What is a Spectacle Flange?

A Spectacle Flange, also known as a Spectacle Blind Flange or Figure-8 Blind, is a pipeline device consisting of two discs joined together — one solid (blind) and one with an opening (spacer). It is inserted between two flanges to either allow or completely block flow in a pipeline.

• Solid Side: Blocks the pipeline flow for isolation and maintenance.

• Open Side: Allows flow while maintaining spacing.

Spectacle Flanges are widely used in critical industries such as oil & gas, petrochemical, power plants, chemical processing, marine, water treatment, and pharmaceuticals due to their reliability, ease of operation, and safety.
