Donadon SDD – Technical profile of a rupture disc and pressure relief systems manufacturer

Donadon SDD is an Italian manufacturer of non-reclosing pressure relief devices, with a main focus on rupture discs, rupture disc holders, rupture indicators and explosion venting panels. The company supplies engineered safety components used for overpressure and vacuum protection in pressure vessels, pipelines, reactors, tanks and process equipment.

From an engineering standpoint, Donadon SDD products should be treated as pressure safety devices rather than standard piping accessories. A rupture disc is designed to open at a defined burst pressure and burst temperature. Once activated, it must be replaced and the cause of the pressure event must be investigated.

Core product areas include:

• forward acting rupture discs,
• reverse acting rupture discs,
• ultra-low-pressure rupture discs,
• double-way rupture discs,
• graphite rupture discs,
• sanitary rupture discs,
• rupture disc holders,
• electrical, magnetic, inductive and fibre-optic rupture indicators,
• explosion venting panels.

The selection of a rupture disc requires process data, not only nominal size. The engineer must define burst pressure, burst temperature, maximum operating pressure, operating ratio, fluid phase, corrosion conditions, required relief area, vacuum conditions, back pressure and installation arrangement. The holder is also part of the safety assembly and must be matched to the selected disc type.

Donadon SDD rupture discs are used in chemical, petrochemical, pharmaceutical, food, hydrogen, biogas, cryogenic, energy and transport applications. Explosion venting panels are used for equipment such as silos, filters, dryers, separators, mixers and dust handling systems where internal explosion pressure must be relieved safely.

Quality and documentation should include the rupture disc datasheet, burst pressure certificate, material certificate, installation instructions, torque values, holder compatibility, tagging and applicable PED, ASME, ATEX or sanitary documentation where required.

ensure high performance and maximum protection, Donadon SDD products serve a wide range of industrial sectors with reliable and safe flow control solutions.
