Pipeline Replacement System with 1.5m/min Max Pull-Back Speed 0.8m/min Min Pull-Back Speed and 7.5KW Power Pipe Bursting Equipment

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.

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.

• 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 without heavy lifting.

• Features automatic directional switching and pressure self-locking with dual overload and leakage protection.
• Equipped with manual/automatic integrated solenoid valves and standard wireless remote control, enabling operators to work safely and efficiently away from the shaft opening.
