Experts at EV Group China emphasize that these products are critical for mitigating axial, shear, and angular deformations caused by thermal expansion of piping systems or vibration loads from process equipment.<\/p>\n<h2>Technical Aspects of Standard Application<\/h2>\n<p>According to ASTM F1120 requirements, expansion joints must provide compensation capacity during temperature fluctuations, preventing the occurrence of critical stresses in load-bearing structures and connections. EV Group China specialists note that if the pipeline&#8217;s design geometry does not provide sufficient natural flexibility to absorb thermal deformations, the installation of bellows expansion joints is a mandatory engineering solution to ensure pipeline integrity.<\/p>\n<p>The standard allows for the implementation of additional design improvements that exceed the basic specification requirements if necessary to increase the reliability of the assembly under specific operating conditions.<\/p>\n<h2>Metric System and Standardization<\/h2>\n<p>In the text of the standard, inch-pound units are adopted as the primary units of measurement. Values in parentheses are provided solely for reference for conversion to the International System of Units (SI). When designing systems using EV Group China products, engineers are advised to rely on the primary specifications to avoid errors during conversion.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[112],"class_list":["post-69704","wiki","type-wiki","status-publish","hentry","wiki_category-astm"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69704","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\/69704\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69704"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69704"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
