Gasoline Transfer Tank Leak Detection Methods
Visual Inspection
- Check for oil stains, beads, or mist on tank surfaces, welds, valves, and pipe connections
- Inspect sealing gaskets and flange connections thoroughly
- Monitor for paint peeling, expanding rust areas, or unexplained liquid level drops
Pressure Testing
- Seal all valves and introduce low-pressure gas into the tank
- Apply soapy water to suspected areas - bubbling indicates leaks
- Alternative method: Create negative pressure and monitor for pressure increases
Sensory Detection
- Identify persistent gasoline odors in operating areas/cabins
- Wear gloves to feel for sticky/wet surfaces on tank and pipes
- Wipe suspicious areas to check for fuel contamination
Instrument-Assisted Detection
- Use ultrasonic detectors to locate high-frequency leak sounds
- Add fluorescent tracer to fuel and inspect with UV light after operation
- Fluorescent markers reveal hidden leakage points
Abnormal State Monitoring
- Investigate unexplained sudden increases in fuel consumption
- Listen for "hissing" sounds near tanks during transport/operation
IMPORTANT: Immediately cease use and perform professional repairs upon leak detection to prevent safety incidents
