NDT technologies is a world-wide supplier of non-destructive testing and measuring inspection systems for railroad rails, complying with international standards on production lines at steel mills.
NDT Technologies is a supplier of custom built automated quality control systems for measuring and testing rails, wheels and axles by non-destructive methods.
Our equipment provides assurance that products have been manufactured to the applicable international standards and quality control specification.
Our equipment has been installed in a number of major steel mills, in Europe, North America and Asia. In close cooperation with railroads and transport departments we have developed a unique technology for in track testing and assessment of the rail running surface condition.
Since 1981 NDT’s expertise and experience is based on electromagnetic, eddy current, laser, optical and ultrasonic technologies.
NDT Technologies Inc.
NDT Technologies’ product range includes:
RM 100 rail master
Acoustic equipment for on-site manual verification of rail ends or questionable sections of rail tracks.
MP 700 rail weld test multi-probe
System for manual verification of rail weld integrity including gas, resistance or alumino – thermic processes. The probe used in conjunction with ultrasonic flaw detector locates weld flaws inclusive lack of fusion condition and assists to standardise the inspection process. The system is usually used by welding crews for on site assessment of weld integrity.
Rail cleaning station
Automated rail surface cleaning and removal of loose scale prior to rail testing and measuring operations. Proper preparation of rail surface optimizes automated inspection process, assures repeatability of measurements and increases product integrity level. This equipment is used in steel mills.
Automated opto-laser measuring system of rail straightness, waviness, twist and dimensions. A fully computerized system using custom developed software provides rail measurement in full length during manufacturing process. Comprehensive reports indicating out of tolerance conditions are generated in graphic format. Measurement is carried out according to AAR rules and other specified standards. (Hot side measurement is also available).
Automated testing system for verification and surface flaw detection of manufactured rails in steel mills. Rail running surface, both sides of head, base and web is verified for the presence of dangerous surface anomalies such as cracks, seams or fractures. Rail surface integrity based on electronic signatures is digitally analysed, replacing relatively slow and labour intensive visual inspection. Rail production yield is optimized by a qualitative measurement directly based on reference calibration standards. The system is also superior to fluorescent magnetic examination by filtering out false indications such as surface scratches.
Automated system for detection of rail volumetric examination and internal flaws detection. Computer driven multi- channel ultrasonic test system provides full volumetric assessment of material integrity. The inspection process is based on electronic comparison measurements in relation to a set of artificial calibration standards. Rail head, web and base are examined on the steel mill production line. Adaptable and expandable design of the system also allows for testing of asymmetrical products. Our robust and reliable systems have been in operation since 1986.
