Long Range Ultrasonic Testing - LRUT

Advanced NDT
Long range Ultrasonic (LRUT) 

LRUT method using multiple low frequency ultrasonic waves to detect the defects, the application of this method mainly to detect corrosion and damage of the pipe and pipeline metal However, LRUT can also apply to other devices in chemical factories, heat exchange, Oil Tanks etc. LRUT techniques using to test the pipe with diameter 1.5inch to 48 inch, pipeline can check up to 150m
