The Kammprofile-Octagonal RTJ is sized to the standard octagonal API 6A or ASME B16.20 dimensions but with the addition of the Kammprofile design applied to the sealing areas and faced with oxidation inhibited flexible graphite. This design is ideal for applications where cracking or embitterment has been experienced in ring joint groove. It is available in a large variety of metal material and it can be fabricated as custom engineered designs.
Kamm-PEG represents a Pressure Energized Gasket with Kammprofiled sealing surfaces, where a RX type ring is typically used for high pressure reactors. Frequently, custom ring are used in the top and bottom of hydro processing reactors. To greatly enhance sealing ability, top and bottom OD angled sealing gasket surfaces are serrated per Kammprofiled specifications and faced with oxidation inhibited flexible graphite. It has the benefits of under compression graphite flows into minor imperfections creating higher seal tightness.
