Ring Type Joint (RTJ) Flange

These flanges are usually used in situations where there is a need for metal sealing. These conditions usually occur when the pressure and temperature are very high (for example, above 600 degrees Celsius). In these flanges, a metal gasket is used, which is placed between the corresponding grooves. As the flange closes and the pressure increases, this metal gasket deforms and creates a strong metal sealing shield. In order for this to happen, the material of the gasket used must be much softer than the material of the flange itself and have high hammer ability.
