Abstract
A reverse acting rupture disc and methods of forming the same are provided. Generally, the rupture disc comprises a bulged portion and a circumscribing flange area surrounding the bulged portion. The bulged portion includes a mechanically formed line-of-opening recess comprising a singular channel. In certain embodiments, the mechanical process by which the recess is formed utilizes a high-speed mill which removes a portion of metal from the bulged portion of the disc without disrupting the substantially uniform metallic grain structure of the metal adjacent the channel.
