Spectacle Blind Flanges also referred to as figure-8 blind flanges, These are generally pieces of metal. Spectacle blind flange move fit between two pipe flanges and typically sandwiched between two gaskets. A spectacle blind is usually made up of two metal discs that are attached to every other by Little section of steel. The form is similar to a pair of glasses or “spectacles” — hence the name spectacle blind. One end of the blind will have a gap to permit flow through the pipe during operation and the other end is solid to block flow during maintenance. They’re generally installed as a permanent device to the separate process piping systems.

When to use a Spectacle Blind Flange

Spectacle Blind Flange applied in systems, which is regularly need to be separated from other installations. Normally, a Spectacle blind flange is mounted within the “open” position in order that flow through the pipe is possible. If the Spectacle Blind within the “close” position is rotated, the pipe is blanked off and no flow is possible.

Maintenance on a pipe system are often a reason to temporarily replace a ring Spacer flange for a Spade flange. By loosening of all bolts, and half the bolts temporarily remove, the Spade or Spacer are often placed. After replacing the gaskets, the bolts are often re-assembled and tightened. The pipeline should be pressure relieved and valved off before loosening the flange bolts. To stop unnecessary weight to a flange connections, designer will usually choose the separate two parts (spacer flange and spade flange) rather than the Spectacle Blind Flange.
