Out-of-range sounds from pressure control valves in a petrochemical plant are detected early

- Target sound: Pressure valve abnormal sound
- Key metric: Out-of-range sound (Normal-range deviation detection potential)

## Project overview

A case connecting abnormal sounds from repeated ultra-high-pressure valve operation to equipment safety diagnosis

## Field challenge

- Repeated bolt fracture history made early detection important
- Subtle movement and short operating cycles made normal/anomaly separation difficult
- The sounds can support plant safety diagnosis and pipe leakage diagnosis

## Outcome summary

- About 20 samples: Field sound analysis
- Out-of-range sound: Normal-range deviation detection potential
- Safety diagnosis: Plant abnormal sound analysis
