MARSTON Auxiliary Support Bursting Discs
In some applications, reverse pressures may exist greater than atmospheric pressure.

MARSTON Auxiliary Support Bursting Discs
Often an Opening Type Support alone will be sufficient. However, sometimes an additional Auxiliary Support is required.
This is designed to aid the opening support, whilst still maintaining a large free flow area. This type of support is often used in double disc assemblies, where a secondary disc is used to prevent an often variable reverse pressure from affecting the performance of the primary disc.
This is common when several bursting discs vent into a common line or flare stack. This type of support is generally re-useable, with only the opening support needing to be replaced.
