Valves are technical accessories, but are often discussed as a separate category. In an open valve, fluid flows in the direction from higher pressure to lower pressure.<\/li>\n<li>Flange face is an important part of piping systems and mechanical equipment, where it is used to connect and fasten different parts together. Flanges are usually located at the ends of pipes or equipment and have holes for mounting with bolts. The main function of a flange is to create a tight connection between parts, allowing liquid or gas to flow through the system without leakage.<\/li>\n<\/ul>\n<p>Valves and flanges often rust due to electrochemical corrosion, a natural process that occurs when metal is exposed to moisture and oxygen.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_50 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\">M\u1ee5c l\u1ee5c<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\" role=\"button\"><label for=\"item-69d4558813e44\" aria-hidden=\"true\"><span style=\"display: flex;align-items: center;width: 35px;height: 30px;justify-content: center;direction:ltr;\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/label><input  type=\"checkbox\" id=\"item-69d4558813e44\"><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/nanotechvietnam.com\/en\/protection-of-surface-of-valve-flanger-by-s2s-corrosion-surface\/#Here_are_some_common_causes_of_rust\" title=\" Here are some common causes of rust:\"> Here are some common causes of rust:<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/nanotechvietnam.com\/en\/protection-of-surface-of-valve-flanger-by-s2s-corrosion-surface\/#Measures_to_protect_valves_and_flanges_from_rust\" title=\"Measures to protect valves and flanges from rust:\">Measures to protect valves and flanges from rust:<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/nanotechvietnam.com\/en\/protection-of-surface-of-valve-flanger-by-s2s-corrosion-surface\/#More_articles_for_reference\" title=\"More articles for reference:\">More articles for reference:<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/nanotechvietnam.com\/en\/protection-of-surface-of-valve-flanger-by-s2s-corrosion-surface\/#Contact_Info\" title=\"Contact Info:\">Contact Info:<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Here_are_some_common_causes_of_rust\"><\/span><strong> Here are some common causes of rust:<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Contact with water and oxygen: Metals in valves and flanges, especially steel, work in water and in the presence of oxygen (oxygen gas in the air).
