Stainless Steel Spectacle Blind Flange
Application:
"Spectacle Blind Flange" is a type of flange used in piping systems, particularly in industries such as oil and gas, chemical processing, and petrochemicals. This specialized flange consists of two metal discs connected by a central section or handle. One of the discs has an opening or hole, while the other is solid. By aligning the handle with either the opening or the solid portion, the flow of fluid through the pipeline can be controlled.

Product Details
Types of Line Blinds
Line Blinds come in three basic forms: Spectacle Blinds, Figure-8, and Paddle Blinds. These devices are used to isolate or 'turn off' portions of piping systems. Line blinds can be used together with a valve or instead of a valve. In the image on the right, we see an installed Spectacle Blind in the 'open' position.
The name "spectacle blind flange" is derived from its appearance, resembling the shape of the eyeglasses frame "spectacles" when viewed from the side, with the handle resembling the bridge of the glasses. This flange plays a crucial role in ensuring the efficient and safe operation of piping systems in various industrial settings.The spectacle blind is sometimes sold split into it’s two parts, the line blank, and the ring spacer.
Line Blanks:The solid side of the spectacle blind can be referred to as a line blank, skillet blind, paddle blank, paddle blind, or spade. It forms a positive shut-off when used alone or as half of a spectacle blind. The line is a 'wafer style' device, designed to fit inside the bolt hole circle. A flange spreader is shown on the right being used to prepare a pair of flanges to accept a line blank and two gaskets. To maintain the spacing of the flanges when the line is open, a ring spacer is used.
