DonadonSDD SCR reverse acting rupture discs are essential safety devices that prevent sudden pressure variations from damaging industrial plants. Reverse acting rupture discs have a convex disc camber that remains unaltered under operating pressure until reverse pressure is reached and this can ensure long service life. DonadonSDD SCR rupture discs uses advanced sector technology and provide improved performance and reliability to offer precise protection in the most high-risk applications, making DonadonSDD SCR rupture discs the best choice for your plant’s safety. Our SCR Rupture Discs are specifically designed to protect steam condenser systems from overpressure. The discs feature a full metal design with micro-scored laser sections that ensure high reliability, strict tolerance, and improved efficiency of the vacuum system. The use of a PTFE seal membrane, which is notoriously permeable, is no longer required.
Keyfeatures & technical benefits
High Certification Standards:
Our SCR rupture discs are certified to the highest safety standards, including PED 2014/68/UE (CE STAMP), ATEX EX II 2 GD (CE STAMP), PER 2016 UK Statutory Instruments 2016 No 1105 (UKCA STAMP), and CU TR 032 (EAC STAMP).
Advanced Technology:
SCR rupture discs obtained using our patented Laser NS NanoScored technology are reverse-acting discs with micro-scored calibrated sections opening in petals, reducing the risk of petal detachment.
Versatile Design:
Designed for easy installation in customer’s flanged coupling (or with additional spacer rings to adapt at the existing space between flanges and provide easy installation) and has a long lifespan under cyclic and pulsating pressures.
Reliable Performance:
Withstands thousands of cycles without compromising their reliability, with ratios up to 95% between operating and rupture pressure. Strict tolerance on the bursting point ensures reliable protection.
Rapid Rupture:
Disc ruptures in a few milliseconds and with full opening along scoring petals lines on the downstream side of the disc.
Non-Fragmenting:
DonadonSDD SCR Rupture Discs ruptures along the scored line without generating any fragments.
Temperature Resistance:
ideal for applications with significant temperature variances due to reduced sensitivity to temperature fluctuations.
Vacuum Resistance:
Full vacuum resistant, providing a full vent area without the need for vacuum support.
