It is designed to comply with maritime safety standards and is essential for acetylene and oxygen gas systems. Maritime authorities, such as the Norwegian Maritime Directorate, mandate the installation of flashback arrestors to prevent accidents caused by flashbacks, which can result from improper maintenance or misuse of gas welding equipment.<\/p>\n<p>Flashbacks typically stop at a well-designed torch, identified only by a popping sound. However, faulty handling, maintenance, or incorrect gas pressure settings may lead to penetrating flashbacks. In such cases, the flame may travel through hoses, pass the regulator, and potentially reach the cylinder.<\/p>\n<p>The inline acetylene flashback arrestor acts as a critical safety barrier, preventing flashback or decomposition from advancing to the high-pressure areas of the gas distribution system. Inline oxygen flashback arrestors are also available as accessories.<\/p>\n<h4>Key Safety Features<\/h4>\n<ul>\n<li>Non-Return Valve: Prevents reverse gas flow, avoiding gas mixtures from reaching pipelines or cylinders.<\/li>\n<li>Flame Arrestor: Quenches the flame front from flashbacks or burnbacks.<\/li>\n<li>Temperature-Activated Cut-Off: Stops gas supply in case of fire if the temperature rises to approximately 100\u00b0C.<\/li>\n<li>Pressure-Activated Cut-Off: Halts gas supply after a flashback, triggered by the pressure shock in front of the flashback.<\/li>\n<li>Marine flashback arrestors are built to conform to EN 730\/ISO 5175 standards and are certified by BAM with Certification No.: ZBF\/009\/12.<\/li>\n<\/ul>\n<h4>Safety Recommendations<\/h4>\n<ul>\n<li>Annual Testing: Regular testing of flashback arrestors is highly recommended to ensure functionality.<\/li>\n<li>Five-Year Replacement: Replace flashback arrestors every five years to maintain safety and compliance. For vessels under OCIMF SIRE and RIGHTSHIP RISQ, replacement is mandatory within five years from the manufacturing date. The manufacturing date is marked on the flashback arrestor for easy reference.<\/li>\n<\/ul>\n<h4>Features<\/h4>\n<ul>\n<li>Flame arrestor.<\/li>\n<li>Thermal valve.<\/li>\n<li>Non-return valve.<\/li>\n<li>Inline flashback arrestor for added protection.<\/li>\n<\/ul>\n<h4>Benefits<\/h4>\n<ul>\n<li>Stops the pressure front and flame front effectively.<\/li>\n<li>Prevents gas from supporting fire.<\/li>\n<li>Stops gas from backfeeding into the system.<\/li>\n<\/ul>\n<p>The Marine flashback arrestor ensures reliable and compliant protection for acetylene and oxygen gas systems, enhancing safety and operational security in maritime applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<h2><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-87408\" src=\"https:\/\/roussakis.com.gr\/wp-content\/uploads\/2023\/04\/unitor-logo3.png\" alt=\"\" width=\"137\" height=\"40\" \/><\/h2>\n<p>Code: <a href=\"https:\/\/www.wilhelmsen.com\/product-catalogue\/products\/gases-refrigerants-and-cylinders\/gas-distribution-system\/low-pressure-components\/flashback-arrestor-ac-8510\/?epslanguage=en\" target=\"_blank\" rel=\"noopener\">585372 85-10 AC<\/a> | <a href=\"https:\/\/www.wilhelmsen.com\/product-catalogue\/products\/gases-refrigerants-and-cylinders\/gas-distribution-system\/low-pressure-components\/flashback-arrestor-85-10-ox-for-gas-central-reg\/?epslanguage=en\" target=\"_blank\" rel=\"noopener\">682427 85-10 OX<\/a><\/p>\n<p><a href=\"https:\/\/roussakis.com.gr\/wp-content\/uploads\/DG91N-Flashback-arrestor.pdf\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-98477\" src=\"https:\/\/roussakis.com.gr\/wp-content\/uploads\/pdficon.png\" alt=\"\" width=\"50\" height=\"50\" \/><\/a><\/p>\n","protected":false},"featured_media":92796,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"pwb-brand":[595],"product_cat":[4068,974,2973],"product_tag":[3350],"class_list":{"0":"post-103745","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"pwb-brand-ibeda-en","7":"product_cat-ac-ox-gas-distribution-system-en","8":"product_cat-marine-oxygen-equipment-en","9":"product_cat-safety-valves-flame-arrestors-oxygen-tools","10":"product_tag-valvides-asfaleias-en","12":"first","13":"instock","14":"taxable","15":"shipping-taxable","16":"purchasable","17":"product-type-variable"},"composite_virtual":false,"composite_layout":"","composite_add_to_cart_form_location":"","composite_editable_in_cart":false,"composite_sold_individually_context":"","composite_shop_price_calc":"","composite_components":[],"composite_scenarios":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 -
