When a part of line or piece of equipment needs to be inspected or taken out of operation, a spectacle blind is a safety device used to isolate the section of line or piece of equipment. The blind differs from a valve in that it is a long-term or permanent isolation device. A spectacle blind is made from a single piece of metal that is cut to the pipe size, squeezed between two pipe flanges, and attached with an extra gasket. According to the piping class and size blind that are being used, the bolts will also need to be stretched. Line pressure and pipe size are used to specify the thickness of the spectacle blind.
