Standards: GB\/T 9124.1-2019 (PN series) or GB\/T 9124.2-2019 (Class series); export projects may follow ASME B16.5-2025.
\nStructure: Includes Slip-On (SO) and Socket Weld (SW) types; verify flange bore, socket depth, and pipe outer diameter\/wall thickness respectively.
\nSize Range: ASME B16.5 generally covers NPS 1\/2\u201324; Class 2500 flanges apply up to NPS 12. Specific flange types may not cover all size-pressure combinations; consult the corresponding dimension 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 assembly with 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 each item against the corresponding standard dimension tables\u2014availability of all combinations cannot be assumed based solely on the standard’s overall scope.<\/p>","protected":false},"excerpt":{"rendered":"
This product display features a combination of slip-on flanges and socket-weld flanges. The former is suitable for standard low- to medium-pressure piping, while the latter is primarily used for small-bore, higher-pressure lines; selection should be based on bore size, pressure, temperature, and welding requirements.<\/p>","protected":false},"featured_media":327,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[15],"product_tag":[],"class_list":["post-326","product","type-product","status-publish","has-post-thumbnail","product_cat-uncategorized","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/product\/326","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=326"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/media\/327"}],"wp:attachment":[{"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/media?parent=326"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/product_brand?post=326"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/product_cat?post=326"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/zetengflangefitting.com\/pt\/wp-json\/wp\/v2\/product_tag?post=326"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
