Long Rage Ultrasonic Testing / Guided Waves Testing (LRUT/GWT)

Guided wave ultrasonic testing detects corrosion damage and other defects over long distances in
piping. A special tool (transducer ring) is clamped around the pipe and transmits guided waves in both
directions along the pipe. Reflected signals from defects and pipe features such as welds are received by
the transducer ring and sent to the main unit.

Applications

The main applications of this service are:

Inspect sleeved road crossings
Detect riser soil to air interface losses
Detect corrosion under insulation
Detect pipe rack support losses in-situ
Inspect buried or insulated lines
Difficult to access locations

Advantages

The main advantages of this service are:

Inspects difficult to access components without extensive excavation or insulation removal
Portable, battery powered equipment
Sophisticated software routines help identify and classify
pipe signals
Rigorous operator training and certification with individual
electronic keys which activate the system and track its use
by each operator
Embedded reporting software allows the operator to analyze
the results and produce a report on the spot

Equipment

Equipped with the following devices:

G4 mini 3 (designed for all pipe and tube applications)
GUL Solid rings 2” and 4”
GUL Compact rings (6”/ 8”/ 10”/ 12”/ 14”/ 16”/ 18”/ 20”/
24”) with 3 and 6 meters’ cables kit.
Wave reader (wavemaker) software for data interpretation
and reporting
