ABSTRACT:
A low pressure venting panel acts to safely vent a pressure vessel, such as a bag house, from overpressure conditions. The venting panel is particularly responsive and predictable at low pressures. The panel includes a thin rupture body with a central group of apertures and slit lines emanating from the apertures. A thin sealing membrane is bonded to one surface of the rupture body at least in the area of the slits. The characteristics of the sealing membrane enable the membrane to resist expansion in the area of the slits when pressure is applied to the rupture body, thereby resisting rupture of the membrane up to the design rupture limit of the venting panel.
