EIWAA provides 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.
