LRUT- Teletest Focus+:

The Guided Wave long range ultrasonic testing is an advanced technology for detection and analyzing corrosion where access is difficult.

• Long range of inspection (30-50m) & 100% volumetric coverage.
• Detection of internal and external metal loss.
• Focusing capability to evaluate corrosion distribution around pipe circumference.
• Sensitivity can be as good as 3% loss of cross-section in ideal conditions (but is typically set at 9%).
• Ideal where conventional testing is impossible or very costly e.g. clamped, insulated, elevated, sleeved or buried pipes.
• Pipelines can be tested in service (no production shutdown).
• A wide range of pipe sizes (2” to 48”) can be inspected.
• Integral battery operation.
• Potential reduction of inspection cost due to the speed of the inspection.
