Ring Type Joint Flanges (RTJ Flanges) are a type of flange used in high-pressure and high-temperature piping systems. They are commonly used in the oil and gas industry, as well as in chemical and petrochemical plants.

RTJ flanges are designed to provide a tight seal between two pipes or between a pipe and a valve or other equipment. The flanges are fitted with a metal ring that sits in a groove on the flange face, which provides the sealing surface. The ring is typically made of a soft material, such as carbon steel, stainless steel, or Inconel, that is designed to deform under pressure and fill the irregularities on the flange face, creating a tight seal.

There are several types of RTJ flanges, including oval, octagonal, and lens-shaped. The shape of the ring is determined by the shape of the groove in the flange face. Each type of RTJ flange has a specific sealing surface area and pressure rating, which must be carefully matched to the requirements of the piping system.

RTJ flanges are typically more expensive than other types of flanges, due to the additional machining required to create the grooves in the flange faces and the precision required to ensure a tight seal. However, their high pressure and temperature ratings make them essential components in many critical piping systems.
