Probe Inspection

TechCorr provides high-precision ultrasonic probe inspection designed to evaluate the physical integrity of atmospheric storage tank floors, annular rings, and shell courses. Utilizing advanced automated raster crawlers paired with targeted manual probe techniques, our inspection protocols capture high-resolution wall thickness profiles and quantify both internal product-side corrosion and soil-side degradation. By deploying dual-element, delay-line, and multi-element probe configurations, our certified technicians obtain quantitative thickness profiles without requiring destructive surface preparation, enabling operators to identify critical floor thinning and localized pitting prior to failure.

Key Capabilities

• Automated ultrasonic raster scanning for comprehensive corrosion mapping of tank bottom plates and critical shell courses.
• Targeted manual probe thickness verification to quantify deep isolated pitting and soil-side accelerated degradation.
• Annular ring ultrasonic examination using specialized angled and low-profile probes to evaluate high-stress boundary zones.
• Comprehensive wall thickness data collection integrated into detailed corrosion rate assessments and remaining life calculations.
• Rapid in-service and out-of-service deployment schedules configured to minimize asset downtime and turnaround windows.

Compliance & Standards

All probe inspections and data analyses are executed strictly in accordance with recognized industrial engineering codes, including API 653 (Tank Inspection, Repair, Alteration, and Rerating), API 650 (Welded Tanks for Oil Storage), ASME Section V (Nondestructive Examination), ASTM E797 (Measuring Thickness by Manual Ultrasonic Pulse-Echo Contact Method), and ISO 16809. Visual and geometric assessments comply with AWS standards, while corrosion risk evaluations reference NACE/AMPP guidelines.

Through our network of global locations and multi-disciplined NDT teams, TechCorr delivers clear thickness distribution maps, risk-based analysis, and defensible remaining-life evaluations that protect terminal storage infrastructure against costly environmental contamination and operational interruption.
