Let’s discuss what to do if the burst disc fails to rupture
Thread Content
Regarding low-temperature containers, let’s discuss what would happen if the rupture disc fails to burst – isn’t that very dangerous? Are there any other measures to ensure the safety of the container, such as safety valves?
In the event that the burst disc does not rupture, only the container will burst. But this situation is unlikely to occur, as the rupture disc will at most have a slight deviation in its burst pressure; it won’t be that significant, after all, the water pressure is 1.25 times higher. Safety valves are not suitable for use in some situations.
A safety valve can be used, or a safety valve and a burst disc can be connected in series. If the safety valve fails, an accident will inevitably occur; the causes of the accident can then be analyzed
Generally, there shouldn’t be such a problem, right, OP?
The strength of the burst disc will in no case exceed that of the container’s thin walls! In the event of a failure to explode, there are safety devices such as safety valves and pressure gauges.
Why doesn’t the rupture disc in LZ burst? Generally, a rupture device can be used in combination with a safety valve.
1. If this situation occurs during the operation of the container, the first thing to do is to shut it down urgently! The second step is to replace the blast disc, and the third step is to investigate the cause of overpressure. . . . 2. If this situation is taken into account during the design phase, it is recommended to use a combination of safety valves and rupture disks. For reference!
Blowout discs have a limited lifespan and need to be replaced on time; the quality of today’s blowout discs should be fine.
Use in parallel with a safety valve, with an opening pressure slightly higher than that of the rupture disc
I agree with what was said above. Generally speaking, the burst disc is the last line of defense; another form of protection is the safety valve. These two work in parallel, providing dual protection to ensure safety!
