Problems with gas cylinders having built-in safety relief devices
Thread Content
1. Is the relief device of an acetylene cylinder a fusible alloy plug? It’s like a rupture disc; once it releases, all the gas will be let out – isn’t that dangerous? 2. Is the relief device on a cryogenically liquefied Dewar a fusible alloy plug? It seems inappropriate to use fusible alloy plugs for these two types of gas cylinders; I’m not sure about the actual situation, so I’d like some advice.
They all belong to the type of rupture discs; they are all specialized spare parts. It can be replaced at any time. The principle is that excessive pressure causes it to rupture in order to release pressure. No other safety hazards will arise. Also, for storage use, just follow the specifications.
The principle of the fusible alloy plug is not overpressure relief, but overtemperature relief.

You think it’s unreasonable; I think it’s due to the overpressure release principle. Specifically, what materials he uses—these are all specialized parts, products with fixed specifications. It’s hard to say when it’s labeled as “fusible”; let’s see what the experts have to say.
