Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flange.
Standards: ANSI, MSS, API, AWWA, DIN, JIS, BS and GB.
Pressure classes range: from 150lbs to 2,500lbs.
Sizes range: From 1/2" to 84".
Materials: Carbon steel, stainless steel and alloy steel.
Printing: Carbon steel and alloy steel with yellow print, black print, oil or zinc.
R type ring joint gaskets are available in oval or octagonal cross section and manufactured in accordance to API 6A and ASME B16.20 to suit API 6B and ASME/ANSI B16.5 flanges. The oval ring fits the round and flat bottom ring groove flange, while the octagonal shape fits only the modern flat bottom groove flange.
The RX type RTJ gasket is manufactured in accordance to API 6A and ASME B16.20 to suit API 6B and ASME/ANSI B16.5 flanges. The RX is a pressure energized version of the R octagonal gasket and fits the R type flat bottomed groove. The RX has an increased height and utilises the internal system pressure to energise and improve the seal as internal pressure increases. Some RX sizes have a pressure relief hole to equalise pressure both sides of the sealing faces.
The BX type RTJ gaskets are manufactured in accordance with API 6A and are suitable for use in high pressure API 6BX flanges. The gaskets form a metal to metal seal on assembly and the efficiency improves as internal pressure increases. All BX sizes have a pressure relief hole to equalise pressure across sealing faces.
