Leakage control is a fundamental requirement in mechanical and process engineering. Whether in chemical plants, oil and gas pipelines, semiconductor tools, or high-pressure hydraulic systems, unintended leakage can lead to equipment failure, safety hazards, environmental contamination, and regulatory non-compliance. To manage this risk, international standards such as ISO and ANSI define leakage classes that quantify […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[28],"tags":[624,59,65,619,585,578,628,620,625,623,626,581,53,627,579,621,57,66,574,559],"class_list":["post-1649","post","type-post","status-publish","format-standard","hentry","category-technical-guides","tag-ansi-leakage-classes","tag-backup-rings","tag-dynamic-seals","tag-elastomer-seals","tag-ffkm","tag-fkm","tag-helium-leak-testing","tag-high-pressure-sealing","tag-iso-leakage-classes","tag-leakage-control","tag-lip-seals","tag-metal-seals","tag-o-rings","tag-pressure-decay-testing","tag-ptfe","tag-reliability-engineering","tag-seal-selection","tag-static-seals","tag-surface-roughness","tag-tolerance-control"],"_links":{"self":[{"href":"https:\/\/www.wonzh.com\/vi\/wp-json\/wp\/v2\/posts\/1649","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wonzh.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.wonzh.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.wonzh.com\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wonzh.com\/vi\/wp-json\/wp\/v2\/comments?post=1649"}],"version-history":[{"count":1,"href":"https:\/\/www.wonzh.com\/vi\/wp-json\/wp\/v2\/posts\/1649\/revisions"}],"predecessor-version":[{"id":1650,"href":"https:\/\/www.wonzh.com\/vi\/wp-json\/wp\/v2\/posts\/1649\/revisions\/1650"}],"wp:attachment":[{"href":"https:\/\/www.wonzh.com\/vi\/wp-json\/wp\/v2\/media?parent=1649"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wonzh.com\/vi\/wp-json\/wp\/v2\/categories?post=1649"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wonzh.com\/vi\/wp-json\/wp\/v2\/tags?post=1649"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
