ACFM
Alternating current field measurement (ACFM) is an electromagnetic technique used for the detection and sizing of surface breaking cracks in metallic components and welds.
It combines the advantages of the alternating current potential drop (ACPD) technique and Eddy Current Testing (ECT) in terms of defect sizing without calibration and ability to work without electrical contact respectively.
Eddy Current Tubes
Surface array challenges are something that companies face every day. When it comes to surface applications, the performance of any given inspection technique depends greatly on the specific conditions — mostly the types of materials and defects, but also surface conditions, cleanliness, etc.
In addition to our conventional ability to carry out Eddy Current through coated welds to determine surface-breaking defects, we also offer advanced Eddy Current Tube Inspection Techniques including Surface Array and Tube Inspection.
Phased Array
Corrosion under insulation (CUI), corrosion blistering and scabs, flow-accelerated corrosion (FAC), corrosion under fireproofing (CUF), and corrosion under coatings are possibly the greatest unresolved asset integrity problems in the industry.
Current methods used to measure wall thickness over lift off, without removing insulation, all have severe limitations and existing pulsed eddy current (PEC) solutions rely on outdated technology. It’s time for evolution – and phased array ultrasonic testing is that evolution.
Short Range Guided Wave
The use of Short-Range Guided Wave Ultrasonics makes it possible to inspect hidden areas of concern that are normally unreachable using conventional Ultrasonics or alternative methods of inspection.
Short Range Guided Wave Inspection utilises Bulk Wave Ultrasonics to effectively scan distances as far as 1 meter along components to screen for areas of material loss from corrosion and pitting.
TOFD
Time of Flight Diffraction, TOFD for short, can be used for a number of different applications, however it is primarily used for rapid weld testing of circumferential and axial weld seams or perpendicular TOFD scanning. SONOMATIC RAIS offers TOFD using the Olympus Omniscan inspection technology.
TOFD offers rapid weld inspection with excellent flaw detection and sizing capacities. The diffraction technique provides critical sizing capability with relative indifference to bevel angle or flaw orientation. TOFD can be utilized on its own or in conjunction with other NDT techniques.
Infrared (IR) Thermography
Detects temperature variations and has been widely used to detect breakdowns of thermal insulation of cryogenic storage vessels and thermal linings of furnaces etc. Areas of damaged and waterlogged insulation can be detected using this technique.
Thermography does not give a definitive indication of corrosion, but highlights areas where corrosion may develop in the future. The possibility of intermittent wetting and drying-out of insulation, especially on hot plant and pipework, leading to a misleading result needs to be kept in mind.
Pulsed Eddy Current
SONOMATIC RAIS offers Pulsed Eddy Current (PEC) using Eddyfi® Lyft™ inspection technology. The system allows measurements to be taken through any non-conductive materials such as insulation, protective coatings, concrete, and marine growth, without requiring any direct contact with the inspection surface.
State-of-the-art instrument; real-time C-scan imaging; fast data acquisition (up to 15 readings per second) with grid and dynamic scanning modes; and great flexibility thanks to extension cables, probe shoes, and an extension pole. Using the Lyft probes, Sonomatic can scan through thick metal and insulation.
