Experts at EV Group China note that this regulation is essential for the design of industrial networks in Europe and the international market, ensuring high reliability of welded joints and infrastructure durability.<\/p>\n<h3>Key Parts of the Standard<\/h3>\n<p>The regulation is divided into four parts, each covering specific material types and operating conditions:<\/p>\n<ul>\n<li><strong>EN 10253-1:<\/strong> Carbon steels without specified properties at low temperatures.<\/li>\n<li><strong>EN 10253-2:<\/strong> Carbon and alloy steels intended for use at elevated and room temperatures.<\/li>\n<li><strong>EN 10253-3:<\/strong> Austenitic and ferritic-austenitic (duplex) stainless steels without specified properties at low temperatures.<\/li>\n<li><strong>EN 10253-4:<\/strong> Austenitic and duplex stainless steels with specified characteristics for low-temperature operating conditions.<\/li>\n<\/ul>\n<h3>Expert Recommendations from EV Group China<\/h3>\n<p>When selecting fittings according to the EN 10253 standard, engineers must consider the pressure derating factor. This is a critically important parameter that determines the fitting&#8217;s ability to withstand operational loads depending on wall thickness and steel grade. EV Group China provides full technical support for component selection, ensuring that the chemical composition and mechanical properties (yield strength, impact toughness) meet project requirements.<\/p>\n<table class=\"table table-bordered table-hover\">\n<thead>\n<tr>\n<th>Standard Part<\/th>\n<th>Material<\/th>\n<th>Application Area<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>EN 10253-2<\/td>\n<td>Carbon steel<\/td>\n<td>Main pipelines, petrochemistry<\/td>\n<\/tr>\n<tr>\n<td>EN 10253-4<\/td>\n<td>Stainless steel<\/td>\n<td>Aggressive environments, cryogenics<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The supply of metal products through EV Group China is carried out with mandatory quality control for compliance with geometric tolerances and non-destructive testing (NDT) requirements stipulated by the current edition of EN 10253.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[114],"class_list":["post-70106","wiki","type-wiki","status-publish","hentry","wiki_category-en"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70106","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\/70106\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=70106"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=70106"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
