DONADON SCD Rupture Disc

DONADON SDD SCD rupture discs DONADON SDD SCD Rupture discs obtained with NS Nanoscored technology are discs with micro-scored calibrated sections opening in petals, characterised by the presence of 4, 6 or more radial scoring. This allows for better opening reducing the risk of petal detachment. This makes Donadon SDD SCD rupture discs especially suitable at high bursting pressure. They are used with gas and liquids also in cycling and pulsating conditions without reduction of safety margins. SCD discs react to excessive pressure in a few milliseconds without fragmentation. They are especially suited for protection of pressure relief valves. Donadon SDD SCD rupture discs allow for a ratio between operating and bursting pressure up to 85% and have a very good resistance to corrosion. Corrosion resistance may be additionally improved with PTFE lining. In addition, SCD discs can, in many cases, be subject to absolute vacuum conditions without need for supports.
