A self-acting gap seal for a gap existing between individual modules of a composite, annular pressure vessel comprising a flat, thin-walled seal element on the inside of the pressure vessel to bridge the gap plus the circumferential region adjacent the gap. Internal pressure urges the seal element against the inner wall of the vessel to close and seal the gap to prevent exit of the pressure medium in the vessel.

A self-acting seal assembly for a circumferential gap between adjacent pipe ends of a pressure vessel adapted for carrying a pressure medium at a pressure greater than ambient pressure, said seal assembly comprising a seal element closing said circumferential gap under the internal pressure in the vessel by the pressure medium, the adjacent pipe ends of the vessel at said gap having inner surfaces for guiding axial and radial movement of said seal element, said seal element including a flexible, relatively thin-walled element capable of flexing across its width, said adjacent pipe ends being constituted by the ends of pipe elements forming said vessel, said pipe elements having walls which collectively define the wall of the vessel, said adjacent pipe ends of the vessel being provided with recesses having bounding surfaces forming said surface which guide the radial and axial movement of the seal element, said seal element being accommodated in said recesses with clearance radially and axially and acting under the internal pressure to engage said bounding surfaces and close said circumferential gap, said seal element including a strip wound as an annular element with overlapping ends.
