425 In-Line Deflagra on Flame Arrester Flanged It’s a Protec on System with ribbon coil deflagra on in-line flame arrester according with Direc ve 2014/34/EU and harmonized standard EN ISO 16852:2016. - Used for hydrocarbons or chemical pipeline. - Stage I vapor recovery compliant. - The Flame Arrester avoids propaga on of fire into the piping. - Surface Protec on System is for all ATEX zone (0, 1 and 2). The best performances allowed by the new regula on - Max distance from the poten al ignic on is 50 pipe’s diameter. - Max opera onal pressure (rela ve) is 0,1 bar. Gas & Vapor compa bility Inflammable gases and vapours classifica on is necessary to correct use of flame arrester. UE-Type Examina on Cer ficate EPT 18 ATEX 3053 X is for Explosion Group “IIB3” tested with Ethylene and compa ble for all gas with MESG > 0.65 mm for example: Ammonia, Industrial methane, Blas-furnace gas, Carbon monoxide, Propane, Butane, Pentane, Esane, Eptane, Iso-octane, Decane, Benzene, Xilene, Cyclohexane, Acetone, Ethyl-methyl-ketone, Methyl acetate, Ethyl acetate, Normal propyl acetate, Normal butyl acetate, Amyl acetate, Cloroethylene, Methanol, Ethanol, Iso Butanol, Normal Butanol, Amyl alcohol and Ethyl nitrite. Use only for gas or vapor with MESG > 0.65 mm. Burning ra ng BC=b, tBT=1 min. Max opera onal temperature 60°C. RIBBON COIL STAINLESS STEEL STAINLESS STEEL THREAD RING

PROTECTED SIDE SUPPORT SIDE SUPPORT SIDE PIPE SIZE FLOW l/min (230 mbar) Chemical Suitability - Standard model is for tradi onal fuel without addi ves. ON REQUEST: - “PTFE” coated model is for special fuel, non-aggresive solvents or chemical products.

Installa on - In-line flame arrester is for ver cal or horizontal installa on. - Protec on System is 2” bidirec onal and 3” 4” unidirec onal, safety is the supported side. - For correct installa on follow the Direc ves and product User Manual. - For the installa on of flame arresters it is necessary to strictly comply with the L/D ra o (pipe length/pipe diameter) and insure that the distance between poten al igni on sources and the flame arrester does not exceed the max ra o of 50 L/D that corresponds to explosion group IIA and IIB3 (NEC groups D to C) according to EN ISO 16852. - Explosion Group...
