30 KN Rated Power 4 KW Pipe Bursting Equipment with 720-895 mm Length for Trenchless Pipeline Replacement

Pipe In-situ Replacement System—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.
