Request Pricing | ||
With unbeatable inspection capability and a truly simple user interface, the Maxwell PECT is an unmatched system in the field. A no nonsense, capable and flexible PEC inspection tool which has developed for harsh industrial environment inspections as well as applications in splash zones, subsea inspections and ROV deployments. The Maxwell PECT instrument is designed for the inspection of carbon steel and low-alloyed steels, which are magnetic. For magnetic test specimens, the eddy currents are concentrated on the surface directly after the magnetic pulse. Subsequently, the eddy currents diffuse into the test specimen, until the backwall is “found”. This results in a characteristic shape A-scan: a straight line, corresponding to the diffusion of the eddy currents, followed by curved section when the backwall is sensed. Weighing in at 7.5 kg (16.5lbs), including the batteries, the Maxwell system is highly portable; and with a typical battery life of 8 hours is an ideal inspection partner in the field.
Underwater Probe set covering different depth ratings & lift-off ranges
Probes S, M, L and XL with and without encoder attachments
Pulsed Eddy Current Testing (PECT) is an inspection technique for inspecting carbon steel objects such as pipes and vessels, without the need for contact with the steel surface. PECT can measure percentage variations in steel thickness through any non-conductive and non magnetic materials between sensor and surface such as air, insulation material, concrete, plastics, coatings, sea water and marine growth, paint, deposits, oil, composite repairs, fireproofing, “scabs” aluminum sheeting and other non-magnetic insulation covers; so ideal for Corrosion Under Insulation (CUI) applications. Previous instruments often lacked the power to be fast and effective.
Using the latest battery technology, the Maxwell PECT is a novel and very powerful PECT instrument with a design based on 25 years’ hands-on experience at a global Oil Company.
Applications include:
In-Service PEC Inspection of Storage Tank Annular Rings
Maxwell NDT has developed a flat PEC probe that can be inserted underneath the annular ring of a tank floor for in-service inspection. The Maxwell PECT is powerful enough to measure through thick layers of corrosion products (iron oxides) underneath the tank floor, which is essential for annular ring inspection. The removal of corrosion materials is clearly unacceptable for in-service inspection, as this may trigger a leakage, but with the Maxwell PECT system this removal process is not required.
