CHEMICAL / PETROLCHEMICAL

There are many kinds of chemical plants where it is easily possible for an undesired chemical reaction to bring on an uncontrolled rise in pressure, which is not acceptble: examples may lie with desulfonation and hydrogenation reaction circuits, with chillers, and with heat exchangers. This is one of the most classic and time-tested applications of rupture discs.

In these applications, where the disc must bear operating pressures very close to those requiring it to rupture, the suggested models are surely reverse rupture discs, such as models SCR e Y90, which sport a particular construction giving them the required high operative margin.
