Weld Neck Flange (WN)<\/h2>\n<p>Best for high-pressure and high-temperature. Long tapered hub, butt weld connection. Common in oil refineries, power plants.<\/p>\n<h2>2. Slip On Flange (SO)<\/h2>\n<p>Cost-effective for low-medium pressure. Slides over pipe, welded both sides. Water treatment, HVAC applications.<\/p>\n<h2>3. Blind Flange (BL)<\/h2>\n<p>Pipeline termination, pressure testing. Solid disk, no bore. Reusable for testing.<\/p>\n<h2>4. Socket Weld Flange (SW)<\/h2>\n<p>Small diameter high-pressure piping. Counterbore accepts pipe. Sizes 1\/2 to 2 inch.<\/p>\n<h2>5. Threaded Flange (TH)<\/h2>\n<p>No-welding applications. NPT\/BSP threads. Instrument connections, utility lines.<\/p>\n<h2>6. Lap Joint Flange (LJ)<\/h2>\n<p>Frequent disassembly. Used with stub end. Flange rotates for bolt alignment.<\/p>\n<h2>7. Ring Type Joint (RTJ)<\/h2>\n<p>Extreme high-pressure oil &amp; gas. Metal-to-metal seal. Class 900-2500.<\/p>\n<h2>8. Expander Flange<\/h2>\n<p>Connecting different pipe sizes. Larger flange than pipe OD.<\/p>\n<h2>9. Reducing Flange<\/h2>\n<p>Size reduction in piping. Smaller bore than flange OD.<\/p>\n<h2>10. Orifice Flange<\/h2>\n<p>Flow measurement. Orifice plate ready with pressure taps.<\/p>\n<h2>\u6807\u51c6<\/h2>\n<p>ASME B16.5 (North America), DIN EN 1092-1 (Europe), JIS B2220 (Japan), GOST 12820-80 (Russia\/CIS)<\/p>\n<h3>\ud83d\udcde \u7533\u8bf7\u68c0\u9a8c\u8bc1\u4e66<\/h3>\n<p><strong>WhatsApp\uff1a<\/strong>\u00a0+86-18658777855<\/p>\n<p><strong>\u7535\u5b50\u90ae\u4ef6\uff1a<\/strong>\u00a01007788887@qq.com<\/p>\n<p>\u2713 \u542b\u65e0\u635f\u68c0\u6d4b\u62a5\u544a\u7684 MTR \u2713 \u6b22\u8fce\u7b2c\u4e09\u65b9\u68c0\u9a8c<a href=\"https:\/\/www.720yun.com\/vr\/a6ajt7ynrw0\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-884\" src=\"http:\/\/www.songhaiflange.com\/wp-content\/uploads\/2026\/04\/4.webp\" alt=\"\" width=\"1290\" height=\"2317\" title=\"\" srcset=\"https:\/\/www.songhaiflange.com\/wp-content\/uploads\/2026\/04\/4.webp 1290w, https:\/\/www.songhaiflange.com\/wp-content\/uploads\/2026\/04\/4-167x300.webp 167w, https:\/\/www.songhaiflange.com\/wp-content\/uploads\/2026\/04\/4-570x1024.webp 570w, https:\/\/www.songhaiflange.com\/wp-content\/uploads\/2026\/04\/4-768x1379.webp 768w, https:\/\/www.songhaiflange.com\/wp-content\/uploads\/2026\/04\/4-855x1536.webp 855w, https:\/\/www.songhaiflange.com\/wp-content\/uploads\/2026\/04\/4-1140x2048.webp 1140w, https:\/\/www.songhaiflange.com\/wp-content\/uploads\/2026\/04\/4-7x12.webp 7w, https:\/\/www.songhaiflange.com\/wp-content\/uploads\/2026\/04\/4-416x747.webp 416w\" sizes=\"auto, (max-width: 1290px) 100vw, 1290px\" \/><\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>\u6cd5\u5170\u7c7b\u578b\u5927\u5168\uff1a\u710a\u9888\u3001\u6ed1\u5957\u3001\u76f2\u677f\u3001\u627f\u63d2\u710a\u3001\u87ba\u7eb9\u3001\u642d\u63a5\u3001RTJ\u3002\u6839\u636e\u5e94\u7528\u8fdb\u884c\u9009\u62e9\u3002<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-881","post","type-post","status-publish","format-standard","hentry","category-blog"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.songhaiflange.com\/zh\/wp-json\/wp\/v2\/posts\/881","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.songhaiflange.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.songhaiflange.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.songhaiflange.com\/zh\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.songhaiflange.com\/zh\/wp-json\/wp\/v2\/comments?post=881"}],"version-history":[{"count":3,"href":"https:\/\/www.songhaiflange.com\/zh\/wp-json\/wp\/v2\/posts\/881\/revisions"}],"predecessor-version":[{"id":888,"href":"https:\/\/www.songhaiflange.com\/zh\/wp-json\/wp\/v2\/posts\/881\/revisions\/888"}],"wp:attachment":[{"href":"https:\/\/www.songhaiflange.com\/zh\/wp-json\/wp\/v2\/media?parent=881"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.songhaiflange.com\/zh\/wp-json\/wp\/v2\/categories?post=881"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.songhaiflange.com\/zh\/wp-json\/wp\/v2\/tags?post=881"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
