... graphite packer seal rings that are not affected by thermal changes. Thus, the approach to HPHT sealing systems for 15 ksi (103 MPa) flowlines is to develop a graphite and steel ring system that will not leak even with nitrogen gas at 1.5 times the 15 ksi MAOP. The authors developed a graphite packer seal...
