Storage tank annular plates are high-risk areas because they are prone to corrosion from groundwater and foundation contact. Traditional inspection methods often fail to see underside damage without expensive excavation or decommissioning, but Phased Array Short Range Ultrasonic Testing (PASRUT) offers a more effective solution for identifying these critical flaws.
What this video covers
- Analysis of why annular plates are susceptible to failure due to their position at the tank foundation and exposure to moisture.
- Discussion of the limitations of conventional API 653 external visual inspections and internal floor magnetic flux leakage testing.
- Explanation of how PASRUT technology detects corrosion on the underside of the plate without requiring excavation.
- Overview of the benefits of using advanced ultrasonic testing to maintain asset integrity during both online and out-of-service periods.
This method allows for more accurate condition assessments of the most critical structural components of storage tanks.
