The Shand & Jurs 94407 Horizontal Inline Deflagration Flame Arrester is designed to provide a positive flame stop in horizontal gas piping systems containing flammable vapors having a low flash point. The 94407 not only provides exceptional protection against propagation of flame from external source but also offers maximum flow capacity. It is specifically designed to prevent liquid accumulation in the tube bank assembly.
The tube bank design, consisting of a spiral-wound crimped ribbon around a solid core, maximizes flow capacity with minimum pressure drop. The standard flame arrester is Factory Mutual (FM) approved to meet the ATEX application requirements per EN 12874 and ISO 16852.
Periodic inspection, maintenance and replacement of the tube bank is easily accomplished by simply removing tie-bolts and minimally expanding the remaining jack screws. Once the upper and lower body sections are expanded, the tube bank is easily removed with the aid of a handle.
Standard body construction includes light weight cast aluminum, cast iron, ductile iron, cast steel, 304 stainless steel and 316 stainless steel body materials suitable for most environments. Tube bank is available in 304 stainless steel or 316 stainless steel as standard. A complete range of sizes from 2’’ [50 mm] through 12’’ [300 mm] are available with flat face or raised face flanges to match ANSI, EN1092 or JIS connections.
For highly corrosive applications, body and tube bank construction of Duplex SS, Hastelloy C, or Alloy 20 are available.
