Carbon Steel Figure-8 blind flanges, commonly referred to as Carbon Steel Spectacle Blind Flanges, are typically made Carbon Steel. Carbon Steel Spectacle Blind Flanges are often sandwiched between two gaskets and trimmed to fit between two pipe flanges. A common construction method for a Carbon Steel Spectacle Blind Flange involves joining two metal discs together with a thin piece of carbon steel. The moniker "spectacle blind" comes from the shape, which resembles a pair of glasses. The blind will have a solid end for blocking flow during maintenance and an opening on one end to enable flow through the pipe when it is in use. They are typically set up permanently to divide the pipe systems used in processes.

The moniker "spectacle blind" comes from the shape, which resembles a pair of glasses. The Carbon Steel Spectacle Blind Flange will have a solid end for blocking flow during maintenance and an opening on one end to enable flow through the pipe when it is in use. They are typically set up permanently to divide the pipe systems used in processes. The entire purpose of a Carbon Steel Spectacle Blind Flange is to ensure that there is no chance of any flow or leakage through a valve during maintenance and that an item of equipment is properly and securely blanked off. However, the flow cannot simply be bypassed around the blank because doing so would jeopardise the safety function of the Carbon Steel Spectacle Blind Flange. Instead, it can be diverted to other pieces of equipment. Before releasing the flange, bolts and swinging the blind, the flow must be valved off and the pressure released.
