Mesh Stent Expansion for Non-Overlapping Collapsed Pipe Repair

The replacement pipe is divided into multiple expandable segments or cells that can be inflated independently. This segmentation allows the pipe to expand uniformly without overlapping, as each segment expands in place rather than requiring the entire pipe to uncurl and overlap.

The replacement pipe transitions from a static coil shape to a dynamic expandable structure. By using inflatable segments that can be expanded on-demand, the system adapts to the pipe geometry without requiring pre-formed overlapping sections, thereby eliminating the harmful overlap effect.

The support structure transitions from a static prefabricated plate to a dynamic inflatable segment system. The segments can be inflated to various diameters as needed, allowing the repair process to adapt to different pipe sizes without requiring pre-manufactured plates for each diameter, thereby significantly reducing wait-time and improving productivity.

The diameter parameter of the support structure is changed from fixed (prefabricated) to variable (inflatable). By controlling the inflation pressure and volume of the segments, the support structure can achieve the precise diameter needed for any given pipe, eliminating the need for multiple prefabricated sizes and reducing manufacturing lead-time.

The pipe interior is segmented into multiple expandable cells that distribute the expansion force uniformly. This prevents the formation of overlapping sections that would create turbulence and energy loss, as each cell expands smoothly in place to restore the full internal volume without creating constrictions.

The expansion is made homogeneous by using multiple inflatable segments that expand uniformly around the pipe circumference. This creates a smooth, continuous internal surface without overlapping sections, maintaining optimal hydrodynamic conditions and minimizing energy loss from turbulence and friction.
