Abstract
A non-fragmenting, low burst pressure rupture device assembly is provided for mounting between opposed flange members which define a relief orifice for a pressurized line or vessel. The assembly includes a relatively thin, flexible, fluid impervious sealing element adapted to be carried by the flange members in fluid blocking relationship to the orifice, along with a support member adapted to be mounted in supporting relationship to the element downstream of the pressure line or vessel. The support member has a series of relieved areas therein defining a closed loop pattern presenting a section which gives way or opens under a pre-determined pressure thereon applied through the sealing element from the pressurized area. The element has an integral bulge defining part overlying the perimeter of the section which allows the section of the support member to sense the pressure in the line or vessel through the sealing element independent of the burst pressure characteristics of the sealing element. A plate secured to the sealing element on the face thereof opposed to the support member moves with and assures full rupture of the sealing element concomitantly with opening of the section of the support member.
