Standards: GB\/T 12459-2025, GB\/T 13401-2025; ASME B16.9-2024 applies to export projects.
\nStructure\/Dimensions: Ellipsoidal butt-weld cap; specify nominal size, wall thickness, total depth, and end bevel; ASME B16.9 covers NPS 1\/2\u201348 (DN15\u20131200), with wall thickness specified according to the connected pipe’s 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: Carbon steel, stainless steel, or alloy steel; material grade, seamless\/welded construction, heat treatment, and non-destructive testing (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, nominal size, wall thickness\/Schedule, structural dimensions, seamless\/welded construction, material grade, heat treatment, bevel details, and NDT requirements; pressure-bearing capacity is verified based on material, wall thickness, temperature, and piping design codes.<\/p>","protected":false},"excerpt":{"rendered":"
Butt-weld pipe caps formed from seamless steel billets are used to permanently seal pipe ends and withstand internal pressure. Their seamless construction makes them suitable for process piping systems involving high temperatures, high pressures, or stringent leak control requirements.<\/p>","protected":false},"featured_media":1616,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[27],"product_tag":[],"class_list":["post-1615","product","type-product","status-publish","has-post-thumbnail","product_cat-pipe-cap","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/product\/1615","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/comments?post=1615"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/media\/1616"}],"wp:attachment":[{"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/media?parent=1615"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/product_brand?post=1615"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/product_cat?post=1615"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/product_tag?post=1615"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
