The pipe is inserted into a recessed socket area and fillet welded to the flange hub, creating a strong, leak-proof connection.<\/p>\n<h3>Key Features<\/h3>\n<ul>\n<li>Socket bore matches pipe outer diameter for precise fit<\/li>\n<li>Fillet weld provides strong mechanical connection<\/li>\n<li>Internal crevice minimized for better flow characteristics<\/li>\n<li>Available in raised face (RF) or ring type joint (RTJ)<\/li>\n<\/ul>\n<h3>\u041f\u0440\u0435\u0438\u043c\u0443\u0449\u0435\u0441\u0442\u0432\u0430<\/h3>\n<ol>\n<li>Excellent for high-pressure applications<\/li>\n<li>Better fatigue strength than slip-on flanges<\/li>\n<li>No beveling required for welding<\/li>\n<li>Good flow characteristics with proper gap<\/li>\n<li>Cost-effective for small diameter piping<\/li>\n<\/ol>\n<h3>\u041f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u044f<\/h3>\n<ul>\n<li>High-pressure steam lines (NPS 2 and below)<\/li>\n<li>Hydraulic systems<\/li>\n<li>Chemical injection lines<\/li>\n<li>Instrument tubing connections<\/li>\n<li>High-pressure process piping<\/li>\n<\/ul>\n<h3>Installation Guidelines<\/h3>\n<p>Important: Leave a 1.6mm (1\/16 inch) gap between pipe end and socket bottom to allow for thermal expansion and reduce weld stress.<\/p>\n<h3>Standards and Specifications<\/h3>\n<ul>\n<li>ASME B16.5: NPS 1\/2 to 3, Class 150-2500<\/li>\n<li>ASME B16.11: Forged fittings, socket weld and threaded<\/li>\n<li>EN 1092-1: European standard socket weld flanges<\/li>\n<\/ul>\n<h3>Material Options<\/h3>\n<ul>\n<li>Stainless Steel: 304\/304L, 316\/316L, 321, 347<\/li>\n<li>Carbon Steel: ASTM A105, A350 LF2<\/li>\n<li>Alloy Steel: F11, F22, F91<\/li>\n<li>Duplex Steel: 2205, 2507<\/li>\n<\/ul>\n<p>Socket weld flanges are the ideal choice for small-bore, high-pressure piping systems where leak-tight integrity is critical.<\/p>\n<p><strong>WhatsApp:<\/strong>\u00a0+86-18658777855<br
