Metallic sealing rings (ring-joint gaskets) for API ring-type-joint flanges used in oil and gas extraction piping. The ring seats in machined grooves in both flange faces and seals by controlled plastic deformation, giving reliable performance at high pressures and temperatures. Select the ring profile and material to match the flange groove and the process medium; rings are generally single-use after compression.
