Chemical & Petrochemical industry pressure safety with custom rupture discs
High-precision rupture discs engineered for corrosive, high-temperature and continuous process environments.
Reliable protection for complex chemical processes.
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.
Frequently Asked Questions
Depending on disc’s type, DonadonSDD can supply discs from 1/8” (3mm) up to 40” (1000mm) in diameter.
You can download here the RUPTURE DISC FORM that will guide You to collect all the data required, which can be also summarized as below specified:
- required burst pressure & burst temperature
- nominal size, flange rating & face finishing
- disc and holder material
- vacuum resistance (if requested)
- Pressure Safety Valve protection (if requested)
There are several other factors as well, so DonadonSDD specialists are always at disposal to specify the correct disc for any application. Each and every rupture disc we design and deliver to our customers is scrupulously custom-built, so as to match the industrial plant’s specific and unique needs.
