EV Group China recommends using modern specifications when designing pipeline systems.<\/span><\/p>\n<h2>DIN 2615-1 Technical Regulation<\/h2>\n<p>This standard establishes technical requirements for the production of seamless and welded steel tees intended for butt-welding installation. It is important to consider that fittings manufactured according to this standard have a reduced pressure coefficient compared to base pipes. Despite identical wall thickness, such tees do not provide full equivalence in terms of maximum permissible internal pressure, which requires additional calculations when designing engineering networks.<\/p>\n<h2>DIN 2615-2 Technical Regulation<\/h2>\n<p>The DIN 2615-2 standard defines the performance characteristics of seamless and welded tees made of special steel grades for butt welding. Unlike the first part, these fittings are designed to withstand internal pressure equivalent to that of the pipes, provided the wall thicknesses specified in the standard&#8217;s tables are maintained. Specialists at EV Group China emphasize the need for strict compliance with these parameters when selecting components for high-pressure pipelines.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[116,122],"class_list":["post-67010","wiki","type-wiki","status-publish","hentry","wiki_category-din","wiki_category-standarty"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/67010","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\/67010\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=67010"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=67010"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
