What is Ring Joint Flange?
A ring joint flange is a machined metallic ring grade that has deep grooves cut on its face. These grooves rest on the metal rating and can be compressed with bolts, allowing them to be easily tightened. The flanges are generally seen across high pressure and temperature services. They are produced in standard sizes up to 24 inches and can be availed in standard specifications.

Difference between RF and RTJ Flange

• An RF flange is characterized by a raised face and is usually affixed to the bolting circle. An RTJ flange uses bolts to affix them to the subsequent grooves.
• The rtj flange is well equipped to fend off movement and vibration compared to an RF flange.
• RTF flanges are more viable in applications that are difficult to access compared to the RF flanges.
• RF flanges can be fixed with different types of gaskets. There is a limited option while fitting gaskets of an RTJ flange.

RTJ Flange assembly
An RTJ flange uses a steel ring on which the gasket rests. The sealing is achieved via the deformation process of the soft metallic gasket. The strong metal-to-metal sealing is achieved by tightening them with bolts.

How does a RTJ flange work?
An RTJ flange creates a metal-to-metal seal compressing pressurized media in the system. Designed with different grades of steel these flanges help in the movement of high pressure and temperature fluids. These flanges are easy to assemble and disassemble within the system.

When to use ring-type joint flanges
The RTJ flanges are typically utilized in high-pressure conditions of class 600 or above. These flanges compress the gasket ensuring metal-to-metal sealing. They come in handy as a replacement for raised flanges, especially in areas where space is limited.

Ring Joint Flange vs. Raised Face

• A ring type joint flange has grooves cut in its face, which allows them to compress the bolts in place. Raised face flange has a raised surface that allows them to strongly create a sealing with the bolting area.
• Ring joint flanges have a limited choice in selecting gaskets. Raised face flanges can be affixed with different types of gaskets.
• Replacing a worn gasket is easier in the raised face flange than in a ring joint flange.
