Rupture Disc / Burst Disc for Storage Tank
Rupture Disc / Burst Disc for Storage Tank
(OP)
Hi,
May I know, in normal operations, will the rupture disc/burst disc installed on the tank's vent line ALLOW the gas to flow through it, as long as the pressure in the line is lower or within its burst pressure, as a mean of +pressure breathing?
In this case, during re-filling of raw materials into the tank, with N2-Blanket.
Thank you for your input, in advance.
Cheers!

Bursting discs are a use once only device to provide very fast operation large relief flow to prevent overpressure from a very fast or very high flow unexpected event, not a normal operation like filling and discharging.

RE: Rupture Disc / Burst Disc for Storage Tank
We recently had an occurrence of a ruptured burst disc, occurred due to the tank's drying with compressed air.
The tank is located in the cold room, with N2 blanketing.
Burst Disc rating at +0.6 Barg @ 6 degC. May I know what is the rated temperature 6 degC actually referred to? Differential Temperature or the actual temperature the burst disc is exposed to?

The burst disc ruptured when drying work was commencing with dry compressed air, set at 1 BarG, and the possibility of due point valves were still in closed position. There was a delay in our alarm signal system that it picked up the signal of the burst too late.
