Donadon Safety Discs and Devices has always been investing in research and development and in the acquisition of production plants equipped with leading-edge technology. The result of these developments is the NS Nano Scored series of rupture discs, which are now available in accordance with ASME Directives, Section VIII, Division 1, and bear the matching UD stamp.
Donadon SDD’s range of NS Nano Scored microscored discs has offered the possibility to produce an innovative product portfolio to protect chemical and petrochemical plants against pressure peaks. These are all-metal rupture discs, very accurate and reliable, customizable to customer needs for a wide range of diameters and pressure ratings. With their all-metal design, NS Nano Scored discs are particularly suitable also for all applications in aseptic environments, including pharma, food and biotech.
With their new manufacturing processes, Donadon SDD can produce rupture discs with leading-edge technical features. Here a just a few examples: all metal construction with a wide range of materials; fragmentation-proof even at high bursting pressure; fully reproducible as the production tools are wear-free; very accurate. In many cases, Donadon SDD NS Nano Scored discs can be provided with intrinsic vacuum resistance, with no need for supports.
SDD rupture discs are easy to install, airtight, versatile and free of maintenance, except when they must be replaced following their “action”. NS Nano Scored discs offer high ratios between operating pressure and rupture pressure, excellent resistance to corrosive agents, also thanks to PTFE coatings, and response to overpressure within few milliseconds.
