At Cutech, we deliver advanced NDT solutions to meet the unique demands of high-risk and heavily regulated environments. Our advanced inspection services support safe operations, reduce risk, and help extend asset life. We regularly carry out advanced NDT across oil and gas, marine, power, and infrastructure projects.
What is Advanced NDT?
The Evolution from Conventional to Advanced NDT Techniques
Advanced NDT techniques take basic flaw detection further by providing richer data, greater accuracy and improved reliability.
Conventional NDT methods (i.e. manual UT or MPI) rely heavily on operator interpretation and surface-level defects. Advanced techniques use digital tools, phased arrays, sensors and automation to:
- Detect flaws deep within complex geometrics
- Map corrosion or thickness loss over large surface areas
- Produce permanent digital records for traceability
- Enable real-time data visuals and remove assessment
Why Choose Advanced Inspection Services for Critical Assets
Advanced inspection services are essential where even minor defects could lead to failure.
At Cutech, we offer solutions tailored to asset type, project phase, and risk category. We monitor weld quality, pipework corrosion, and fatigue cracks in pressure vessels, for example.
Our Core Advanced NDT Services
Advanced Ultrasonic Testing (AUT)
AUT uses automated probes and scanners to deliver consistent and detailed inspection data across welds, pipe walls, and structural components.
Phased Array Ultrasonic Testing (PAUT)
Phased Array Ultrasonic Testing (PAUT) offers multi-angle scans of welds and components. This is ideal for thick sections, curved surfaces and time-sensitive inspections.
Time-of-Flight Diffraction (TOFD)
TOFD uses sound wave timing to measure crack depth and growth. This is particularly effective in pressure vessel inspection and long seam welds.
Acoustic Emission Testing for Structural Integrity
Acoustic Emission Testing detects active flaws as they occur. This makes it ideal for monitoring structural components under stress.
Vacuum Box Testing for Leak Detection
Vacuum box testing is a quick and effective way to detect leaks in weld seams and seams on tanks, vessels, and pipelines.
Holiday Testing for Coating Defects
Holiday testing detects pinholes or thin areas in protective coatings, supporting corrosion protection in offshore and subsea assets.
Vibration Analysis of Rotating Equipment
Vibration analysis helps to identify imbalances, misalignment or early bearing failure in motors, turbines and compressors.
Thermal and Infrared-Based Testing
We use infrared thermograph to assess electrical panels, insulation systems and rotating equipment for heat anomalies and internal defects.
Total Focusing Method (TFM)
The Total Focusing Method (TFM) is an advanced evolution of Phased Array Ultrasonic Testing (PAUT), offering full matrix capture (FMC) data acquisition and reconstruction. Unlike conventional PAUT, which relies on pre-set angles and beam steering, TFM digitally focuses at every pixel in the region of interest, producing superior image resolution and flaw characterization.
Magnetic Flux Leakage (MFL)
Magnetic Flux Leakage (MFL) is widely used for detecting corrosion and pitting on tank floors by measuring disturbances in a magnetized steel plate. The technique provides rapid scanning and high sensitivity to both surface and near-surface defects. It enables efficient mapping of large floor areas, helping prioritize repairs and extend tank service life. MFL can also be applied through coatings and linings, minimizing surface preparation requirements during inspection.

Visual and Remote Access Techniques
Drone Inspection and Aerial Drone Survey
At Cutech, we use drone inspection and aerial drone survey methods as part of our advanced NDT offering, for hard-to-access structures. This includes as flare stacks, chimneys and high-rise tanks.
Drone survey techniques allow for detailed visual data capture without scaffolding or rope access.
Remote Visual Inspection (RVI)
Our experienced inspectors also use Remote Visual Inspection (RVI) as one of our advanced NDT techniques. This inspection method is ideal for internal inspections in confined or difficult-to-reach areas such as pipework, vessels and ducting.
We use high-resolution cameras and snake-arm probes to provide real-time, accurate footage for reporting and compliance.
Piping Circuit Inspection (PCI)
At Cutech, we carry out Piping Circuit Inspection (PCI) to map corrosion loops, identify degradation zones, and assess risk areas in complex piping systems.
PCI supports long-term integrity management, particularly in refineries and chemical plants.
Pressure Vessel Inspection (PVI)
Our Pressure Vessel Inspection (PVI) services help to meet strict regulatory requirements and identify potential defects before failures can occur. This includes internal, external and NDT methods.
Piping Weld Inspection (PWI)
At Cutech, our Piping Weld Inspection (PWI) services cover PAUT, TOFD and manual testing methods to assess weld quality in high-pressure pipelines and critical joints.
We assist clients in detecting weld defects early to avoid failures, improve QA/QC outcomes and support compliance with strict industry standards.
Storage Tank Inspection
We apply advanced NDT techniques during storage tank inspection to assess floor corrosion, roof integrity, and weld condition using a combination of RVI, UT, and leak detection.
Our inspections combine remote visual inspection, ultrasonic testing, and leak detection methods to support safe operation and compliance.
Tube Inspection for Heat Exchangers and Boilers
Our advanced NDT tube inspection services use Eddy Current, IRIS and Remote Field Testing (RFT) to assess wall loss, pitting and internal blockages in boiler and heat exchanger tubes.
These advanced techniques provide detailed insight into tube condition, helping avoid failure and unplanned maintenance.

Advanced NDT Services FAQs
What is NDT testing?
Non-destructive testing (NDT), or advanced NDT refers to methods used to examine material condition without damaging the part being tested.
What’s the difference between PAUT and TOFD?
PAUT provides detailed scans of welds using multiple beam angles. TOFD measures flaw depth with high accuracy, especially in thicker materials.
How often should pressure vessels undergo PWI or PCI?
Inspection frequency on pressure vessels depends on service conditions, risk-category and applicable standards. At Cutech, we recommend integrating inspections in RBI plans.
