NDT Non-Destructive Testing
Advanced inspection techniques to evaluate integrity without causing damage or interrupting operations. Our certified professionals deliver comprehensive solutions for all your inspection needs.
What is NDT?
Non-Destructive Testing (NDT) refers to a range of inspection techniques used to evaluate the integrity of tanks, piping, and pressure vessels without causing damage or interrupting operations. Our experienced team applies these methods across all service areas.
It allows inspectors to detect flaws, cracks, corrosion, and other defects early ensuring assets remain safe, reliable, and compliant. NDT is essential for API 570 and API 653 inspections.
Key Scope of NDT
Comprehensive testing methods for thorough asset evaluation without damage
Ultrasonic Testing (UT)
Uses high-frequency sound waves to measure thickness and detect hidden flaws.
Commonly applied to tank bottoms, piping, and welds.
Magnetic Particle Testing (MT)
Detects surface and near-surface cracks in ferromagnetic materials.
Ideal for welds, tank shells, and piping systems.
Liquid Penetrant Testing (PT)
Applies dye penetrant to detect surface-breaking flaws.
Useful for non-porous metals and welds.
Visual Testing (VT)
The most basic yet critical inspection method.
Certified inspectors visually assess components for damage, leaks, or corrosion.
Advanced Ultrasonic Methods
Phased Array UT: Electronic beam steering for complex geometries and improved coverage.
PAUT provides detailed imaging and precise flaw characterization for critical welds.
Time-of-Flight Diffraction (TOFD)
Highly accurate technique measuring diffracted ultrasonic waves for precise flaw sizing.
Superior detection of planar defects and through-wall crack height measurements.
Why It Matters
NDT is essential for maintaining asset integrity while minimizing operational disruption
Non-Destructive Detection
Detects defects without halting operations or damaging equipment.
Early Risk Identification
Ensures early identification of risks before failure occurs.
Regulatory Compliance
Maintains regulatory and safety compliance standards.
Minimized Downtime
Minimizes downtime and repair costs through preventive detection.
Frequently Asked Questions
Common questions about NDT services
NDT can detect surface cracks, internal flaws, corrosion, weld defects, thickness variations, and material inconsistencies. Different NDT methods are suitable for different types of defects - for example, ultrasonic testing excels at finding internal flaws, while magnetic particle testing is ideal for surface cracks.
Inspection frequency depends on factors like operating conditions, material type, service environment, and regulatory requirements. Typically, critical components may require annual inspections, while others might be inspected every 2-5 years. Risk-based inspection (RBI) programs help determine optimal inspection intervals.
Yes, many NDT methods can be performed during operation without shutting down equipment. Visual testing, ultrasonic thickness measurements, and some radiographic techniques can often be done while systems are running, minimizing operational disruption and costs.
NDT inspectors should be certified according to industry standards like SNT-TC-1A, CP-189, or ISO 9712. Specific certifications depend on the method (UT, MT, PT, RT, VT) and level (Level I, II, or III). Many industries also require specialized certifications like ASNT or PCN.
NDT accuracy varies by method and application, but modern techniques are highly reliable. Ultrasonic testing can detect flaws as small as 1-2mm, while advanced techniques like phased array UT can provide detailed 3D imaging. Regular calibration and qualified personnel ensure consistent, accurate results.
