INSTALLATION
 
Series 8350 Flame Arrestors should be mounted with the axis vertical and as close as possible to the potential source of ignition. Series 8360 Flame Arrestors have been designed for fitting to the down-turned end of free vent pipes.
 
CONSTRUCTION
 
Series 8350 Flame Arrestor consists of a tube bank made up of spirally wound alternate layers of flat and corrugated stainless steel sheets, built around a solid core. The tube bank offers a multiplicity of small holes parallel to the line of flow. The tube element is retained between two flanged end sections and contained within an outer shell. (See Fig.1) Flame Arrestor can be fitted with a weather hood. (See Fig.2)
 
FEATURES
 
Crimped Ribbon Element Design
The corrugated crimped ribbon design of the Series 8350 Flame Arrestor element enables it to be manufactured to very close tolerances and hence can be efficiently size selected to suit the widest range of applications and flow parameters. Pressure drop across the Flame Arrestor is very low and hence it is suitable for high gas flow rates.
OPTIONS AVAILABLE
Weather Hood
Weather hoods are available for fitting to all sizes of Flame Arrestors, for use where the arrestors are mounted in exposed position, e.g. on vessel roofs
SIZING AND SELECTION
Due to varying degrees of hazard, it is necessary to very carefully assess the type and capacity of Flame Arrestor required for safe operation. A detailed application form, as specified within this catalogue, should be completed for every proposed Flame Arrestor application and returned to us to assist in the correct sizing of the Flame Arrestor required to suit each application.
