A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
Types of flanges
| Weld neck flanges | Slip-on flanges |
| Threaded flanges | Lapped flanges |
| Socket-welded flanges | Blind flanges |
