More Information
Summary:A bulged, forward-acting rupture disc (10) and a pressure relief device (38) incorporating a rupture disc (10), having a line of opening (28) formed in the transition region (26) of the disc between the bulged section (12) and flange section (14) are provided. The line of opening (28) is a stress-concentrating feature that, in conjunction with a stress-intensifying edge (68) located on an associated outlet ring (42), facilitates opening of the disc (10) when exposed to a predetermined pressure acting upon the concave face (20) of the bulged section (12).
