Abstract
A trailer for cylindrical fluid containers, particularly compressed gas tubes, arranged in modules individually removable from the trailer. Each module has a front and a rear bulkhead between which tubes are supported. The tubes have reduced cylindrical ends which protrude through and are supported in openings in the bulkheads. At least one end of the tubes is threaded and clamped by a nut or a collar flange to a bulkhead. Each bulkhead has a stiffening, right-angle flange along each vertical edge which aligns with and is clamped to each adjacent module. At their bottom, the bulkheads abut and are attached to an upwardly extending side of an L-shaped structural member, the other side being mounted to the trailer frame. The tubes are arranged in line horizontally and vertically with space between them.
