The connection system, consisting of welding collars (DIN 86037-2) and loose flanges (DIN 86037-3), is an industry standard for the reliable installation of copper-nickel alloy pipelines.<\/p>\n<h3>Operational parameters and application<\/h3>\n<p>The components are designed for operation in marine environments at operating temperatures up to 120\u00b0C. Permissible working pressure ratings are regulated by design data for specific pipeline configurations made of CuNi10Fe1.6Mn alloy and correspond to the nominal characteristics of the flange connection.<\/p>\n<h3>Welding collars according to DIN 86037-2<\/h3>\n<p>Welding collars are designed for integration into ship piping systems. They ensure connection tightness when paired with loose flanges and are ideal for the installation of copper-nickel pipes manufactured in accordance with DIN 86018 and DIN 86019. The use of these elements allows for the compensation of thermal expansion and simplifies the assembly\/disassembly process of pipelines.<\/p>\n<h3>Loose flanges according to DIN 86037-3<\/h3>\n<p>Loose flanges serve as the mating part of the connection. Their design allows for precise positioning of bolt holes, which is critical when installing complex engineering systems on ships. EV Group China supplies these products for the professional outfitting of ship piping, guaranteeing full compliance of geometric parameters with DIN specifications.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[116,122],"class_list":["post-66916","wiki","type-wiki","status-publish","hentry","wiki_category-din","wiki_category-standarty"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/66916","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\/66916\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=66916"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=66916"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
