Graphite rupture discs for aggressive and corrosive fluids
Graphite rupture discs engineered to resist aggressive chemical media and corrosive process environments.
Rupture disks for high temperatures and aggressive fluids
In all those industrial plants where particularly aggressive fluids are processed, or again where operating temperatures are particularly high, graphite proves to be the best material to guarantee that installed bursting disks maintain a stable performance level, and do not lose in sensitivity even as the temperature rises.
DonadonSDD manufactures rupture discs in pure graphite, impregnated with phenolic resins to guarantee perfect non-permeability. Ideal for high-temperature applications, they however exhibit fragmentation upon rupture, a factor which must be considered when choosing whether to install them or other models.
