The main functions of flanges are as follows:

Realizing Connection: Flanges, as a disc-shaped component, are mainly used to connect two pipes, fittings, or equipment. They are fixed by bolts or other fasteners to form a reliable connection and can withstand various pressures, temperatures, and media tests.
Sealing performance: A gasket is usually placed between two flanges. When the bolt is tightened, the gasket is compressed to provide a sealing effect, effectively preventing gas or liquid leakage and ensuring the normal operation of the pipeline system.
Easy to disassemble and repair: The flange connection is easy to disassemble. When a component needs to be repaired or replaced, simply loosen the bolt to remove the flange, without damaging the entire pipeline system, saving time and cost, and improving work efficiency.
