Product Overview
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.

Equipment Features
Main System

Automatic threaded tie rod traction enables one-button push/pull operation, reducing labor intensity by 70%. Lightweight quick-install locking kit at the manhole end allows single-person installation in 1 minute.

Hydraulic Power Unit

Features automatic directional switching and pressure self-locking with dual overload and leakage protection. Equipped with manual/automatic integrated solenoid valves and wireless remote control.

Operation Safety

Standard wireless remote control enables operators to work safely and efficiently away from the shaft opening, ensuring high reliability in infrastructure development.
