Abstract: A reversing rupture disc assembly for protecting a vessel or other apparatus from excessive pressure has a carrier ring mountable in the apparatus and a reversing rupture disc tightly positioned in the ring. The disc has a curvature obtained by imparting a force thereto so as to strain the material from which the disc is made. The disc is disposed in the ring, so that the convex surface of the disc is directed toward the pressure. The disc has a weak buckling zone located in the mid-region of the disc, whereby the disc buckles inwardly and ruptures in response to the excessive pressure, the disc deviating from a spherical form at the mid-region, so that the radius of curvature of the disc decreases going from the mid-region to the edge of the disc and, so that the sector angle phi of the disc is greater than 3.82 square root S/R, where S is the disc thickness and R is the average radius of curvature of the disc. The material of which the disc is made has a positive stress-strain curve after undergoing the strain required to obtain the curvature, the curve having a slope d sigma /d Epsilon greater than about 100 kgf/mm2.
