Inaccessible Area Inspection

A single sensor performs NDT pipe inspections circunferentially reflections up to 3m-10’ in front of the sensor. The technique is mainly used for detection of corrosion under supports (as a complement to the axial inspection technique), inspection of lamp posts, inspection of air-to-soil or air to cement interfaces or any area where the pipe or structure is not accessible.

Features

• Non-Contact EMAT technique.
• Circumferential scanning provides axial inspection of the pipes.
• Complements circumferential scanning during inaccessible pipe inspection.
• Different wave modes permit penetration under cement and any type of coating.
• Complements LRUT by providing accurate detection from 75mm (3”) to 3m (10’) in front of the sensor.
• Available for pipes up to 1” in thickness.
• Detects corrosion and pits as small as 1/10th of pipe thickness.

Instruments

• VOLTA
• Innerspec POWERBOX H
