A flange is defined as a plate-type device, typically round, that is attached to the end of a pipe, fitting, valve, or other object to facilitate the assembly and disassembly of a piping system.
Flanges are manufactured in various materials to match the pipe and fittings to which they are attached. While some flanges are made of cast iron, the vast majority are forged carbon steel.
