US Patent 11186462 Inflatable pipe drum systems and methods

Techniques for implementing and/or operating a pipe drum system that includes a drum body. The drum body is to be disposed within an interior channel of a pipe coil that is formed from a flexible pipe including tubing that defines a pipe bore and a fluid conduit within a tubing annulus. The drum body includes a drum core implemented with substantially fixed dimensions and a fluid bladder layer implemented circumferentially around the drum core. The pipe drum system maintains the fluid bladder layer in a first state to enable the drum body to be inserted into the interior channel of the pipe coil after the pipe coil is formed and increases inflation of the fluid bladder layer from the first state to a second state to enable an outer surface of the drum body to push against an inner surface of the pipe coil to facilitate supporting the pipe coil.
