The Role of Ultrasonic Testing in Preventive Maintenance for Industrial Assets
Preventive maintenance isn’t just a best practice—it’s the foundation of industrial reliability. And when it comes to non-destructive inspection, few tools offer the precision and repeatability of ultrasonic testing (UT).
Whether you’re monitoring tanks, pressure vessels, pipelines, or rotating equipment, ultrasonic NDT helps detect flaws before they turn into failures—saving time, money, and unplanned downtime.
Why UT Matters in a Preventive Maintenance Program
Preventive maintenance relies on accurate, real-time data to identify degradation early. Ultrasonic testing provides just that—quantitative measurements of wall thickness, internal cracking, corrosion, and other anomalies.
Key reasons UT is essential in PM programs:
- Early Detection of Wall Loss: Identify thinning from corrosion or erosion before structural integrity is compromised.
- Crack Monitoring: Detect internal cracks like hydrogen-induced cracking (HIC) or stress corrosion cracking (SCC) with B-scan and amplitude view data.
- Baseline Mapping: Compare data over time to track asset wear and degradation trends.
- Compliance: Meet regulatory standards such as API 653, B31G, or ASME code requirements without destructive methods.
Common Use Cases for UT in Maintenance
UT is especially effective in high-risk, high-value industrial systems. Common applications include:
- Storage Tanks: Track thinning of shell walls, floors, and roofs
- Pressure Vessels: Detect internal cracking, delamination, and loss of thickness
- Pipelines: Identify localized pitting, weld defects, and general corrosion
- Paper Machines: Measure dryer roll thickness in pulp and paper mills
- Power Generation Equipment: Inspect boilers, turbines, and heat exchangers
