Reference Standards: Materials, manufacturing, inspection, and general tolerances comply with GB\/T 13401-2025 or ASME B16.9-2024; non-standard dimensions for reducing elbows must adhere to approved drawings.
\nConfiguration: 90\u00b0 or other angles; specify large-end \u00d7 small-end diameters, bending radius, wall thicknesses at both ends, and center-to-end dimensions.
\nConnection: Butt-weld; end bevels must match the connecting pipes.
\nMaterials: Carbon steel, stainless steel, or alloy steel; material specifications are selected based on the medium and design temperature\/pressure conditions.
\nPressure Rating: Requires verification of the reducing transition, wall thinning in the bend zone, and wall thicknesses at both ends; flange pressure classes cannot be directly applied.<\/p>\n
Ordering\/Acceptance: Confirm NPS\/DN, port diameters, wall thickness\/Schedule, dimensional details, seamless vs. welded construction, material grade, heat treatment, bevel configuration, and non-destructive testing (NDT) requirements; the pressure rating of butt-weld fittings is determined based on material, wall thickness, temperature, and piping design codes.<\/p>","protected":false},"excerpt":{"rendered":"
A special steel elbow that transitions the pipe diameter while changing the flow direction can eliminate the need for a reducer and one field weld. Due to the wide variety of size combinations, these are typically designed and manufactured according to approved drawings or manufacturer standards.<\/p>","protected":false},"featured_media":1603,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[30],"product_tag":[],"class_list":["post-1602","product","type-product","status-publish","has-post-thumbnail","product_cat-elbow","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/product\/1602","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/comments?post=1602"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/media\/1603"}],"wp:attachment":[{"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/media?parent=1602"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/product_brand?post=1602"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/product_cat?post=1602"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/product_tag?post=1602"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
