Introduction to Flanges
Flanges are crucial components in piping systems. They are flat, circular discs with holes around the perimeter that are used to connect pipes, valves, pumps, and other equipment to form a complete piping network. Flanges provide a convenient way to assemble and disassemble the piping system for maintenance, inspection, or modification. They also ensure a tight and leak - proof connection, which is essential for the safe and efficient operation of various industrial processes. Flanges come in different types, such as weld neck flanges, slip - on flanges, blind flanges, and socket weld flanges, each designed for specific applications and pressure requirements.
