Manufacturer: 
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.
