A flange is defined as a plate type device, normally 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 all the different materials to match
the material of the pipe and fittings to which they are being
attached. While some flanges are made of Cast Iron, the vast
majority of flanges are forged carbon steel.
Forged steel flanges are made in seven primary ratings: Class 150,
