Introduction to Flanges
Flanges are crucial components in piping systems. They are flat, circular discs with holes that are used to connect pipes, valves, pumps, and other equipment to form a piping network. Flanges provide easy access for cleaning, inspection, and modification of the piping system. They also allow for the disconnection of parts of the system for maintenance or repair. Flanges come in various types, such as weld - neck flanges, slip - on flanges, blind flanges, and socket - weld flanges, and are made from different materials including carbon steel, stainless steel, alloy steel, and non - ferrous metals like brass and aluminum.
