Abstract
A joint for forming a sealed junction between two large diameter cylinders or rocket motor casings. A tongue-and-groove arrangement employs a pressure-energized metal seal which expands radially when the cylinders are internally pressurized. The radial expansion enhances the sealing effect of the metal seal between the tongue and the groove. The metal seal will withstand extreme pressures and temperatures which can adversely affect the sealing capability of elastomer O-rings.
