Abstract
A rupture disc (10) is provided comprising a line of opening (16) formed in at least one face thereof. The line of opening (16) is formed by laser machining of the disc's face and includes at least one disc opening control feature (20). The disc opening control feature (20) may be an opening-initiation feature configured to assist with initial rupture of the disc (10). Alternatively, the opening control feature (20) may be an anti-fragmentation feature configured to dissipate the energy acting upon the disc (10) so as to prevent separation of the petal formed upon opening of the disc.
