New ILI Service Introduced at IPC
At September’s International Pipeline Conference and Exhibition (IPC/IPE) in Calgary, the ROSEN Group, unveiled its premium inline corrosion detection service. RoCorr MFL-A Ultra is based on ultra-high-definition axial magnetic flux leakage (MFL-A) technology, and will enable the detection and reliable sizing of both minuscule pipe defects and complex defect groups.
Unlike current MFL inline inspection services, RoCorr MFL-A Ultra detects even the smallest defects in the pipe wall, such as pinholes of one millimeter (0.04 inches) and less in diameter. Furthermore, it defines the exact structure of defect groups and complex corrosion like preferential girth weld corrosion, top-of-the-line corrosion (TOLC), pinholes in general corrosion, pinhole colonies, and microbiologically induced corrosion (MIC).
This is made possible through the combination of two highly innovative technologies:
- Pipeline Imaging™, a fully triaxial design of ultra-high-definition 3D MFL sensors, delivering the highest in-line inspection resolution available on the market
- AutoData™, machine-learning, adaptive algorithms calibrated using high-resolution. 3-D laser scans of real pipe defects.
While Pipeline Imaging™ provides lifelike pictures of a pipe wall’s structure similar to images known from MRI scans of the human body, AutoData™ automatically processes large amounts of data within seconds, thereby increasing the accuracy and repeatability of results significantly.
The RoCorr MFL-A Ultra service provides a comprehensive and accurate understanding of a pipeline’s structure. This allows for less conservative integrity assessments that minimize field verification expense and optimize an assets performance.
