Spectacle blind flanges are forged products that won’t blind pipelines. These devices are cost-effective alternatives to isolation valves. A spectacle blind combines, in one single product, a flange spade and a hoop spacer. Spectacle Blind Flange usually used on large diameter pipelines, one end occupied space-maintaining pipeline flow, change to the opposite end of the blind plate to cut off the line, consistent with ANSI B16.48 American Standard. Spectacle Flanges are generally applied to permanently separate pipe systems, or simply to attach with one another. A spectacle blind Flange is machined from one piece of metal that’s cut to match the pipe size, fit between two pipe flanges, and requires an extra gasket when it’s installed. The bolts will be got to be lengthened depending on what piping class and size blind is used. The thickness of the spectacle blind Flange is specified based on the line pressure and pipe size. One end of the blind will have an opening to permit flow through the pipe during operation and therefore the other end is solid to block flow. We supply Spectacle Blind Flange with a range of products worldwide.
