Abstract:
A set of closure modules for constructing therewith an end closure structure for a multi-cell pressure vessel which comprises a body portion comprising a plurality of arcuate outer wall segments connected by internal web segments so that the arcuate outer wall and internal web segments collectively define cells having opposite ends, said set of closure modules comprising:a first closure module comprising an arcuate surface portion and an interfacing surface portion, the interfacing surface portion having a marginal extent integrally connected with a marginal extent of said arcuate surface portion, said arcuate surface portion and said interfacing surface portion defining, collectively or in combination with at least one additional interfacing surface portion, a closure module chamber with a closure module opening, said closure module opening being defined at a periphery thereof by either free edges of said arcuate surface portion and said interfacing surface portion or free edges of said arcuate surface portion, said interfacing surface portion, and said at least one additional interfacing surface portion; and a second closure module adjacent the first closure module, the second closure module comprising an arcuate surface portion and an interfacing surface portion, the interfacing surface portion having a marginal extent integrally connected with a marginal extent of said arcuate surface portion, said arcuate surface portion and said interfacing surface portion defining, collectively or in combination with at least one additional interfacing surface portion, a closure module chamber with a closure module opening, said closure module opening being defined at a periphery thereof by either free edges of said arcuate surface portion and said interfacing surface portion or free edges of said arcuate surface portion, said interfacing surface portion, and said at least one additional interfacing surface portion, wherein said interfacing surface portion of said first closure module abuts contiguously against said interfacing surface portion of said second closure module.
