Six-sided Pipeline Expander for Uniform Circumferential Force and Structural Rehabilitation of Localized Pipe Collapses
The six-sided expander is designed for rapid trenchless repair of localized pipe collapses. This innovative technology positions jacking equipment precisely at the collapse site via traction, using hydraulically driven, synchronously expanding jack plates to restore pipe integrity.
- Six-sided Synchronization: Hydraulic expansion plates operate simultaneously at equal frequency and pressure for uniform force distribution
- Automatic Centering: Self-aligning mechanism ensures perfect concentricity with existing pipe
- Superior to Traditional Methods: Eliminates stress concentration and secondary damage risks of two-point expansion systems
- Adjustable Diameter: Modular design covers DN200 to DN700 specifications for various pipe types
- Cost-Effective Solution: Single-point repair eliminates excavation and relining requirements
Trenchless repair of localized collapses, deformations, and misalignments in:
- Corrugated pipes
- PE pipes
- Corrugated steel pipes
- Steel-reinforced pipes
- Spiral-wound solid-wall pipes
- Thin-walled steel pipes
Ideal for urban underground water supply/drainage, gas, power, and communication networks.
