UR18-D Pass the review of standard measurement technology

Client Background

Railway operators and inspection contractors require reliable, repeatable ultrasonic testing equipment for routine track maintenance Inspection teams must work within strict possession windows, especially on main lines and urban metro systems Historically, rail flaw detection has relied on manual walking inspections that are slow, subjective, and cannot detect internal defects like transverse cracks in the rail head Equipment must satisfy the standard measurement technology review of the Chinese Academy of Railway Sciences before it is accepted for use Operators need systems that can be deployed quickly, require minimal lifting equipment, and are supported by technical service and training

Project Challenge

Ensuring that ultrasonic rail flaw detection equipment meets national metrological standards for accuracy and repeatability Maintaining consistent detection performance across different rail profiles and track conditions Reducing the time required to deploy and remove inspection vehicles from the track without lifting gear Providing data that can be independently reviewed and verified after the inspection crew has left the site Meeting the technical requirements of railway bureaus and inspection authorities for certification and standardization

Our Solution

UR18-D dual-rail ultrasonic flaw detection vehicle passed the standard measurement technology review by the Chinese Academy of Railway Sciences The vehicle uses a 9-channel wheel probe with automatic position and angle control for consistent detection Patented disassembled platform allows two people to carry and assemble the vehicle on track within five minutes A-scan and B-scan data are recorded continuously and can be replayed and transferred for expert review The system is designed for operation at 15 km/h with endurance of not less than 60 km or 4 hours of continuous work

Final Result

UR18-D became the first enterprise in China to obtain certification for special railway measuring instruments in ultrasonic rail testing The vehicle is now accepted for use in inspection programs requiring metrological certification Inspection teams can deploy the vehicle quickly and operate within short possession windows Recorded data can be reviewed independently, reducing the risk of missed defects The system supports standardized inspection across different railway systems and regions

Customer Benefit

Certification ensures acceptance by railway authorities and inspection bureaus Quick on-track deployment with no lifting equipment needed reduces downtime Consistent detection performance across different rail profiles and track conditions Data can be replayed and reviewed after the inspection, enabling second-level analysis Modular design allows for easy transport and maintenance in remote or difficult-to-access locations
