Abstract of Disclosure A tubular joint sealing system for use in high pressure and high temperature conditions is provided. The sealing system consists of a shape memory material backup member combined with a compliant seal. The shape memory member is deformed into an intermediate shape that is sufficiently reduced in size so as to avoid abrasive contact with the sealing surfaces of the tubular members during the mechanical makeup of the joint. Thereafter, the shape memory member may be activated to assume its memory shape configuration, which is selected to be sufficient size to form a pressure and fluid-tight seal.
