Stainless steel Figure-8 flanges
Stainless steel Figure-8 flanges, also known as Spectacle Flanges, are a special type of blind piping component used to isolate a section of pipe for maintenance, inspection, or testing without removing the flange from the pipeline. They consist of two flanges connected by a web: one side is a full bore (like a regular flange) and the other side is blind (solid), forming a “figure-8” shape.
