and integrity of materials, components, and assets without altering or damaging them through a comprehensive range of NDT services, including: 

  • Ultrasonic testing (UT)
  • Radiographic testing (RT)
  • Magnetic particle inspection (MT) 
  • Liquid penetrant testing (PT)
  • Visual inspection (VT)
  • Eddy current and advanced inspection techniques 

These methods allow for the detection of surface and internal defects, discontinuities, and material inconsistencies without interrupting operations or compromising the usability of the asset. 

Our experts apply the most appropriate testing techniques based on material type, application, and risk profile, providing insights into: 

  • Structural integrity and material condition
  • Manufacturing quality and weld integrity
  • Degradation mechanisms such as corrosion or fatigue
  • Compliance with industry standards and specifications

Kiwa delivers both laboratory-based and on-site inspection services across all stages of the asset lifecycle—from fabrication and construction to in-service operation and maintenance. 

Why Non-Destructive Testing Matters

Undetected defects or material degradation can lead to serious safety incidents, operational failures, and costly downtime. Without effective inspection and monitoring, organizations face increased risks such as: 

  • Catastrophic equipment or structural failure
  • Safety hazards for personnel and the environment
  • Unplanned outages and production losses
  • Non-compliance with regulatory requirements
  • Increased maintenance and repair costs 

Non-destructive testing plays a critical role in preventive maintenance and quality assurance by enabling early detection of defects before they lead to failure. 

Because NDT does not damage the tested object, it allows for repeated inspections over time—supporting continuous monitoring and long-term asset management.
