Compression rupture disc SCR
برند:
Donadon SDD
مشخصات:
DonadonSDD SCR Rupture discs obtained with NS Nanoscored technology are compression or reverse 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 DonadonSDD SCR rupture discs suitable both at high and at low bursting pressure and can be used only with gas and liquids (with the presence of a special gas cushion) also in cycling and pulsating conditions without reduction of safety margins.
SCR discs react to excessive pressure in a few milliseconds without fragmentation.
They are especially suited for protection of pressure relief valves.
DonadonSDD SCR Nanoscored rupture discs allow for a ratio between operating and bursting pressure up to 95% and have a very good resistance to corrosion. Corrosion resistance may be additionally improved with PTFE lining. In addition, SCR discs can be subject to absolute vacuum conditions without need for supports
