What are the consequences if the safety valve or rupture disc openings are made too large?

If the sizes of the safety valve openings and rupture disc openings are set too large, the following consequences may occur: 1. Increased safety risks: Excessively large openings for safety valves or rupture discs may not be able to discharge gas or liquid at high pressures in a timely manner, thereby increasing the risk of explosions, leaks, or other safety incidents. 2. Resource waste: Setting overly large safety valve or rupture disc openings can lead to excessive loss of gas or liquid, resulting in a waste of resources. 3. Unstable operation: Setting an excessively large safety valve or rupture disc opening can lead to unstable pressure control in the system, resulting in pressure fluctuations that are either too high or too low. 4. Increased costs: Installing overly large safety valve or rupture disc openings may require larger equipment or higher material costs, thereby increasing maintenance and operational expenses. In summary, to ensure the safe operation of the system, the sizes of the safety valve and rupture disc openings should be set appropriately to suit the actual operating conditions. .

As long as the safety inspection is passed, it’s fine; the design standards for safety valves only specify a minimum diameter, with no maximum diameter specified.

Wastes materials and increases costs. In principle, as long as safety can be ensured, the choice should be moderate.
