HDPE Prestressed plastic corrugated pipe is an ideal product to replace the original metal corrugated pipe in bridge and building construction. Plastic bellows are divided into round pipe and flat pipes, which are connected with various plastic connectors in practical use.

1. HDPE Spiral Plastic Corrugated Pipe Equipment Introduced

The HDPE prestressed plastic corrugated pipe production equipment manufactured by our company integrates the advanced technology at home and abroad, adopts the method of direct crushing and forced feeding, recycles, and then enters the single screw extruder. and maintains the shape through vacuum and water cooling. Finally, the tractor replaces the manual conveying of products. The whole process is controlled by PLC control system, integrating the advantages of intelligence and efficiency, The difference between this machine and the module forming machine is: no sealing line on the surface, very beautiful, high hardness and corrosion resistance. Our company’s production equipment is used in the production of spiral bellows runway threaded under Shenzhen airport.

2. Advantages of Prestressed Plastic Corrugated Pipe Introduced

1)  Good physical properties

Non conductive, can prevent stray current corrosion, good sealing performance, no rust, small load, non permeability, high strength, high stiffness, good impact resistance, not afraid of stepping on pressure. It can reduce the friction loss of prestress in the process of tensioning.

2) Performance characteristics

It is flexible and hard. It is not afraid to step on it and is not easy to be chiseled

Corrosion resistance, aging resistance, not easy to be corroded by sewage and chemicals. Black pipes are resistant to ultraviolet light and increase the service life. The drainage and sewage discharge are smooth, the flow resistance in the inner cavity of the pipe is small, the water capacity is strong, and the total flow is large.

3) Purpose and function

Prestressed plastic corrugated pipes are used in post-tensioned prestressed concrete structures as perforated pipes for prestressed tendons. It has corrosion resistance and improves the anti-corrosion protection ability of prestressed reinforcement. It is an ideal product to replace the original metal bellows in bridge and building construction. It is widely used in highway overpass, viaducts, railway bridges, tunnels and other concrete projects.

◎ municipal road engineering: as the seepage and drainage pipe of railway and expressway.

◎ industrial production: generally used as sewage pipe in industrial production industry.

◎ engineering buildings: rainwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc.

◎ sewage collection pipe of waste treatment plant.

◎ large and medium-sized seaport and port engineering projects: drainage and sewage pipes of large and medium-sized airports, seaport and port engineering projects.

◎ sports competition venues: water seepage drainage pipes used as golf courses, football fields and other sports competition venues.

◎ water conservancy project construction: as water source pipe and irrigation pipe.

◎ mining plant: as natural ventilation of coal mine

3. Conclusion: 

General name of prestressed plastic corrugated pipe: bridge prestressed bellows, prestressed plastic spiral pipe, concrete bellows, prestressed cast-in-situ plastic bellows, bridge plastic bellows and steel strand bellows. HDPE prestressed plastic corrugated pipe is mainly used in post-tensioned prestressed concrete structures and hole forming of components. It has the advantages of good sealing, no water seepage and slurry leakage, high ring stiffness, small friction coefficient, aging resistance, electric corrosion resistance, good flexibility, not easy to be chiseled by tamping rod and new connection mode, which makes the construction connection more convenient, and solves all the disadvantages of traditional metal bellows. In the near future, this kind of durable and environment-friendly pipe will be continuously enriched and used.
