BonPEC

Key advantages

• Pulsed eddy current testing (PECT).
• Two probes as standard within the kit.
• Runs on an 11.6-inch rugged tablet (hot-swap battery, about 10 hours) or a laptop.
• Lightweight, adaptable system.
• Software leads you step by step through each survey.
• Creates reports automatically, with graphs and 3D results shown on a model or photo of the part.
• Non-intrusive inspection – no direct surface contact, cleaning or removal of sheeting.
• Measures through insulation, coatings, marine growth and concrete.

Overview

BonPEC is a non-intrusive electromagnetic technique that detects, measures and monitors corrosion in low alloy carbon steel pipes and vessels through insulation, coatings, paint, concrete fireproofing or marine growth. With no need for costly insulation removal or surface preparation, PECT is an efficient, cost effective solution for the on- and offshore industry and the energy sector – and works where the gap between the probe and the steel is too large for an ultrasonic thickness gauge.

Applications

• Corrosion Under Insulation (CUI) and Corrosion Under Fireproofing (CUF)
• In-service corrosion and wall thickness monitoring
• Splash zone inspection
• Inspection through repair wraps
• Flow Accelerated Corrosion (FAC)
• Remaining ligament assessment and well integrity

Operating range

Insulation	Up to 200mm
Sheeting	Aluminium or stainless steel
Temperature	-150°C to 500°C
Min. pipe diameter	50mm (2”)

Probes

Probe selection depends on lift-off and average wall thickness – the larger the lift-off, the larger the probe. P10 and P50 probes are supplied as standard. Thanks to magnetic field focusing, BonPEC probes are insensitive to nearby metal objects and, within limits, to lift-off change, angle mismatch and sheeting thickness, reducing false calls in the field.

Software

Built around the way an NDT survey is performed, the BonPEC software captures client and object parameters (pipe, plate or bend, nominal wall, lift-off, cladding) and guides probe selection and scan definition. It provides real-time interpretation on a touchscreen, advanced PEC signal analysis (footprint minimum wall thickness and more) and automatic reports with graphs and 3D projection of results onto an object model or photo.
