Standards: GB\/T 12459-2025, GB\/T 13401-2025; ASME B16.9-2024 applies to export projects.
\nStructure\/Dimensions: Stainless steel butt-weld pipe 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 piping Schedule (Sch) or design thickness.
\nConnection: Butt-weld; bevel type and root face dimensions are determined based on the welding procedure and project specifications.
\nMaterial: Stainless steel such as ASTM A403 WP304\/304L, WP316\/316L, etc.; material grade, seamless\/welded type, 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 have 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 type, 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":"
Stainless steel butt-weld pipe caps are used to seal the ends of pipelines conveying corrosive, clean, or high-purity media. When joined to the pipe via a full-penetration weld, they form a permanent pressure boundary, thereby reducing potential leak points associated with threaded or flanged connections.<\/p>","protected":false},"featured_media":375,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[27],"product_tag":[],"class_list":["post-374","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\/de\/wp-json\/wp\/v2\/product\/374","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=374"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/media\/375"}],"wp:attachment":[{"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/media?parent=374"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/product_brand?post=374"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/product_cat?post=374"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/de\/wp-json\/wp\/v2\/product_tag?post=374"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
