The worldwide rail industry is in high demand with both passenger and freight trains scheduled to busy timetables across the network. Busy schedules mean reduced opportunities to inspect and maintain railway track and train components. The challenge is for ultrasonic inspection to detect defects early enough to allow planned removal of lines and maintenance of trains to prevent speed restrictions and breakdowns, whilst complying with stringent safety standards.

Ultrasonics is the most extensively used NDT inspection method within the rail industry. Material testing for surface and internal defects can detect, locate, evaluate, and diagnose discontinuities. Wall Thickness Measurement or Corrosion Mapping provides remaining (residual) thickness measurement and evaluates the dimensions of the rail component or surface.

Advantages of Ultrasonic Inspection:

The worldwide rail industry is in high demand with both passenger and freight trains scheduled to busy

  • Safe and Economical method
  • Provides instant results
  • Can detect most defect types
  • Provides early warning for maintenance and repair resulting in less disruption to travellers
  • Improved safety and reduction of broken rails
  • Can generate instant reliable data providing useful information to predict and prevent unscheduled maintenance
  • Improves probability of detection (POD)
  • Facilitates defect management
  • Rail life prediction and risk modelling possible when combined with other databases and tools
  • Automated UT scanning solutions available

Phoenix ISL have been a verified supplier to the rail industry for over 30 years with a dedicated range of ultrasonic transducers and accessories and provide custom-design scanning solutions to inspect train components, such as train axles and wheel bearings.

Rail Industry Transducers and Accessories

Ultrasonic Rail Inspection – Ultrasonic inspection can be split into manual and train-borne testing which is carried out by an ultrasonic test unit (UTU). Early detection of rail defects is desired to facilitate cost-effective removal or provide enough warning to plan for a possession of track.

Train Axles – External Inspection

Train Axles External Inspection

ACFM Axle Scanner

The ACFM Axle scanner was manufactured by Phoenix ISL to enable axle inspections both on and off rail stock and can inspect surfaces without the need for paint removal. Alternating Current Field Measurement or ACFM is an electromagnetic inspection technique that introduces an alternating current into the surface of a component to detect surface-breaking or ‘fatigue’ cracks. The ease of deployment enables the ACFM scanner to be used in rail depots, on wheels removed from train bogies, to screen for defects in axles before they threaten the integrity of vehicles. A full axle inspection can be performed in just two minutes using the semi-automated system, which requires no prior inspection experience by train personnel.

Hollow Train Axles – Bore Inspection

Hollow Train Axles Bore Inspection

Axle Bore Scanner

For the inspection of hollow train axle, this solution is compact, portable, and easy to set-up so enables the inspection of train axles, in-situ, by a single operator. Available in manual or automated configurations, the scanner can inspect axle bores from Ø25mm to Ø110mm by changing the probe head to the appropriate diameter. Both the automated and manual versions can inspect bores of any length by attaching lances to give the required stroke length. The automated version has two motorised axes to permit axial and circumferential motion through the bore either by Helical, Helicoidal or Raster scan patterns.

Inspection of axles and wheel bearing housings

Axle Probe Positioning Tool

Axle and Wheel Bearing Housing

A manual scanner to accurately position and move a large custom phased array probe onto a wide range of axles and wheel bearing housings to provide an encoded 360° inspection of the surface.

The tool comprises of a universal mounting ring to provide axial movement to position the transducer as required and features axial guiding slides, switchable magnetic mounting feet and a spring-loaded probe holder.
