RTJ stands for Ring Type Joint, and a RTJ flange is a type of flange that is designed to handle high pressure and high temperature applications. It uses a metal ring gasket to create a seal between the flange faces. RTJ flanges are commonly used in the oil and gas industry, as well as in chemical and petrochemical plants. They are available in various sizes, pressure ratings, and materials to suit different piping systems.
