Figure 8 is a kind of pipe fittings, mainly for the convenience of maintenance. You can know the specific shape by painting the upper part of the "8" black. It is half blind and half iron ring. It is often used for pipeline flanges that need to change the process. The materials are mainly carbon steel, stainless steel, and alloys, which can be selected according to the pipeline pressure level and pipeline medium.Spectacles blind flange
Spectacle blind flanges, also known as figure-eight blind flanges, are flanges used in pipelines to temporarily or permanently close off a section of pipeline. It consists of two metal discs with a metal "bridge" (glasses) in between, forming a figure 8. One of the discs has a raised surface for bolting to the adjacent flange, while the other is flat to provide a blind closure. The spectacle shutter fits between two flanges and it can be rotated to a flat disc position for a closed shutter or a raised face for an open position. This allows for easy inspection or maintenance of the pipe without removing the entire pipe section.
