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 way to create a leak - tight joint and allow for easy disassembly and reassembly of the piping system for maintenance, inspection, or modification. They 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. The materials used to manufacture flanges include carbon steel, stainless steel, alloy steel, and non - ferrous metals like aluminum and brass, depending on the nature of the fluid being transported, temperature, and pressure conditions.
