Introduction to Flange
A flange is a flat, circular disk with holes that is used to connect pipes, valves, pumps, and other equipment to form a piping system. It provides a means of easy assembly and disassembly, allowing for maintenance, repairs, and modifications. Flanges are crucial components in various industries such as oil and gas, chemical, power generation, and water treatment. They come in different types, including weld - neck flanges, slip - on flanges, blind flanges, and socket - weld flanges, each designed for specific applications and pressure requirements.
