Spectacle Blind Flange Manufacturers and Suppliers in India, ASME B16.48 Figure-8 Blank Dimensions, Weight Chart, Thickness Chart

Spectacle blind flanges, also known as figure-8 flanges, are a type of flange that consist of two metal discs connected by a central section, which resembles a figure 8. One of the discs is solid and the other has a hole in the center, allowing it to be rotated to either completely open or completely close the pipe.

Spectacle blind flanges are used in piping systems where there is a need for frequent maintenance or inspection of the pipeline. When the solid disc is in place, the pipeline is completely closed and the system can be shut down for maintenance or inspection. When the disc with the hole is in place, the pipeline is open and the system can be used normally.

Spectacle blind flanges are typically used in high-pressure and high-temperature applications, as they provide a strong and secure seal when closed. They are commonly used in industries such as oil and gas, chemical processing, and power generation.

Like other types of flanges, spectacle blind flanges are available in a range of materials, including carbon steel, stainless steel, and various alloys. The choice of material will depend on the specific application and the requirements for strength, corrosion resistance, and other properties.
