1. Breather Valves & Venting Systems
- Primary safety components – venting capacity designed based on material properties and filling/discharge volumes.
- Vents excess gas during positive pressure (temperature rise or oil intake).
- Draws in air during negative pressure (temperature drop or oil discharge).
- Maintains internal pressure within safe range.
2. Mechanical & Hydraulic Safety Accessories
- Additional mechanical breather valves – installed on tank roof to increase venting capacity.
- Keep hydraulic safety valves and flame arresters in good working order.
- Act as secondary defense – intervene rapidly if primary breather valve fails.
- Prevents pressure loss of control under extreme conditions.
3. Filling/Discharge Operations & Process Management
- Strictly control valve openings and pump flow rates – avoid sudden pressure spikes or drops from excessive instantaneous flow.
- Regularly inspect inlet/outlet pipelines for obstructions.
- Clear blockages promptly to ensure smooth gas and liquid flow.
- Prevents safety hazards caused by pressure buildup.
4. Inspections, Maintenance & Pressure Monitoring
- Include in regular inspection schedules – use pressure gauges to monitor internal pressure in real‑time.
- Assess pressure‑bearing capacity for aging tanks; reinforce or retrofit as needed.
- Regular cleaning and maintenance of breather valves to prevent sticking or clogging.
- Ensures pressure regulation mechanism remains responsive and reliable.
