key advantages

  • Accurate and precise feature classification and sizing by magnetic saturation, high sensor density, high sampling rates and triaxial magnetic field analysis.
  • High precision geometry mapping and dent sizing using contour following sensor technology even at tough operational conditions.
  • Accurate discrete stress and strain gridding derived from high resolution inspection raw data.
  • Quantitative determination of scale, debris and wax achieved by touch less pipeline surface sensing.
  • Lifetime integrity management supported by full recording of the complete inspection raw data.
  • High availability and a wide range of proven tool configurations addressing individual operational pipeline requirements.
  • High quality service with certified processes (API 1163), personnel qualification (ASNT) and equipment (CE, ATEX).

The Solution

The RoCombo MFL-A/XT includes not only a Magnetic Flux Leakage unit but also a combination of mechanical calipers with an electronic measurement system based on the Eddy Current principle. This innovative combination enables the RoCorr to check for both, metal loss and geometry anomalies in only one inspection run. Unique magnet and sensor designs ensure high sensitivity and precision for the detection of corrosion, erosion, gouging and a huge variety of other metal loss features.

The tool measures depth, profile and contour of geometric features, allowing a stress/strain based integrity assessment. XYZ Mapping coordinates for advanced integrity management is available optionally.
