Reference Standards: ASME B16.9 for butt-weld lap joint stub ends; MSS SP-43-2026 for low-pressure, corrosion-resistant, thin-wall systems.
\nConfiguration: Long or short pattern stub ends; specifications include NPS\/DN, wall thickness, barrel length, lap outside diameter, lap thickness, and fillet radius.
\nConnection: Butt-weld at the barrel end; lap end mates with a lap joint flange and gasket.
\nMaterials: Carbon steel, stainless steel, or alloy steel; lap material must be compatible with the process medium.
\nPressure Rating: Determined by the combination of fitting wall thickness, material, lap joint flange, and gasket system.<\/p>\n
Ordering\/Acceptance: Confirm pattern (long\/short), nominal size, wall thickness, barrel length, lap dimensions, fillet radius, and material; ensure compatibility with the mating lap joint flange, gasket, and bolting system.<\/p>","protected":false},"excerpt":{"rendered":"
A lap-joint stub end is used in conjunction with a loose-fitting (lap-joint) flange; the welded end connects to the piping, while the flanged end provides the sealing surface. The loose flange can rotate freely to facilitate bolt-hole alignment. This configuration is suitable for systems requiring frequent disassembly or the use of corrosion-resistant piping materials.<\/p>","protected":false},"featured_media":369,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[25],"product_tag":[],"class_list":["post-367","product","type-product","status-publish","has-post-thumbnail","product_cat-stub-end","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/product\/367","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=367"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/media\/369"}],"wp:attachment":[{"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/media?parent=367"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/product_brand?post=367"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/product_cat?post=367"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/ar\/wp-json\/wp\/v2\/product_tag?post=367"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
