🚀 Pipeline Expander Overview
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.
Equipment Features:
- Main System: Automatic threaded tie rod traction enables one-button push/pull operation, reducing labor intensity by 70%.
- Quick Installation: Lightweight quick-install locking kit at the manhole end allows single-person installation in 1 minute.
- Hydraulic Power: Features automatic directional switching and pressure self-locking with dual overload protection.
- Remote Operation: Equipped with wireless remote control for safe and efficient operation away from the shaft.
