Rupture disk-can it burst from the other side?
Rupture disk-can it burst from the other side?
(OP)
Hi Folks,
It may be a silly question, but there is a discussion about RD bursting. I am wondering if in case of superimposed back pressure bigger than set pressure of RD, the disc can rupture and relief into a tank.
Let me explain the situation. Rupture disk is installed on the tank and discharge pipe is hooked into vent header. RD's set pressure is 3.45 barg. But there may be situation that in the vent header pressure may be significant bigger (ca 40 barg) during the depressurization of other equipment hooked up to the same vent header. The question is if in this case the disk may rupture?
Thanks
Robert

(28 Feb 2007) report. This will show you bursting discs can fail in reverse. This particular incident had almost catastrophic consequences.

I agree with everybody.
The only thing I would like to ask is, did you say
¿¿40 bar??

Just don´t think about if it breaks from the back.
You must see the situation as if you were establishing a potential overpressure scenario because of the header pressure in the discharge side of the disc.
Do you see my point?
You always design a relief device imaging the worst scenario, in this case, discharging to a high pressure header, you are adding a potential cause of over pressure.
