Flame ArrestersThe Amal range of flame arresters provide explosionprotection during the storage and transportation offlammable gases or vapours.Amal flame arresters utilise a crimped metal element,which in section represents a matrix of triangularpassages or cells with guaranteed uniformity. Conclusiveproof exists that the crimped metal design is the mosteffective method of quenching potentially lethal ordestructive flames.The Amal crimped elements are stainless steel 316L asstandard and are regularly produced from manycommerciallyavailablematerialsincludingHastelloy®,nickel andMonel®.Our flamearresters arecertified to thehighest internationalstandard ISO 9001:2008 and the qualitysystem is also approvedin accordance with ATEXDirective 94/9/EC.In addition Amal flame arresters aredesigned, tested and certified to EN 12874 inaccordance with ATEX Directive 94/9/EC and havebeen tested and/or approved by: BS 7244:1990, USCG,IMO, FTZU, PTB, BAM, PROCHEM, CSA, HSE, INERIS,GOST-R and NEMCO.Amal flame arresters are also designed and certified tothe Pressure Equipment Directive 97/23/EC.Flame Arrester Design Connection GasType Application Size GroupsEnd-of-line Designed to stop unconfined Up to 600mm IIA, IIB, IIB 1/2/3, IIC to BS5501Deflagration deflagrations entering pipes and (24") Pt 1997 and EN50014causing explosions in storageand B, C, and D to thetanks or process plant.US National Electrical Code,N.B.
