Product Description

B16.5 A105 Carbon Steel Blank Flange 
Product introduction
Figure-8 Blank, also known as figure 8 flange or spectacle blind flange which is combination of the two that can be rotated to function as Single Bind or a Ring Spacer. This kind of flange is generally a piece of metal than is 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 flange. 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 system.
Spectacle Blind Flange  is usually used on the oil line with two different functions:
If the spade is put in between the flanges, it stops the fluid's passage;
If the spacer is put in between the flanges, the passage of the fluid is allowed.
