It is a strong oxidizing and combustible substance and can combine with most elements to form oxides except for gold, silver, and inert gases such as helium, neon, argon, and krypton. 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 \u201cimpact \u201d is a dangerous occasion because it is easy to stimulate energy, causing combustion and explosion. The oxygen valve is the typical \u201cimpact occasion\u201d.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nOxygen valve is a type of special valve designed for an oxygen pipeline and has been widely used in metallurgy, petroleum, chemical, and other industries involving oxygen. 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 use of organic materials in contact with oxygen should be avoided, particularly when the material is directly in the flow stream. When an organic material must be used for parts such as valve seats, diaphragms, or packing, it is preferable to select a material with the highest ignition temperature, the lowest specific heat, and the necessary mechanical properties.\r\nLubricants and sealing compounds should be used only if they are suitable for oxygen service and then used sparingly.

However, if there is a combustion event, high-oxygen content means that combustible materials do burn much faster. Particle impact, rapid pressurization, or compression of materials can result in heating that could cause combustion.

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":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":2325,"label":"bronze globe valve"},{"value":2285,"label":"flange globe valve"},{"value":2326,"label":"forged steel gate valve"},{"value":2281,"label":"forged steel globe valve"},{"value":30,"label":"oxygen"},{"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>Iron Making Engineering of Huoqiu Iron Mine Deep Project - 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\/es\/iron-making-engineering-of-huoqiu-iron-mine-deep-project.html\" \/>\n<meta property=\"og:locale\" content=\"es_ES\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Iron Making Engineering of Huoqiu Iron Mine Deep Project - ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"The total investment of the 10 million tons\/year steel project in Huoqiu is expected to be 30 billion yuan.
