ASME/ANSI B16.48 Spectacle Blind Flange – Spectacle Blind Flange ASME/ANSI B16.48 Spectacle Blind Flange Supplier A spectacle blind flange, often referred to simply as a “spectacle blind,” is a specialized piping component used to seal off a pipeline for maintenance or system isolation. It consists of two metal discs: one solid and one with a hole.
The solid disc is used to block the flow of fluid, while the perforated disc can be used when flow is required. The name “spectacle” comes from the shape of the two discs, resembling a pair of spectacles or glasses when viewed from the side. Typically made from materials like
carbon steel, stainless steel, or alloy steels, spectacle blind flanges are used in industries such as oil and gas, chemical processing, and water treatment, providing a reliable method of controlling flow and ensuring safety during system shutdowns or maintenance. They are designed to be bolted between two flanges and are
available in various pressure ratings and sizes to suit different operational requirements.
