Spectacle Blind Flange of ASME Carbon Steel


Definition Of Spectacle Blind Flange:

A spectacle blind flange – also known as a figure-8 blind – is generally a piece of metal that is cut to fit between two pipe flanges and usually sandwiched between two gaskets.

It is a safety device used to isolate a section of line or piece of equipment when the line or equipment needs to be inspected or removed from service. It is different than a valve in that the blind is a permanent or long term isolation device.
