GR Rupture Discs – Safety Devices with High Purity Graphite Material

DonadonSDD offers GR rupture discs that are designed to protect industrial plants where particularly aggressive fluids are processed from sudden pressure variations that can cause severe damage.
GR Rupture Discs have to be used together with specific holders and are manufactured in very high purity 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).

Vacuum Resistance:

A vacuum support is required for rupture pressures below 1.7 bar g.

Features:

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

Technique:

DonadonSDD replaceable GR graphite rupture discs are mounted on graphite or metal holders.
