The present invention relates to collapsible hoses and inflatable structures such as pneumatic actuators for water control gates that are manufactured on and incorporate into their structure a flexible internal mandrel with rounded edges. One face of the mandrel and all of its rounded edges separate from the inflatable membrane during pressurization, while the remaining face of the flexible mandrel remains bonded to the remaining face of the inflatable envelope. Sharp internal edges (in the deflated condition) and their associated stress concentrations (in the inflated condition) are thus eliminated.
