Rupture discs: technical guide in Spanish

A rupture disc is a non-reclosing pressure relief device: a calibrated membrane that bursts at a defined pressure and temperature to protect vessels, piping and valves against overpressure. On this portal we explain, in engineering language and without detours, how they work, what types exist, how they are selected, which standards apply and how they are installed and maintained.
