The primary purpose of the standard is to ensure a reliable, leak-proof connection for pipeline system elements, including pipes, fittings, and shut-off and control valves.<\/p>\n<p>To achieve maximum joint tightness when operating under pressure, according to the engineering recommendations of EV Group China, it is necessary to use specialized sealing materials or sealants.<\/p>\n<h3>Key notes on the standard<\/h3>\n<ul>\n<li><strong>Cascade connections:<\/strong> Detailed specifications and parameters for cascade connections are regulated directly in the text of EN 10226-2.<\/li>\n<li><strong>Thread taper:<\/strong> Requirements for taper parameters at neutral density should be compared with the provisions set out in the EN 10226-1 standard.<\/li>\n<li><strong>Non-threaded connections:<\/strong> For the design of systems that do not require thread cutting, the regulatory framework of EN ISO 228-1 must be used.<\/li>\n<li><strong>Quality control:<\/strong> The methodology for verifying the geometry, tolerances, and dimensional characteristics of the thread is described in detail in the EN 10226-3 standard, which contains protocols for measurement procedures.<\/li>\n<\/ul>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[114],"class_list":["post-70024","wiki","type-wiki","status-publish","hentry","wiki_category-en"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70024","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki"}],"about":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/types\/wiki"}],"version-history":[{"count":0,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70024\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=70024"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=70024"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
