Officially recognized by Hobéon SKO as an ISO 9712 training and examination center
inspection-training.be is the online hub of KTN Inspection Training Center, supporting companies and professionals with training, certification preparation and knowledge development in inspection and Non-Destructive Testing (NDT). We deliver both open courses and tailor-made in-company programs, and we guide candidates toward (re)certification and (re)examinations in line with recognised standards such as ISO 9712. Our training calendar includes courses such as NDT Introduction, UT Level 1 & Level 2, MT Level 2, WDCD, and advanced modules like TOFD and Phased Array (PA), as well as options for re-exams and recertification. In addition, we provide NDT consultancy (procedures, quality and practical implementation) to support organisations on the shop floor.
MFL Array tank bottom solution
Magnetic flux leakage (MFL) detects anomalies in normal flux patterns created by discontinuities in ferrous material saturated by a magnetic field. This type of test can be used for piping and tubing inspection, tank floor inspection and other applications.
Tank Integrity Inspections
Flat bottom storage tanks can be found in on a broad range of locations. Varying from storage terminals to refineries to process industry. We offer services for owners, manufacturers and users. The assessments are supported by various NDT techniques, including floor scanning, UT, etc. KTN has these services available in house. Storage tank inspection according EEMUA or API standards includes inspection of the tank shell, floor and roof. NDT methods and techniques used for tank inspection include: ultrasonic testing, magnetic flux leakage, magnetic particle testing, dye penetrant testing and bubble leak/vacuum box testing. A tank floor scanner using the magnetic flux leakage technique is used for the initial scanning of the tank floor. Detected indications are verified using visual testing and ultrasonic thickness measurements. Bubble leak/vacuum box testing, supported by magnetic particle or dye penetrant testing, is used for testing the welds in both the tank floor and shell. The tank shell and roof, both external and internal, can be scanned using a remote access ultrasonic device. This has multiple benefits, of which the biggest is that there is no need for scaffolding. This makes the scanning process faster and decreases down time for the client. The information from all techniques is combined in the report to create a complete picture of the integrity of the tank.
Motorized scanner for Weld Inspection and Corrosion Mapping
The portable motorized scanner adds steering capabilities so that users can position it from a distance. This functionality is useful when inspecting large ferromagnetic surfaces, such as pressure vessels and tanks, where the area to be inspected is out of the operator’s reach. The scanner can be configured for corrosion mapping with a motorized raster arm or for weld inspection (both longitudinal and circumferential) with a probe holder rack.
FlexoFORM Flexible phased array probe
The Power of Flexibility! Pipe elbows are susceptible to damage, such as from flow-accelerated corrosion (FAC), but inspecting them is challenging since their shape changes from convex to concave, and there are many possible pipe diameters. The FlexoFORM™ solution integrates flexible phased array probe technology in a scanner to solve these challenges. This solution can be used to collect easy-to-interpret data on elbows with diameters ranging from 4.5 in. OD up to flat and offers many benefits, including: - 100% elbow coverage - Intuitive 2D C-scan imaging - High-resolution data (1 mm × 1 mm) - Fast elbow wall thickness measurement - Constant coupling maintained by water-column system
Weld Inspection
KTN has a wide range of scanners to address fabrication or maintenance weld inspections needs. We have solutions for small pipes up to flat plates with the capacity to hold multiple probes for complete weld volume coverage. Whether you choose a motorized or manual option, our scanners offer versatility, dependability, and repeatability.
Phased Array Weld Inspection

Whether you choose a motorized or manual option, our scanners offer versatility, dependability, and repeatability.
Corrosion Mapping
Ultrasonic corrosion mapping is a non-intrusive inspection technique that maps material thickness using ultrasonics. Variations in material thickness due to corrosion can be identified and graphically portrayed as an easy to interpret picture. KTN Belgium offers a complete solution with advanced phased array instruments, a range of automated and manual scanners, and a full range of probes and wedges!
Time-of-Flight-Diffraction (TOFD)
The Time-of-flight diffraction (TOFD) technique is an ultrasonic technique based on a pair of ultrasonic probes in a pitch-catch setup. One probe acts as transmitter and emits an ultrasonic pulse that is received by the second probe, the receiver. TOFD is one of the most reliable non-destructive testing methods in testing welds for both pre-service and in-service inspection. An accurate assessment of welds is vital to ensure that the stability and integrity of welded structures is not compromised by defects. Applications: Weld inspection (Pre-service and In-service) Inspection of intermediate welded welds Inspection at elevated temperatures varying from 50°C to over 250°C Detection of root corrosion Detection of cladding disbonding NII, Non-Intrusive Inspection Detection of Hydrogen Induced Cracking (HIC) and Stress Corrosion Cracking (SCC) Detection of High Temperature Hydrogen Attack (HTHA)
