KRD Sanitary Rupture Discs – Advanced Pressure Protection for Hygienic Industries
DonadonSDD’s KRD reverse acting rupture discs are critical safety devices that protect your industrial plant by preventing sudden pressure build-ups. 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 KRD rupture discs uses advanced sector technology and provide targeted and precise protection in the most demanding applications making DonadonSDD KRD rupture discs an optimal safety choice for plants dealing with extreme conditions. Its specific design makes the KRD ideal to offer pressure protection to equipment where Full Liquid fluid is present. Keyfeatures & technical benefits State-of-the-art Design: Particularly suitable for the Pharmaceutical, Food, and Biotechnology industries, and represents the advanced for these sectors. FDA-Certified Gaskets: PTFE gaskets, which are certified in compliance with FDA and USP class VI, 3-A, and Eu 10/2011 regulations, facilitate installation in Clamp fittings (sanitary, Tri-Clamp, Tank Connection). Hygienic Applications: Designed to meet the high-quality standards required by 3-A SSI, GMP and MOCA to ensure public health through hygienic equipment. High Certification Standards: Our KRD rupture discs have achieved the highest certifications, including ASME XIII (UD STAMP), 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: KRD rupture discs obtained using our patented Laser NS NanoScored technology are reverse-acting discs with micro-scored calibrated sections opening around the circumference, reducing the risk of petal detachment. Reliable Performance: Withstands thousands of cycles without compromising their reliability, with ratios up to 95% between operating and rupture pressure. Rapid Non-Fragmenting Rupture: The disc opens completely in a few milliseconds along a circumferential line scored on the downstream side of the disc, thus preventing fragmentation from forming. Versatile Design: Suitable for presence of 100% liquid, cycling, and pulsating conditions without reducing safety margins. Corrosion-Resistant: Wide range of materials and thickness options; PTFE or PFA lining (FDA Approved) available for added protection. High Pressure/Vacuum Resistance: Does not require vacuum support, avoiding restrictions in the discharge area; capable of resisting high backpressures. Why Choose DonadonSDD? Advanced technology and advanced design ensure precise and dependable pressure protection for hygienic industries. Stainless steel construction, smooth surface, and FDA-certified gaskets ensure high levels of hygiene and aseptic conditions. Smooth Surface: Smooth surface finish (0,2<Ra<0,4 micron) makes it particularly suitable for C.I.P. and S.I.P. treatments to maintain aseptic conditions. Roughness Test available for even lower values. Can be used with full liquid applications and can resist both vacuum and high operative pressure.
R.S.T. - Rupture Stream Test
Managing instances of excessive pressure in industrial plants is a basic element of safety both for structures and technicians. Rupture discs are, as of today, the perfect tools to guarantee complete safety.
SCD Rupture Discs – Precision Pressure Protection for Industrial Plants
DonadonSDD’s SCD forward acting rupture discs are vital safety devices that prevent sudden pressure variations from damaging industrial plants. Forward acting rupture discs have a concave disc camber that remains unaltered under operating pressure until set pressure is reached and this can ensure long service life. DonadonSDD’s SCD rupture discs provide reliable and precise protection in the most various and demanding applications, making DonadonSDD SCD rupture discs the best choice for your plant’s safety. SCD forward acting rupture discs are one of the most versatile discs: usable for every type of fluid flow, ideal for polymerization process, able to reach a wide range of pressures. Keyfeatures & technical benefits High Certification Standards: Our SCD rupture discs have achieved the highest certifications, including ASME XIII (UD STAMP), 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: SCD rupture discs obtained using our patented Laser NS NanoScored technology is a compression-loaded forward-acting discs with micro-scored calibrated sections opening in petals, reducing the risk of petal detachment. Reliable Performance: Withstands thousands of cycles without compromising their reliability, with ratios up to 85% between operating and rupture pressure. Rapid Rupture: Discs react to excessive pressure in a few milliseconds with full opening along petals lines scored on the downstream side of the disc. High Bursting Pressure: Especially suitable for high bursting pressure; can be used with both gas and liquids, in various industrial processes, in cycling and pulsating conditions without reduction of safety margins. Pressure Safety Valves isolation / Non-Fragmenting: Especially suited for protection of Pressure Relief Valves due to ruptures along the scored line without generating fragments. Corrosion-Resistant: Wide range of materials and thickness options; PTFE lining available for added protection. High Vacuum Resistance: Can, in many cases, be subject to absolute vacuum conditions without the need for supports, avoiding restrictions in the discharge area. O-Ring seal available for reduced fugitive emissions Why Choose DonadonSDD SCD Rupture Discs? Certified to the highest industry standards for maximum safety. Manufacturing Range = ZERO (included with ASME) Krgl (ASME-Certified velocity head loss) = 1.33 Can be used in double-holder configurations. Advanced technology and precision design ensure dependable pressure protection for industrial applications. Rapid rupture and pressure relief capabilities ensure maximum safety for industrial applications. Corrosion-resistant design and PTFE lining options ensure longevity and reliability.

DonadonSDD introduces the new NS NanoScored series Burst Discs, a further development of its breakthrough technology. DonadonSDD has also been awarded both a US patent and an Italian for the innovative NS NanoScored rupture disc manufacturing method. NS NanoScored series rupture discs are fully metallic and adequate for all applications. The NS Nanoscored rupture disc series includes tension rupture discs (forward acting) like SCD discs and compression discs (reverse buckling) like SCR discs (petals) or Y90 and KRD (opening on circumference). The new manufacturing technology developed by DonadonSDD allows for rupture discs as follows: Fully metallic (Stainless steel, Nickel, Inconel, Monel, Hastelloy, Titanium, Tantalum) Full range of diameters from DN 1/2” (15) to DN 36” (900) Absolute reproducibility given that there is no deterioration of tools Resistance to fragmentation even for high rupture pressures Resistance to absolute vacuums without need for supports Characterised by full design flexibility For bursting pressures below 0.5 bar g (7 psi g) also for DN 1”1/2(40) High accuracy at all rupture pressures Reduced rupture tolerance according to customer requirements Suitable for insertion in standard or sanitary (Tri-clamp) disc holders The new manufacturing technology developed by DonadonSDD allows for the manufacturing of scored rupture disks also with very low thickness materials (basically with every industrially available thickness), ensuring high reliability and strict tolerance. It is therefore possible to extend the range of bursting pressure available to lower bursting pressure than normally available.
