SRUT – Short Range Ultrasonics
SRUT – Short Range Ultrasonics : Advanced NDT Solutions personnel provide Short Range Ultrasonic Testing (SRUT) which can be used for tank floor inspection vessel inspection for detection of corrosion CUI detection for piping or corrosion on under pipe support. Guided Wave is a technique which uses low frequency sound waves to flood thin wall material and then reflect back at interfaces such as cracking or corrosion/pitting. The guided wave technique is to be used as a screening tool only as remaining wall thickness measurements cannot be achieved. However, reflection distance can be measured with precise accuracy.
Advantages
- Limited access – insulated line with minimal insulation removal, corrosion under supports without need for lifting, inspection at elevated locations with minimal need for scaffolding, and inspection of road crossings and buried pipes
- Data is fully recorded
- Fully automated data collection protocols
