A flange is a projecting rim or edge, typically circular in shape, that is used to strengthen or attach one object to another. It is often found on pipes, wheels, and other mechanical components, and can be either flat or raised. Flanges are commonly used in construction, engineering, and manufacturing industries to provide a secure connection between two separate parts. They can also serve as a sealing mechanism, preventing leaks or fluid loss. The term ‘flange’ can also refer to the act of attaching or fastening two objects together using this type of rim or edge. Overall, flanges play a crucial role in ensuring the stability and functionality of various structures and equipment.
