Automated UT Corrosion Mapping (AUT)

High-resolution ultrasonic corrosion mapping for accurate wall-thickness measurement, flaw detection, and degradation monitoring across industrial assets.

Advanced Automated Ultrasonic Corrosion Mapping

Our Automated UT Corrosion Mapping (AUT) services provide precise, high-speed, and repeatable thickness measurements using automated scanners and advanced ultrasonic technology. AUT delivers comprehensive visual maps of corrosion, erosion, pitting, and wall-loss patterns—allowing engineers and facility operators to make informed decisions regarding repairs, replacements, and long-term asset integrity. AUT is essential for piping, pressure vessels, storage tanks, and critical equipment operating under demanding industrial conditions. We support Mechanical Integrity (MI), Risk-Based Inspection (RBI), API programs, and quality assurance for piping, pressure vessels, tanks, structural components, and industrial assets. PAUT delivers faster, clearer, and more reliable results than conventional UT

What Is Automated UT Corrosion Mapping?

AUT corrosion mapping uses automated or semi-automated ultrasonic scanning systems to collect thousands of thickness readings over a defined area. Unlike manual UT, AUT offers:

  • High-density data collection

  • Accurate and repeatable readings

  • Full-area corrosion visualization (A-, B-, C-scan)

  • Faster inspection of large surfaces

  • Better detection of pitting, local thinning, and hidden flaws

This method significantly improves the reliability of corrosion monitoring programs.

Why Facilities Choose AUT

  • Industrial assets face continuous degradation from temperature, pressure, flow, and environmental exposure. AUT helps facilities:

    • Monitor corrosion progression

    • Identify high-risk areas early

    • Extend equipment life

    • Avoid leaks, failures, and production downtime

    • Support API, ASME, and mechanical integrity compliance

    • Plan turnarounds with accurate data

Our AUT Inspection Process

Every piping system undergoes strict QA/QC and inspection protocols:

1. Assessment & Surface Preparation

We evaluate inspection areas, access, geometry, and coating conditions. 

2. Automated Scanner Setup

  • Placement of automated crawlers or encoded scanners for precise scanning paths.

3. Data Collection & Acquisition

High-density ultrasonic data gathered using multi-scan modes (A-, B-, C-scan).

4. Data Analysis & Interpretation

Certified technicians and Level II/III analysts review thickness maps, identify corrosion patterns, and classify severity.

5. Detailed Reporting

Reports include:

  • C-scan corrosion maps

  • Minimum/maximum wall thickness

  • Pit depth & localized thinning

  • Corrosion profile comparison

  • Repair recommendations

  • Re-inspection intervals
