The working of ring joint gaskets (RTJ Gasket) can be explained by the axial compressive load causing them to deform and flow to irregularities in the flange grooves that it seals. As load bearing area of ring joint gaskets (RTJ Gasket) are small high surface stresses are produced between the sealing face and the groove, making it poor in recovery characteristics and unfit for reuse.
We manufacture from R 11 through R 105 to suit the following flange specifications:
The Octagonal cross section Ring Joint is the development oval cross section and offers a better sealing performance. Only oval cross section gaskets can be used when the flange grooves are with the round bottom. Both Octagonal and oval cross sectioned gaskets can be used when the grooves of the flange are having a flat bottom.
Surface finish of the Style R Ring Type Joint sealing faces (radiused ends of an Oval and the 23° angled faces of an Octagonal shape) shall not be greater than 1.6 μm Ra /63 μin RMS. Flexitallic Style R Ring Type Joints can bemanufactured in accordance with all relevant standardsto suit the following flange designations:
API 6A
ASME16.20
R Oval & Octagonal gasket ring Can be used for ASME B16.5 flange class 150 to 2500 and API 6B to Class 5000 »Soft iron and carbon steel gaskets are zinc plated to prevent corrosion » All rings are marked with the ring number, material and the date of manufacture and API designation.
