The Shand & Jurs Flame Arresters are designed to provide a positive flame stop on low pressure tanks, storage tanks and anaerobic digesters containing flammable liquids, solvents or gases having a low flash point. The 94306 not only provides exceptional protection against fire from external ignition, but also offers maximum flow capacity.
Shand & Jurs Flame Arresters are generally installed with pressure-vacuum vents, or in-line free vent to atmosphere. The tube bank design consisting of a spiral-wound crimped ribbon around a solid core, maximize flow capacity with minimum pressure drop. This unique design meets FM Factory Mutual approval for all sizes and material options.
Standard construction includes light weight cast aluminum, cast iron, cast steel, 304 stainless steel and 316 stainless steel body materials suitable for most environments. Tube bank is available in aluminum, 304 stainless steel and 316 stainless steel as standard. For highly corrosive and severe conditions, special materials and coatings are available.
Available with flat face flanges for aluminum or raised face flanges for cast steel and stainless steel to match ANSI, EN1092-1, or JIS 10K specifications.
Periodic inspection, maintenance and replacement of the tube bank is easily accomplished by simply removing tie-bolts and expanding the remaining jack screws. Once the upper and lower body sections are expanded, the tube bank and shell are easily removed with the aid of a handle.
