Pressure valve abnormal sound
Petrochemical plant safety diagnosis
H Company gas and pressure valve sound analysis
Out-of-range sounds from pressure control valves in a petrochemical plant are detected early
Target sound
Pressure valve abnormal sound
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
