How to ensure the safe operation of pressure vessels?

I. Process Parameter Monitoring

1. Pressure Control: Real-time monitoring using pressure gauges to ensure pressure does not exceed design pressure. In case of overpressure, release pressure via safety valves or vent valves.

2. Temperature and Level: Thermometers monitor medium temperature, and level gauges maintain stable liquid levels to prevent thermal stress or abnormal liquid levels from affecting load-bearing capacity.

3. Medium Composition: Regularly analyze the composition to prevent impurities from causing corrosion or explosion risks.

II. Safety Device Inspection

1. Safety Valves and Rupture Discs: Regularly calibrate opening and closing pressures to ensure sensitivity and reliability.

2. Pressure Gauges and Interlocking Devices: Check instrument accuracy; interlocking systems must be effectively operational.

III. Overpressure Sign Identification

1. Process Abnormalities: Continuous rise in pressure/temperature, liquid level fluctuations exceeding range.

2. Equipment Status: Vessel deformation, weld cracks, leaks at connections, or abnormal vibration.

IV. Regular Maintenance

1. Daily Inspection: Check pressure, temperature, leakage, and the status of safety accessories; record operating parameters.

2. Preventive Maintenance: Measure wall thickness quarterly; conduct a comprehensive annual inspection (including magnetic particle testing).

3. Personnel Training: Operators must be certified and complete 24 hours of professional training annually.
