Primary NDT Methods
The six fundamental non-destructive testing methods used across all industries.
Ultrasonic Testing uses high-frequency sound waves to detect internal flaws, measure material thickness, and characterize material properties.
Radiographic Testing uses X-rays or gamma rays to create images of a component's internal structure, revealing hidden defects.
Magnetic Particle Testing detects surface and near-surface defects in ferromagnetic materials using magnetic fields and iron particles.
Liquid Penetrant Testing reveals surface-breaking defects by applying a colored or fluorescent dye that seeps into cracks and discontinuities.
Eddy Current Testing uses electromagnetic induction to detect surface and near-surface flaws in conductive materials.
Visual Testing is the most fundamental NDT method, using direct or remote visual examination to detect surface discontinuities.
Advanced NDT Methods
Specialized techniques for complex inspection requirements and advanced imaging capabilities.
Phased Array UT uses multi-element transducers to electronically steer and focus ultrasonic beams for advanced imaging.
TOFD uses diffracted ultrasonic signals from flaw tips for precise defect sizing and is often paired with PAUT.
Guided Wave Testing can rapidly screen long lengths of pipe from a single probe position, ideal for insulated and buried pipelines.
Acoustic Emission Testing monitors structures in real-time by detecting stress waves emitted from growing defects.
Magnetic Flux Leakage uses strong magnets to detect wall loss and corrosion in pipelines and storage tank floors.
Corrosion Mapping provides detailed thickness maps of equipment walls to assess corrosion damage and predict remaining life.
Frequently Asked Questions About NDT Services
What are the main types of NDT testing methods?
The six primary NDT methods are Ultrasonic Testing (UT), Radiographic Testing (RT), Magnetic Particle Testing (MT), Liquid Penetrant Testing (PT), Eddy Current Testing (ET), and Visual Testing (VT). Advanced methods include PAUT, TOFD, and Guided Wave Testing.
How do I choose the right NDT method for my application?
The right NDT method depends on the material type, defect type you are looking for, geometry of the component, and applicable codes/standards. Use our free NDT Method Selector tool or consult with certified inspectors on NDT Connect.
How much does NDT testing cost?
NDT testing costs vary by method, location, and complexity. Ultrasonic testing typically ranges from $300-$1,500 per inspection, while radiographic testing can range from $500-$3,000. Get instant quotes from multiple providers on NDT Connect.
What certifications should an NDT inspector have?
NDT inspectors should hold certifications such as ASNT SNT-TC-1A or ACCP (USA), ISO 9712 (international), PCN (UK/Europe), or API certifications for specific equipment types. All NDT Connect providers are verified and certified.
Can I book NDT inspections online?
Yes, NDT Connect allows you to search for certified NDT providers, compare quotes, and book inspections online with real-time tracking for any NDT method worldwide.
