    RMS PA Phased-Array inspection solution leads the way for a 100% corrosion mapping coverage of critical assets. The solution can inspect 10 times faster at a higher resolution compared to conventional UT.

    Phased-Array Corrosion Mapping

    Automated corrosion mapping has become an integral part of NDT inspection campaigns and is widely accepted within integrity management programmes and written schemes of examination. To optimise productivity with resolution, historically corrosion mapping systems have been set to 3-5 mm resolution steps.

    Incorporating Phased Array technology into an automated corrosion mapping system can help increase productivity, without sacrificing resolution and probability of detection.

    Phased Array probes have a wide electronic footprint and with a 1 mm resolution across the width of the beam, the required scanning coverage is achieved with significant time reduction. The ability to collect high resolution and increased scanning speeds, will improve probability of detection, enhance imaging and improve defect characterisation.

    The phased-array configuration utilises a specially designed water box which produces a controlled and stable water-column that eliminates the need for a wedge, thus providing the benefits of improved signal consistency, accuracy and limited dead zone. This concept offers enhanced surface conformance and improved coupling.

    RMS Scanning Heads

    The robust, field-proven RMS robotic scanning head has been successfully deployed on various assets such as storage tanks, pressure vessels, pipelines and other critical structures in harsh environments including oil and gas, offshore, mining and assets at temperatures up to 200°C.

    RMS-600 ideal for scanning rates on large surface areas such as tank shells, pressure vessels and other structures.

    RMS-450 is designed for operating circumferentially on curved surfaces such as pipelines or pressure vessels from 152 mm (6 inches) up to flat plate.

    RMS-300 a general purpose scanner for inspecting areas with limited access, vessel heads or other applications where smaller scan widths are required.


    R-Scan Array Manual Scanner

    The RMS integrates a detachable handheld manual scanner for the inspection of smaller areas and assets ranging from 4 inch (101 mm) to flat plate.

    The R-Scan Array can be purchased as an independent scanner, simply connect the scanner to a M2M instrument and you have a semi-automated phased-array corrosion mapping system with onboard data collection capabilities.

    Ideal for complex geometry components and restricted access areas the R-Scan array offers improved inspection dexterity and total battery operated portability.

    M2M Gekko PAUT

    M2M Instruments

    The cutting-edge M2M Gekko and Mantis phased-array systems have a growing reputation for being the most advanced phased-array instruments on the market. M2M is the first brand to deliver portable phased-array flaw detectors capable of driving matrix arrays and perform TFM in real time.

    Gekko phased-array ultrasound flaw detector is IP 66 allowing operators to bring it in the field without having to worry about rainy and dusty environments. Gekko supports extreme weather conditions.

    M2M Mantis Phased array

    Mantis is a light and economical version of Gekko using the same technologies and software interface Capture. With a 16:64 pulsers receivers architecture, Mantis combines standard PAUT, conventional UT, TOFD and real-time Total Focusing Method (TFM).

    Phased Array TFM Corrosion

    TFM imaging of corroded pipe work

    Real Time TFM

    TFM is a powerful technique that focuses at each point of a user-specified zone for accurate defect characterization and high-resolution imaging. Real-time imaging with speed of up to 30 frames per second can be achieved for the obtention of a clear image and defect contouring.

    • Optimal focusing and spatial resolution everywhere
    • Direct imaging of a large area for one probe position
    • All reachable angles with the array simultaneously
    • Defect characterisation
    • Comprehensive imaging of defect
    • 3D imaging

    Non-Intrusive Inspection (NII)

    This unique technology combination allows inspection versatility when performing non-intrusive inspections of pressure vessels and associated pipework. To complete a thorough NII inspection, there are requirements to perform a variety of advanced Ultrasonic Testing (UT) methods. In addition to corrosion mapping of the shell, the industry recommended practice is to perform Time of Flight Diffraction (ToFD) on welds, and manual phased-array for flange face and nozzle welds. With a RMS phased-array system, operators are now able to perform the full NII inspection by a simple change of probes.
