Factors to consider when choosing the right Figure 8 blind flange

There are several factors to consider when choosing the right cobra blind flange for your piping system. These include

Material

The material of the flange should be compatible with the material of the piping and the fluid or gas being transported.

Size

The size of the flange should match the size of the piping to ensure a secure and leak-free connection.

Pressure Rating

Flanges should be rated to withstand the maximum pressure of the piping system.

Temperature Ratings

Flanges shall be rated to withstand the maximum temperature of the piping system.

Corrosion Resistance

Flanges should be corrosion-resistant to ensure that they will not corrode over time, leading to leaks and other safety hazards.
