Shand & Jurs Models 94311, 9312, 9313 and 94314 are detonation flame arresters that provide protection against flame propagation through piping runs and vapour recovery systems, while allowing maximum flow efficiencies. This design quenches a flame front approaching from either direction, even if it has transitioned to a detonation.
The 94311-94314 arresters contain a detonation while retaining the integrity of both the arresting element and the housing. This is ensured by the design of the passages in the tube bank and the detonation resistant construction.
Standard construction of the housing is available in Carbon Steel or 316 Stainless Steel. The tube bank is Stainless Steel throughout. Special construction materials to withstand the corrosive actions of some vapors and atmospheric conditions are available upon request.
Because of the severe service conditions that the Detonation Flame Arrester encounters, all construction welding is performed in accordance with ASME Boiler and Pressure Vessel Code Section Vlll and IX. Class 150lb. hydrostatically tested at 425 psig. Class 300lb. hydrostatically tested at 750 psig.
These models are available in a range of sizes from 2" through 24". Additional sizes available upon request. Standard connections are ANSI 150lb. or 300lb. Class raised face flanges.
