Pressure vessel rupture
A pressure vessel rupture poses a catastrophic risk to your facility, potentially causing severe structural damage and endangering your entire team. Implementing rigorous oversight and proactive maintenance is essential to ensure your equipment remains within safe operating limits and prevents unexpected failures.
About 78% of related real accidents concentrate in these types.
Key prevention
- Conduct regular visual inspections to identify signs of corrosion, pitting, or physical deformation on the vessel shell.
- Ensure all pressure relief valves are tested periodically to confirm they open correctly before internal pressure reaches dangerous levels.
- Maintain a strict schedule for professional ultrasonic thickness testing to monitor for thinning walls that could compromise structural integrity.
- Verify that all pressure gauges are calibrated and clearly marked with the maximum allowable working pressure to prevent accidental over-pressurization.
- Establish a comprehensive training program so that all operators can recognize early warning signs of equipment distress and understand emergency shutdown procedures.
