Spectacle Blinds are basic safety devices that are fitted between two pipe flanges. During normal operation, the open end serves as a spacer to facilitate continuous flow. The blind end is rotated into place between the flanges to halt the flow in the pipeline. Spectacle Blinds are used in systems that must be separated from other installations on a regular basis. Normally, a Spectacle Blind Flange is installed in the “open” position, allowing flow through the pipe.
