Standards: GB\/T 12459-2025, GB\/T 13401-2025; export projects may comply with ASME B16.9-2024.
\nStructure\/Dimensions: Stainless steel concentric reducer; specify large-end \u00d7 small-end diameters, wall thicknesses for both ends, and length; ASME B16.9 covers NPS 1\/2\u201348 (DN15\u20131200), with wall thickness specified according to the connected piping Schedule (Sch) or design thickness.
\nConnection: Butt-weld; bevel type and root face dimensions to be confirmed based on welding procedures and project specifications.
\nMaterial: Stainless steel such as ASTM A403 WP304\/304L, WP316\/316L, etc.; manufacturing grade to be confirmed via the quality certificate; material grade, seamless\/welded type, heat treatment, and NDT requirements must be clearly specified at the time of inquiry.
\nPressure Rating: Butt-weld fittings generally do not carry a standalone “Class” rating; pressure-bearing capacity is determined by material, wall thickness, temperature, and applicable piping design codes.<\/p>\n
Ordering\/Acceptance: Confirm NPS\/DN, end diameters, wall thickness\/Sch, structural dimensions, seamless\/welded type, material grade, heat treatment, bevel details, and NDT requirements; verify pressure-bearing capacity based on material, wall thickness, temperature, and piping design codes.<\/p>","protected":false},"excerpt":{"rendered":"
These stainless steel butt-weld reducers feature aligned centerlines at both ends and are designed for coaxial diameter transitions in pipelines conveying corrosive or high-purity media. They minimize local flow resistance caused by abrupt changes in cross-section, making them suitable for vertical piping and pump discharge applications.<\/p>","protected":false},"featured_media":342,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[23],"product_tag":[],"class_list":["post-341","product","type-product","status-publish","has-post-thumbnail","product_cat-pipe-fittings","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/zetengflangefitting.com\/id\/wp-json\/wp\/v2\/product\/341","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zetengflangefitting.com\/id\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/zetengflangefitting.com\/id\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/id\/wp-json\/wp\/v2\/comments?post=341"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/id\/wp-json\/wp\/v2\/media\/342"}],"wp:attachment":[{"href":"https:\/\/zetengflangefitting.com\/id\/wp-json\/wp\/v2\/media?parent=341"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/id\/wp-json\/wp\/v2\/product_brand?post=341"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/id\/wp-json\/wp\/v2\/product_cat?post=341"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/id\/wp-json\/wp\/v2\/product_tag?post=341"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
