GA Rupture Discs – Safety Devices with High Purity Graphite Material

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.

Keyfeatures & technical benefits

High Certification Standards:

Our rupture discs are certified to meet the highest international standards, including PED 2014/68/UE (CE STAMP), PER 2016 UK Statutory Instruments 2016 No 1105 (UKCA STAMP), and CU TR 032 (EAC STAMP).

Technique:

Mounted on a stainless-steel ring, combining the mechanical strength of a steel holder and the characteristics of graphite discs.

Easy Installation:

Can be directly inserted between flanges.

Features:

Opening is total but with fragmentation; resistant to aggressive fluids (can be protected with a PTFE or PFA membrane too) and low bursting pressure sensitivity to temperature variations.
