The machine winds the profiles and steel strips simultaneously

Scope of Application

Applicable pipe diameters: DN800–DN3000.

Applicable pipe types: Various drainage pipelines, large-diameter pipes, and box culverts; suitable for the rehabilitation of reinforced concrete pipes and PVC pipes.

Technical Features

1. 1. Wide Applicability: Operations can be performed while water is flowing; requirements for internal flow conditions are minimal, and the process is easy to operate. It is compatible with various pipe types—including large-diameter pipes, box culverts, reinforced concrete pipes, and PVC pipes—enabling structural rehabilitation across the board.

2. 2. Simple Installation: Construction equipment is highly integrated, ensuring efficient installation; a single section can be rehabilitated within 4 to 6 hours.

3. 3. Excellent Hydraulic Performance: The rehabilitated pipe features a smooth inner wall, significantly improving flow capacity and substantially enhancing the pipe's structural strength.

4. 4. High Toughness: The liner exhibits high ductility and toughness, making it suitable for rehabilitating pipes with varying diameters, bends, misalignments, or irregular shapes, as well as pipes subject to significant dynamic loads.

Social and Ecological Benefits

1. Reduced Rehabilitation Costs: The spiral winding rehabilitation technique offers relatively low material costs; combined with a short construction period, this results in lower labor and equipment expenses.

2. Extended Service Life: The rehabilitated pipe demonstrates excellent corrosion and aging resistance, significantly extending its service life and reducing future maintenance and replacement costs.

3. Enhanced Flow Capacity: The smooth inner wall of the rehabilitated pipe improves flow capacity, thereby optimizing the efficiency of the drainage system..

4Ensuring public safety: Eliminates safety hazards for pedestrians and vehicles caused by potholes from road excavation and construction zones.

5. Green construction: Materials undergo only physical changes during the process, ensuring an eco-friendly, pollution-free operation.
