Elmac recommends:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>A first inspection 3 months following commissioning<\/li><li>An annual inspection is recommended as a minimum even for \u201cclean\u201d processes<\/li><li>An inspection if there is any evidence of an explosion<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Maintenance Guidelines:<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Check the arrester is correctly installed. In accordance with the flame arrester\u2019s operating conditions?<\/li><li>Ensure that no modifications have been made to the arrester without the manufacturer\u2019s written consent.<\/li><li>Damaged flame arresters must be taken out of operation and repaired or replaced.<\/li><li>Only the original manufacturer\u2019s spares can be used in flame arresters. If obsolete (ie pre-ATEX), the whole unit will need to be replaced.<\/li><li>Check flame arrester is secure within the pipework and not subject to undue strain.<\/li><li>Any openings (drain ports) are securely sealed with gas-tight fittings.<\/li><li>Tighten all fasteners to required torque.<\/li><li>Make accurate records of work carried out.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Common Maintenance Considerations Applicable to all Flame Arresters:<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Blockage of element with debris<\/li><li>Corrosion<\/li><li>Mechanical damage<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Flame Arrester Maintenance on Offshore Oil Rigs<\/h3>\n\n\n\n<p>Following discussions with a number of major offshore operators, Elmac has discovered that flame arresters \u2013 essential pieces of safety equipment \u2013 are often overlooked during planned maintenance and shutdown periods.<\/p>\n\n\n\n<p>Poorly maintained, corroded or damaged flame arresters may not be capable of providing the explosion protection they were designed for. Some of the problems we have seen include:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Stainless steel offshore flame arresters connected to carbon steel pipes with no insulation kits fitted \u2013 this can cause major galvanic corrosion.<\/li><li>Weather hoods missing from the arrester \u2013 the elements can end up badly damaged and slightly removed from the arrester body. If a flame arrester is damaged, its effectiveness to stop a flame will be impaired and it should be replaced.<\/li><li>Carbon steel flame arresters suffering from heavy corrosion. The element bolting can be fixed tight on the unit indicating that it will be overlooked during planned maintenance regimes.<\/li><li>Improvised flame arresters fitted to a vent line where the external section of the line heavy with surface scale. It goes without saying that only units approved to the latest standards can be used as flame arresters.<\/li><\/ul>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file alignleft\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/elmactechnologies.com\/wp-content\/uploads\/2021\/07\/Flame-Arrester-Maintenance-Guide-6.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"Contenu embarqu\u00e9 Embed of Flame Arrester Maintenance Guide..\"><\/object><a href=\"https:\/\/elmactechnologies.com\/wp-content\/uploads\/2021\/07\/Flame-Arrester-Maintenance-Guide-6.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Flame Arrester Maintenance Guide<\/a><a href=\"https:\/\/elmactechnologies.com\/wp-content\/uploads\/2021\/07\/Flame-Arrester-Maintenance-Guide-6.pdf\" class=\"wp-block-file__button\" download>Download<\/a><\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Chemical Safety Board (CSB) Recommends: Flame arresters require regular inspection and maintenance (cleaning) to maintain functionality.
