Amal metal flame arresters are safety devices designed to stop the propagation or spread of flames through flammable gases or vapour mixtures in pipelines. They prevent flames from entering or leaving the plant and can confine flame propagation to within certain equipment.

MARSTON
A complete range of non-reclosing pressure relief devices, from simple conventional designs through composite assemblies to top-of-the-range reverse buckling discs.
The Marston range of bursting discs provides reliable and cost-effective pressure protection for any pressurized system, particularly in chemical, oil and gas, pharmaceutical, plastics and rubber industries. With a broad range of material options and accessories, these can be used as primary safety device to give almost instantaneous pressure protection, in parallel with other pressure safety devices, or also to protect a safety valve against corrosive or viscous process media.
Flat
-
For low pressures
-
Metals but mainly PTFE and PFA
-
Usually non-fragmenting
depending on material
Reverse Buckling
-
Dome directed towards process
-
Works in compression
-
Usually non-fragmenting
-
Accepts lower operating range
Forward Acting
‘Conventional’
-
The ‘original’ disc
-
Burst on tension
-
Fragmentation
-
Very high pressures possible
