PE double wall corrugated pipe

PE double wall corrugated pipe is a new type of lightweight pipe made of polyethylene as raw material, processed through extrusion and special molding processes, with smooth inner walls and closed corrugated outer walls.

Formation principle of PE double wall corrugated pipe
① For the PE double wall corrugated pipe formed by hydraulic pressure, the principle is to use liquid pressure in the pipe blank to expand and form it in a restricted ring. It can be compressed along the ring direction all the way to reach the desired length. This method is commonly used for small diameters.
② Roll forming is mainly used for processing large pipes, relying on the forming wheel in the pipe for rolling and forming. Plastic corrugated pipes can be made with a single wave, of course, some devices can make several waves at once.
③ Mechanical bulging is a type of mold that uses internal expansion, and after forming, it is customized with internal and external pressure.
Product Features
① Long service life: Under normal use, the service life of PE double wall corrugated pipes can reach 50-100 years, much higher than that of cement pipes or metal drainage pipes. Especially in relatively harsh use, their service life may differ by 10 to several years.
② Safe and non-toxic: using vinyl resin that can reach the hygiene level of drinking water transportation, suitable for large-diameter long-distance gravity self-cleaning water supply pipelines, without causing secondary pollution to the transportation medium.
③ Good fluidity: The Manning number of PE double wall corrugated pipe is the same as that of other structural wall plastic pipes, which is 0.01; The Manning number of cement pipes is 0.013, so under the same caliber and usage conditions, the conveying capacity is 30% higher than that of cement pipes.
④ Green and environmentally friendly: PE double wall corrugated pipes can achieve green and environmentally friendly production, use, and recycling processes. There is no wastewater, exhaust gas, or waste generated during their manufacturing process, and they do not pollute the environment. When burned, only carbon dioxide and water vapor are produced, and no other harmful gases are emitted.
⑤ The overall cost of the project is low: For large-diameter pipelines, considering manufacturing costs, transportation and installation savings, the comprehensive cost of the entire corrugated pipe project is slightly lower than that of cement pipes due to the smooth and flat inner wall, which can transport larger medium flow rates (about 15%) with the same diameter as cement pipes. However, the service life is greatly extended.
⑦ No leakage: The structure is advanced, and the joints between the strips are uniform and firm. The pipeline section is also well sealed.
⑧ Easy installation: Due to the double flat structure of the inner and outer walls, socket connections are used between pipes and between pipes and inspection wells, making installation convenient and fast.
⑨ Pipeline adaptation to non excavation construction: Due to the double wall structure of the pipe wall, the actual tensile strength of the pipe wall fusion joint is twice the inspection value. Thus, the corrugated tube has both rigidity and flexibility. After rigorous destructive experiments, it has been proven that it can withstand harsh environments, resist ground subsidence, and adapt to non excavation construction.
⑩ The pipeline wall thickness is uniform and consistent, and the performance is consistent: Due to the uniform and consistent thickness of the pipe wall (non corrugated), there are no weak links, so the pipe wall performance is uniform and consistent.
