Applications

Application areas of nondestructive testing

The systems of OKOSCAN-73HS family can be mounted on different chassis depending on end user`s requirements. A railway car or a hi-rail truck with truck bed will allow using large monitors and comfortable conditions for operators` work which is essential during continuous inspection of large railway track areas. Usage of hi-rail trucks is the most universal option because it allows to start and finish inspection at any rail/road crossing. This helps to plan inspection in the areas with busy train traffic.

The safety of movement on any railway track in the world depends on the quality of the railway track. The most cost effective solution is following the Risk Based Engineering principles which requires correct and up-to-date information about all rails in the railway tracks. Detection and further monitoring of the technical state of rails with operational defects allow their timely replacement. One of the main components of the rails defects detection approaches is ultrasonic rail inspection, which allows detection of both surface and inner defects in the whole rail cross section (except for the rail base wings).

Both the manufacture defects – the ones that appear in the process of production – and in-service defects of fatigue type may develop (fig.1) in various metal products. The cracks may develop at different angles to the surface growing to considerable depths thus causing the threat of a product breaking when in service.

Eddy current testing System of rails EDC RAIL 5065 allows to perform an automated eddy current testing for presence of the surface defects. Main defect types that are subject to testing by the System are the surface defects such as cracks, laps, hairline cracks located on the outer surface of the rail head and rail shoe of 49Е1, 60Е1, UIC60 rail types etc in accordance with EN 13674–1–2017 requirements.

Since early 2010, the OKOndt Group company has been conducting scientific-and-research and experimental-and-design works in the field of automation of the non-destructive testing methods for the railway wheelset elements testing. Implementation of the developed Systems for automated ultrasonic testing AUTS Axle-4 OS-4 and mechanized magnetic particle testing OS-38 (hereinafter – the Systems) enabled the enterprises of PJSC «INTERPIPE NTRP» and PJSC Lugcentrokuz a. S. Monyatovsky to promote their product at the world market and successfully certify their quality labs for compliance with requirements of European and American regulatory documents.
