Rupture disc GA Graphite Discs
Safety · Rupture Discs
Manufacturer: 
DonadonSDD offers GA rupture discs that are designed to protect industrial plants where particularly aggressive fluids are processed from sudden pressure variations that can cause severe damage. GA Rupture Discs can be mounted directly between flanges and are manufactured in pure graphite, impregnated with phenolic resins to guarantee perfect non- permeability. By the nature graphite bursting discs will fragment upon bursting.
