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, Class 300, Class 400, Class 600, Class 900, Class 1500 & Class 2500
