Applications and features of Class 1500 and Class 2500 spectacle blind flanges

Class 1500 and Class 2500 spectacle blind flanges are commonly used in high-pressure piping systems. These flanges are designed to fit between two pipes or flanges, and they can be rotated to either block or allow flow through the system. The Class 1500 and Class 2500 designations refer to the pressure ratings of the flanges, with Class 1500 flanges rated for pressures up to 1500 psi and Class 2500 flanges rated for pressures up to 2500 psi.

Spectacle blind flanges are typically used in applications where it is necessary to isolate a section of piping or equipment for maintenance or repair. By rotating the spectacle blind flange, the flow of fluid can be blocked off without the need to shut down the entire system. This allows for maintenance or repair work to be carried out on a specific section of the system while the rest of the system continues to operate.

The design of the spectacle blind flange consists of two metal discs with a raised central section that fits between two flanges. The discs are held together with a central bolt that allows the flange to be rotated. The raised central section of the flange can be shaped to match the profile of the adjoining flanges, ensuring a secure and leak-proof connection.
