UNI Flanges typically have a raised face or flat face, and they can be made from various materials such as carbon steel, stainless steel, and alloy steel. The most common types of UNI Flanges include slip-on, weld neck, blind, threaded, lap joint, and socket weld flanges.

The dimensions of UNI Flanges are specified in the UNI standard, which covers both metric and imperial sizes. The standard also specifies the material, design, and pressure ratings for UNI Flanges.

When selecting UNI Flanges, it is important to consider factors such as the pressure and temperature of the application, the material of the flange and the pipe, and the type of connection required. It is also essential to ensure that the flange is compatible with the other components in the system to ensure proper installation and operation.
