Expander pipeline in-situ replacement system radial expansion force replacement pipeline

Product Description

The expansion method for in-place replacement utilizes specialized expansion heads 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.

Features

Gentle Force Application: Utilizes radial expansion force rather than axial tension, subjecting manhole walls to minimal reaction forces and causing zero structural damage to chambers.

No Pipe Accumulation: Completely eliminates “pile-up” phenomena, ensuring smooth construction without pipe jamming risks.

Flexible Replacement: Supports both same-diameter replacement and one-size-up pipe diameter expansion (Up-size) to enhance flow capacity.
