Abstract
Closure modules are coupled to and enclose ends of a multi-cell pressure vessel, especially a multi-cell pressure vessel having arcuate outer wall segments connected by internal web segments that define a plurality of cells in the pressure vessel. The closure modules each have an arcuate surface portion and at least one interfacing surface portion integrally connected at a marginal extent thereof with a marginal extent of the arcuate surface portion. The arcuate surface and interfacing surface portions define a closure module chamber and have peripheral edges. The arcuate surface portion of one of the closure modules abuts contiguously against an interfacing surface portion of an adjacent one of the closure modules. The closure modules are particularly useful for use with multi-cell tanks and vessel bodies, especially tanks and vessels suitable for storing liquid propane.
