A metallic spring member 30 cooperates with grooves 32, 34 disposed in pressure containing members 10, 12. The spring member 30 has an E-shaped cross section and is compressed both horizontally and vertically when the members 10, 12 are fully engaged. The seal is self-energizing under normal operating conditions and able to accommodate small, but significant relative motion between the pressure containing members 10, 12 during conditions of abnormally high and unevenly distributed temperature. |
