A Spectacle Blind is a safety device used to isolate a section of pipeline or
equipment when inspection or maintenance is required. Unlike valves, spectacle
blinds provide a permanent or long-term isolation solution.
They are machined from a single piece of metal designed to match the pipe size
and installed between two pipe flanges with additional gaskets. Bolt length
requirements depend on the piping class and blind thickness, which is determined
based on line pressure and pipe size.
