ASTM A182 F316L Stainless Steel Forged Spetacle Blind Flange / Line Blanks
Spectacle Blind Flanges are also known as figure-8 blind flanges – are generally pieces of metal. Spectacle blind flange cut to fit between two pipe flanges and usually sandwiched between two gaskets. A spectacle blind is often made from two metal discs that are attached to each other by a small section of steel. The shape is similar to a pair of glasses or “spectacles” – hence the name spectacle blind.
One end of the blind will have an opening to allow flow through the pipe during operation and the other end is solid to block flow during maintenance. They are generally installed as a permanent device to separate process piping systems. is essentially a simplistic valve which fits in the line between two flanges and is bolted in place. One side of the Spectacle Blind is open (spacer) and the other side of the Spectacle Blind is blanked (blind or spade).

Application
It is used usually for maintenance when it is required to isolate a section of pipe or isolate a device. Because this is a semi-permanent isolation it is very e and ety is often the mentality behind the use of a Spectacle Blind in maintenance operations.
