Ultrasonic Testing: The Primary NDT Method for Rail Integrity
In the railway industry, ultrasonic testing is the most common nondestructive technique used. Flaw detectors based on this method are used to inspect rail tracks for internal defects, including hidden flaws (not visible on the surface) that could lead to fractures. These detectors operate by pulsing high-frequency sound waves into the rail. When these waves encounter a defect, they reflect, absorbed, or scattered. By recording and analyzing these changes in the sound waves, the detector can identify the presence, type, size, and exact location of a defect.
Ultrasonic testing can detect almost all critical internal rail defects. This method is crucial for identifying defects early on, which helps prevent rail failures and ensures the safety of passengers and freight.
The OKOndt GROUP range of ultrasonic rail testing equipment includes:
- High-speed Systems for rail inspection cars and hi-rail vehicles. These testing machines allow NDT technicians to inspect the rails continuously, with minimal disruption to train traffic. Among these options, hi-rail vehicles are considered the most cost-effective solution for regular track inspections.
- Hand-pushed rail flaw detector trolleys for railway inspection. These detectors confirm the results of rail testing carried out by high-speed Systems and monitor short track sections. They offer an economical and convenient alternative to rail inspection cars when localized testing of regional lines and industrial tracks is required.
