# Ultrasonic Testing Enables Safer Refinery Startup

Before reintroducing hydrofluoric acid following a major turnaround, a Gulf Coast refinery needed confidence that its HF Alkylation unit was completely leak-free. Ultrasonic testing uncovered four leaks that traditional methods would have missed, including leaks at elevated locations and those obscured by background noise. By identifying and addressing each issue before startup, the refinery achieved zero leaks while reducing pre-startup testing time. Download the case study to see how ultrasonic testing improved safety, accelerated startup and became a standard practice for future turnarounds.
