{"product_id":"blind-flange-3-class-900-raised-face-rf","title":"Blind Flange – 3\" Class 900 Raised Face (RF)","description":"\u003cp data-path-to-node=\"4\"\u003eThe 3\" Class 900 Raised Face (RF) Blind Flange is a massive, heavy-duty forged pipeline component engineered to safely and completely seal off the ends of piping systems, valves, or pressure vessel openings. Rated for Class 900 high-pressure applications, this 3-inch blind flange provides an impenetrable, permanent or temporary barrier in extreme industrial environments, ensuring absolute fluid containment and preventing hazardous leaks during system isolation, maintenance, or future pipeline expansion.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eUnlike slip-on or weld-neck flanges that allow fluid to pass through, a blind flange is a solid, unbored disc. When bolted onto a corresponding open flange, it creates a robust dead-end cap capable of withstanding immense internal line pressure and severe mechanical stress. This specific flange features a \u003cb data-path-to-node=\"5\" data-index-in-node=\"307\"\u003eRaised Face (RF)\u003c\/b\u003e profile. The sealing surface is slightly elevated above the bolting circle, allowing the flange to concentrate all the bolt load onto a smaller gasket area. This localized compression creates an exceptionally tight, high-integrity seal designed to contain high-pressure liquids and gases safely.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eManufactured from premium forged steel, this 3-inch 900# blind flange conforms precisely to ASME \/ ANSI B16.5 dimensional and metallurgical standards, ensuring seamless, leak-free compatibility with standardized industrial piping networks.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFeatures \u0026amp;
