About Ring Type Joint Flange
A Ring Type Joint (RTJ) flange is a type of flange designed to create a tight seal between two pipes or between a pipe and a valve under high-pressure and high-temperature conditions. RTJ flanges are typically used in critical applications where leakage can be detrimental, such as in oil and gas exploration and production, petrochemical processing, and power generation.
-
Raised Face (RF) RTJ Flanges:
- Raised Face RTJ flanges have a raised portion around the pipe bore, which serves as a sealing surface for the RTJ gasket. The raised face helps to center the gasket and provides a smooth surface for sealing. These flanges are commonly used in lower pressure and temperature applications.
-
Ring Type Joint (RTJ) Flanges Without Raised Face:
- These RTJ flanges do not have a raised face around the pipe bore. Instead, the sealing surface is directly on the flange face itself. These flanges are typically used in high-pressure and high-temperature applications where a raised face is not necessary or may interfere with the sealing performance of the RTJ gasket.
Both types of RTJ flanges use a metal ring gasket, such as octagonal or oval-shaped, to create a tight seal between mating flanges. The choice between raised face and non-raised face RTJ flanges depends on the specific requirements of the application, including pressure, temperature, and the type of fluid being transported.
