About Spectacle Blind Flange
A Spectacle Blind Flange, also known simply as a spectacle flange or figure-8 blind, is a specialized type of flange used in piping systems for the purpose of isolating sections of pipelines or equipment temporarily or permanently. Spectacle blind flanges are primarily used for maintenance or inspection purposes in piping systems where it's necessary to isolate a section of the pipeline. They consist of two metal discs connected by a central section, resembling the shape of a pair of glasses or a figure-8, hence the name "spectacle."
-
Design: The design of a spectacle blind flange consists of two metal discs that are attached to each other by a central spacer or spectacle piece. The spectacle piece is typically made from a similar material as the flange itself and is a solid bar with holes for bolting.
-
Flange Faces: Spectacle blind flanges have the same flange faces as other types of flanges, such as raised face (RF), flat face (FF), or ring type joint (RTJ), depending on the sealing requirements of the piping system.
Components:
- Blind Discs: These are the solid metal discs that can be rotated to open or close the flow. They are typically held together with bolts and nuts.
- Spectacle Piece: This is the central part that connects the two blind discs. It has holes for the bolts and allows the discs to rotate into the desired position.
