The ASME B16.48 is used in maintenance systems where opening and closing of pipe systems is required. In the carbon steel spectacle blind flange belong to the pipeline isolation device class of ASME B16.48. According to the need of a raised face, the spectacle blinds could be used. On the other hand where gasket with tight sealing is involved, the spectacle blind figure 8 could be used. These could be rotated to change positions from closed to open and vice versa.


What Is Difference Between Spectacle Blind And Spacer?

  • Spectacle Blind : In any piping spectacle blind flange is used to close the system of fluid flow with the possibility of opening it without having to fully dismantle the system. The bolts have to be loosened for a precision flange spectacle blind to be rotated into the open or closed position. Rajtilak Metal provides a detailed asme b16.48 flange weight chart for the clients to select from. We also offer a variety of spectacle blind flange dimensions to pick up from. Our spectacle blind flange price is very much affordable to the clients.

  • Spacer Flanges : Spacer is basically a spectacle flange without the permanent connection to the second disk. Paddle Spacers are made from forged steel and comply with standards.


Why Spectacle Blind Flange– Known As A Figure-8 Blind?

ASME B16.48 Stainless Steel Spectacle Blind Flange– also known as a figure-8 blind – is generally a piece of metal that is cut to fit between two gaskets and usually sandwiched between two pipe flange. A ANSI B16.48 Blind Spectacle Flange is often made from two metal discs that are attached to each other by a small section of steel. These ANSI B16.48 Spectacle Blind Flange Raised Face meet the requirements of various industries like heavy engineering, and railways engineering, automobile, pipeline.
