What is Corrosion Mapping with RMS?
An ultrasonic scanning technique providing high‑resolution thickness measurements and corrosion profiles. High Speed, High Accuracy Corrosion Mapping
Method of Inspection | Applications
Used for remaining life assessment and monitoring corrosion patterns in pipes, vessels, and tanks.
RMS2 is designed to evaluate the condition of storage tanks, pipelines, pressure vessels and other critical equipment, supporting the integrity management processes to ensure effective and safe operation
RMS2 can give 100% coverage in a band up to 450 mm wide, significantly increasing Probability of Detection (POD) of defects and corrosion, enabling engineers to determine the optimum repair strategy and improve remaining life assessment (RLA) & risk-based inspection (RBI) maintenance programs.

Reporting & Deliverables
ADVANCED DATA ACQUISITION AND ANALYSIS SOFTWARE
Intuitive design with floating gates for greater accuracy, real-time A-Scan and C-Scan display, advanced defect sizing tools with increased re-analysis speed for efficient data investigation.
ACQUISITION AND ANALYSIS SOFTWARE
RMS2 software integrates scanner control, data capture, data analysis and reporting tools. The software shows a real-time display of the ultrasonic A-scan, C-scan, thickness measurement and positional data, with a maximum resolution of 0.5 mm x 0.5 mm. All of this information is recorded when a scan is saved.
FLOATING GATES & A-SCAN PROCESSING
A-scan waveform processing is fully digital, both in real time and during post processing. The system records A-scans in raw RF unfiltered form, which can then be processed afterwards, including rectification, filtering, wave smoothing and noise reject. This minimizes the set up on site and avoids re-scanning due to incorrect ultrasonic setup. Floating gate “tracks” to the same % of the signal amplitude. This allows signals to be picked up which are much lower in amplitude improving the accuracy and increasing the efficiently of data analysis and reporting with greater inspection confidence.
B-SCAN AMPLITUDE
The B-scan amplitude view shows the B-scan profile in both X and Y dimensions at a selected point of the C-scan. Using the B-scan amplitude view, the operator can easily identify any defects or inclusions. Reviewing acquisitions in B-scan mode makes it easier to see indication such as small pits and inclusions.
C-SCAN LAYERS & MULTIPLE A-SCAN GATES
The intuitive software is designed around the concept of C-scan ‘layers. This allows the operator to quickly switch between each of the multiple C-scan views generated. During an inspection, the A-scan trace, B-scan amplitude view and resulting C-scan image are shown within the software in real time providing immediate inspection feedback. Multiple A-scan gates can be added to measure between several parts of the A-scan trace. This means it is possible to measure the signal amplitude, part thickness, internal surface profile and external surface profile simultaneously.
CMAP REPORTING
CMAP can import data from a range of inspection systems building up an overall view of an inspection irrespective of the plant item being scanned e.g. storage tank shell or roof, pressure vessel, road tanker or marine vessel to name a few. RMS2 data can be automatically positioned and “stitched” together based on scan co-ordinates, this significantly reduces time in analysing inspection data. CMAP also contains dimension tools to annotate defect areas. These dimension markers can overlap different scans and be used for defect sizing or adding positional information.
