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.  Oxygen 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.  Oxygen Properties  The normal concentration in air is 21% Colorless, odorless, and tasteless. Cannot be detected by the human senses Not flammable but supports and accelerates combustion. Flammable materials, including some materials that are normally relatively Non-flammable in air, burn very rapidly in high oxygen concentrations. Three elements necessary for an oxygen fire are an ignition source, oxygen, and flammable material (fuel) \u2013 known as the \u201cfire triangle\u201d  Material Used in Oxygen Valve  Organic 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. Lubricants and sealing compounds should be used only if they are suitable for oxygen service and then used sparingly. Ordinary petroleum lubricants are not satisfactory and are particularly hazardous because of their high heat of combustion and high rate of reaction. The approximate ignition temperatures in 138 bar (2000 psig) oxygen for a few organic materials are shown in table 1. Table 1. Typical Ignition Temperatures    MATERIAL TYPICAL IGNITION TEMPERATURE IN 138 BAR (2000 PSIG) OXYGEN  PTFE and PCTFE 468  70% Bronze\u2010filled PTFE 468  Fluoroelastomer 316  Nylon 210  Polyethylene 182  Chloroprene and Nitrile 149    Metals  The selection of metals should be based on their resistance to ignition and rate of reaction. Following is a comparison of these two properties for some commonly used valve materials.  Resistance to Ignition in Oxygen  Materials are listed in order from hardest to ignite to easiest to ignite.  Copper, copper alloys, and nickel\u2010copper alloys \u2010\u2010 most resistant Stainless steel (300 series) Carbon steel Aluminum \u2010\u2010 least resistant  Rate of Reaction  Materials are listed in order from the slowest rate of combustion to the most rapid rate of combustion.  Copper, copper alloys, and nickel\u2010copper alloys \u2010\u2010 do not normally propagate combustion Carbon steel Stainless steel (300 series) Aluminum \u2010\u2010 burns very rapidly  Note that stainless steel, once ignited, burns more rapidly than carbon steel. Nevertheless, the austenitic grades (300 series) of stainless steel are considered to be much better than carbon steel because of their high resistance to ignition.  GET OXYGEN VALVE PRICE  How Dangerous is Oxygen  Oxygen is not combustible alone. 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. Contamination and mechanical energy such as friction can also cause ignition and result in fast, hot fires when more oxygen is present. The higher the concentration of oxygen, the greater the risk of combustion.  Larson 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.  Minimizing Risk  To 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.  How to choose a valve used for oxygen?  Some 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.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/es\/tag\/oxygen\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebSite\",\"@id\":\"https:\/\/zecovalve.com\/#website\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"ZECO Valve\",\"description\":\"Industrial Ball Valve, Gate Valve and Globe Valve Manufacturer\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":\"https:\/\/zecovalve.com\/?s={search_term_string}\",\"query-input\":\"required name=search_term_string\"}],\"inLanguage\":\"es\"},{\"@type\":\"CollectionPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/oxygen#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/oxygen\",\"name\":\"Oxygen Ball Valve - Choose Right Oxygen Valve | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/oxygen#breadcrumb\"},\"inLanguage\":\"es\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/oxygen\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/oxygen#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"Home\"}},{\"@type\":\"ListItem\",\"position\":2,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/oxygen\",\"url\":\"https:\/\/zecovalve.com\/tag\/oxygen\",\"name\":\"oxygen\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/tags\/30","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/posts?tags=30"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
