Handling Liquefied Natural Gas (LNG) at a punishing -162\u00b0C (-260\u00b0F) demands extreme metallurgical rigor from every piping component. At these severe cryogenic temperatures, standard carbon steels undergo a fatal ductile-to-brittle transition, effectively shattering like glass under operational pressure. This is precisely why specifying a seamless nickel alloy pipe for LNG applications isn’t just an engineering […]<\/p>\n","protected":false},"author":1,"featured_media":3925,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-3923","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/posts\/3923","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/comments?post=3923"}],"version-history":[{"count":2,"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/posts\/3923\/revisions"}],"predecessor-version":[{"id":3927,"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/posts\/3923\/revisions\/3927"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/media\/3925"}],"wp:attachment":[{"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/media?parent=3923"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/categories?post=3923"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.nickelcasting.com\/ko\/wp-json\/wp\/v2\/tags?post=3923"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
