An explosion occurs when oxygen is mixed with combustible gases (acetylene, hydrogen, methane, etc.) in a certain proportion or when the pipe valve meets a sudden fire. The oxygen flow in the pipeline system change in the process of oxygen gas transportation, the European Industrial Gas Association (EIGA) developed the standard IGC Doc 13\/12E \u201cOxygen Pipeline and Piping Systems\u201d divided the Oxygen working conditions for \u201cimpact\u201d and \u201cnon-impact\u201d.

The material of the oxygen valve is limited to working pressure and flow rate to prevent the collision of particles and impurities in the pipeline. Therefore, the engineer should fully consider friction, static electricity, non-metal ignition, possible pollutants (carbon steel surface corrosion), and other factors when selecting an oxygen valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Oxygen Properties<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>The normal concentration in air is 21%<\/li>\r\n \t<li>Colorless, odorless, and tasteless.<\/li>\r\n \t<li>Cannot be detected by the human senses<\/li>\r\n \t<li>Not flammable but supports and accelerates combustion.<\/li>\r\n \t<li>Flammable materials, including some materials that are normally relatively<\/li>\r\n \t<li>Non-flammable in air, burn very rapidly in high oxygen concentrations.<\/li>\r\n \t<li>Three elements necessary for an oxygen fire are an ignition source, oxygen, and flammable material (fuel) \u2013 known as the \u201cfire triangle\u201d<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Material Used in Oxygen Valve<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nOrganic materials have ignition temperatures below those of metals.

The higher the concentration of oxygen, the greater the risk of combustion.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nLarson pointed out that, while certain precautions must be taken with liquid oxygen, it is even more important to be vigilant when working with it in the gaseous state.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Minimizing Risk<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nTo minimize the risk of fire, it is important to choose highly compatible materials for valves\u2014both metals and soft goods. It is also important to minimize ignition mechanisms. That can be done by minimizing soft goods and limiting the use of lubricants. It is also essential to utilizing best practices\u2014from design to manufacture, to getting the product to the site, to operating it.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>How to choose a valve used for oxygen?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nSome projects explicitly prohibit gate valves from being used in oxygen pipelines with design pressure greater than 0.1mpa. This is because the sealing surface of gate valves will be damaged by friction in relative motion (i.e. the opening\/closing of the valve), which causes small \u201ciron powder particles\u201d to fall off from the sealing surface and easily catch fire. Similarly, the oxygen line of another type of valve will also explode at the moment when the pressure difference between the two sides of the valve is large and the valve opens quickly.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":2,"filter":"raw"},{"term_id":3320,"name":"Oxygen Ball Valve","slug":"oxygen-ball-valve","term_group":0,"term_taxonomy_id":3320,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3319,"name":"Oxygen Globe Valve","slug":"oxygen-globe-valve","term_group":0,"term_taxonomy_id":3319,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3321,"name":"Oxygen Valve","slug":"oxygen-valve","term_group":0,"term_taxonomy_id":3321,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":2324,"name":"oxygen valves","slug":"oxygen-valves","term_group":0,"term_taxonomy_id":2324,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":30,"label":"oxygen"},{"value":3320,"label":"Oxygen Ball Valve"},{"value":3319,"label":"Oxygen Globe Valve"},{"value":3321,"label":"Oxygen Valve"},{"value":2324,"label":"oxygen valves"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v15.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Oxygen Ball Valve - Oxygen Globe Valve | Oxygen Valve - ZECO Valve<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/zecovalve.com\/pt\/oxygen-globe-valve-copper-alloy-globe-valve.html\" \/>\n<meta property=\"og:locale\" content=\"pt_PT\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Oxygen Ball Valve - Oxygen Globe Valve | Oxygen Valve - ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"Oxygen Ball Valve Under ambient conditions, oxygen is a colorless, odorless gas.
