A whole is put at the halfway mark of the bridge. These are also called spectacles, figure 8’s, and figure 8 blanks, because of their resemblance to reading glasses (spectacles) and figure 8’s. These are referred to as ‘Line Blanks’ in the ASME/ANSI standards. </p> <p align="justify">The second and third types are quite similar: both have longer bridges, referred to as ‘paddles’, which resemble longer handles. One type has only an OD, and so is a blind plate – similar in appearance to a large pizza oven peel. These are referred to as paddle blinds.</p> <p align="justify"> The other type is exactly the same but comes with an ID as well, enabling flow-through when installed in a piping system. These pieces have holes in the paddle which enables field personnel to determine by sight which piece is installed in a system. These are referred to as paddle spacers, and are often supplied in sets together with the paddle blinds.</p> <p align="justify"> All 3 types of these flanges are used in piping systems or pressure vessels where the flow needs to be interrupted from time to time. They are installed between two pipe flanges (as specified above), and by way of a screw inserted into the hole in the bridge or paddle, they are able to rotate or ‘swing’ into and out of position to interrupt or allow the flow, as the user sees fit. Our spec blind flanges are available with raised, flat, or RTJ faces. </p> <p align="justify">This is a flange plate which as its name implies is shaped like a pair of spectacles only in this case one spectacle is open and the other is blanked off. This plate is installed in the pipeline between a pair of flanges. In normal operation the plate is installed with the open side in the pipeline so it does not restrict the flow. However, once the pressure has been taken off the flange plates can be loosened and the spectacle plate changed to put the blind side in the flow. This will completely seal off the flow making the line safe to work on.</p>, Manufacturer of high quality Spectacle Blind Flange in Dandong, Manufacturer of best quality Spectacle Blind Flange in Dandong, Price of Spectacle Blind Flange in Dandong

Separating one part of a line from another requires a spectacle blind, able to switch from closed to open and back again. Bleed rings provide a means to release pressure from the pipe through a controlled opening. Spectacle flanges are known for their tensile strength, dimensional accuracy and durability. These flanges are made by using best quality material. We offers an extensive range of spectacle flanges in various dimensions and specification.The first and most widely used type are spec blinds – short for spectacle: these are flanges with two equal outside diameter (OD) parts welded together by way of a ‘bridge’.
