What is ultrasonic rail testing?
Pandrol’s ultrasonic rail testing uses high pitched waves to identify defects in the rail. A full track inspection service is available, which provides an exhaustive report of the location, characteristics and urgency of all defects.
What is Herzog rail testing?
Herzog offers rail testing solutions that help clients reduce the risks associated with track failures and potential derailments. Our three vehicle platforms, fitted with multi-channel ultrasonic testing hardware, can efficiently traverse different classes of track and maintain quality service.
What is the range of ultrasonic testing?
400 kHz to 25 MHz
Most ultrasonic testing is available within 400 kHz to 25 MHz. These vibrations are beyond the audible range and propagate in the test material as waves of particle vibrations. Sound beams of all frequencies can penetrate fine-grained material without difficulty.
Why ultrasonic testing is important?
Accuracy and Sensitivity. Ultrasonic testing that applies advanced techniques and proven software algorithms can determine the size, shape, and position of most flaws in the right materials with better persistent accuracy than other NDT methods. UT is also sensitive to surface flaws, as well as those which lurk below.
Who owns Herzog?
William E. Herzog Enterprises
William E. Herzog Enterprises owns and manages all Herzog companies and their subsidiaries.
What does Herzog haul?
We deliver industry leading railroad services for all Class I and Shortline railroads in addition to commuter rail, light rail transit, and streetcar agencies across North America.
What is the maximum thickness for ultrasonic testing?
Conventional ultrasonic testing (according to BS EN ISO 17640) (1) limits thicknesses that can be examined to less than 8mm. Similarly, the draft phased array standard BS EN 13588 (2) goes down to 6mm.
How accurate is ultrasonic testing?
Under optimum conditions, commercial ultrasonic gages can achieve a level of accuracy as high as ±0.001 mm (0.00004 in.) and ±0.025 mm (0.001 in.) or higher in most common engineering materials.
