This provides an extinguishing barrier to the ignited vapor mixture.
The flame arresters have specifically designed heat transfer characteristics for slow-moving flames and low to medium pressure fronts (low to medium deflagration).
Inline flame arresters can be installed either vertically or horizontally within a designated distance from the potential ignition extras.
The standard flame cell is suitable for NEC group D or IEA IIA gases. Cells for other gas groups are available as additional extras.
The standard design shall be used up to an operating temperature of + 60 deg C / 140 deg F and operating pressure up to 1.1 bar abs from size ½” / 15A to 12” / DN 300. Upon request, it can be obtained for higher pressure and higher temperature with special approval.
The flame arresters are available with either aluminum, nodular iron, cast steel, 304SS, 316SS, and 316LSS housings. Iron and steel housings are supplied epoxy coated.
Sizes range from 15mm to 600mm and are available upon request. Standard flanges are ANSI 150lb and other connections and sizes are available upon request.
Periodic inspection and maintenance are required. The cell assembly can be removed for cleaning purposes. Cleaning can be accomplished by dipping the entire cell assembly into an appropriate solvent. Care should be taken not to damage the cell openings as such deformations hamper the flow through the cell. The gaskets should be inspected and replaced if necessary.
