Standards: GB\/T 9124.1-2019 (PN series) or GB\/T 9124.2-2019 (Class series); export projects may comply with ASME B16.5-2025.
\nStructure: Socket Weld (SW) flange; orders must match the pipe’s outside diameter and wall thickness, and verify the socket bore depth.
\nSize Range: The ASME B16.5 standard generally covers NPS 1\/2\u201324; Class 2500 flanges apply up to NPS 12. Specific flange types do not necessarily cover all size-pressure combinations; refer to the corresponding dimensional tables.
\nPressure Ratings: Class 150, 300, 400, 600, 900, 1500, 2500, or selected according to the corresponding PN series; allowable pressure-temperature ratings vary based on material group and operating temperature.
\nMaterials\/Facing: Common materials include ASTM A105, A182 F304\/F316, etc.; facing types (RF, FF, RTJ, etc.) must be confirmed as a complete set alongside gaskets, bolts, and mating flanges.<\/p>\n
Ordering\/Acceptance: Confirm flange type, DN\/NPS, PN\/Class, material group, facing type, pipe wall thickness\/bore, and bolting\/gasket systems; verify against the corresponding standard dimensional tables item by item\u2014availability of all combinations cannot be assumed based solely on the standard’s overall scope.<\/p>","protected":false},"excerpt":{"rendered":"
For a flange where the pipe end is inserted into the socket and secured by an external fillet weld, the inner bore forms a relatively smooth flow path. It is primarily used for small-diameter, high-pressure pipelines; a specified clearance must be maintained between the pipe end and the bottom of the socket during installation.<\/p>","protected":false},"featured_media":321,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[22],"product_tag":[],"class_list":["post-320","product","type-product","status-publish","has-post-thumbnail","product_cat-flange","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/product\/320","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/comments?post=320"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/media\/321"}],"wp:attachment":[{"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/media?parent=320"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/product_brand?post=320"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/product_cat?post=320"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/product_tag?post=320"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
