We had several discharged of inergen system on our substations. There were three such occasion wheres two of the incident had pipe dislodged.
I was asked by my superior how did that happen? I understand that the pipe pressure test was only 40 psi for 10 minutes and the pressure inside the pipe could be about 60 bar.
We are using inergen system with iFlow valve.
Could somebody point out to me, where should i be looking at to know how did the pipe got dislodged during the accidental release?
