"RTJ" stands for "Raised Face, Tongue, and Groove" flange. It is a type of flange used in piping systems to connect pipes, valves, and other equipment. The raised face provides a seal when the flange is bolted to another flange, and the tongue and groove design helps to align the flanges during assembly. RTJ flanges are commonly used in high-pressure and high-temperature applications.
