Introduction to Flange
A flange is a flat, circular disk with holes around its perimeter, used to connect pipes, valves, pumps, and other equipment to form a piping system. It provides a way to make a joint that can be easily assembled and disassembled for maintenance, inspection, or modification. Flanges come in various types, such as weld - neck flanges, slip - on flanges, blind flanges, and socket - weld flanges, each designed for specific applications and pressure requirements. They are crucial components in industries like oil and gas, chemical, power generation, and water treatment.
