Blowout discs for electronic gas circuits
Thread Content
Safety pressure relief devices are necessary for gas pipelines. I previously purchased domestic rupture discs, which appeared to be of poor quality; their inner surfaces were rough, and their sealing design did not match that of the EP-grade pipe valves used in electronic gas systems. Are there any brands that offer high-quality small rupture discs (with a diameter of around 20 mm) that I could recommend?
Should it be connected by bolts or flange clamping?
The estimated leakage rate for threaded connections, which use flange clamps, is too high
Let’s check whether the flange standard used for the rupture disc at that time was incorrect; also, it’s quite rare to hear about rough surfaces on domestically produced rupture discs
The inner surface roughness of the pipes, elbows, valves, etc. that we use is around 0.3 um; the surface roughness of the rupture discs hasn’t been specially treated to reach this level
