Product Brief
Prestressed Corrugated Pipe Production Line is automated extrusion molding equipment specially used to manufacture plastic corrugated pipes for prestressed concrete structures. Adopting continuous extrusion technology, it takes HDPE and PP as raw materials. The production line can produce two types of prestressed corrugated pipes: circular pipes and flat pipes. The finished pipes serve as protective sleeves for prestressed steel strands, and this machine is the key plastic corrugated pipe extrusion equipment for prestressed engineering material manufacturers.
Product Specifications
- Raw Materials: HDPE (High-density Polyethylene), PP (Polypropylene)
- Finished Products: prestressed corrugated pipe, circular type & flat type
- Production Flow: Raw material mixing → Extrusion plasticization → Corrugation forming → Cooling shaping → Traction cutting
- Product Characteristics: Acid & alkali resistance, anti-aging, tight sealing, low friction coefficient
- Target Application: Protection duct for prestressed steel strands
Main Advantages
- Supports both HDPE and PP raw materials, flexible production of circular and flat prestressed corrugated pipes.
- Automated continuous extrusion molding, stable production and high output efficiency.
- The finished pipes feature acid-alkali resistance, anti-aging performance and excellent sealing effect.
- Low friction coefficient inside pipes, effectively protects prestressed steel strands during construction.
- Integrated compact structure, easy operation and convenient daily maintenance.
Application & Usage
The production line manufactures plastic corrugated ducts for prestressed construction. Finished prestressed corrugated pipes are widely used in bridges, highways, railways, high-rise buildings and other prestressed projects, acting as protective sleeves for prestressed tendons (steel strands) inside concrete structures.

Production Process
Raw material mixing → Extrusion and plasticization → Corrugation forming → Cooling shaping → Traction cutting → Finished prestressed corrugated pipe collection
Working Raw Material
HDPE (High-density Polyethylene) particles and PP (Polypropylene) particles. The raw materials provide outstanding anti-aging, acid and alkali resistance, making the finished pipes durable inside concrete projects.
