Product Description
Pipe In-situ Replacement System
Pipeline Expander
The expansion method for in-place replacement utilizes specialized expander to generate controlled radial expansion forces within existing pipes. This uniformly enlarges or splits the old pipe diameter while simultaneously pulling new pipe into the expanded cavity. This single-pass process completes pipe rehabilitation by "expanding and replacing" without excavation or additional working pits.
