HDPE Double wall corrugated pipe

what is a HDPE Double Wall Corrugated pipe ?

Is a pipe using two different layers using materials from high density (high density) Polyetheline (PE). The inside is smooth and even. On the undulating outside, the nominal diameter (ID) is divided into two; outer diameter and inner diameter.

Ring Stiffness or strength in a corrugated HDPE pipe is a measure of the ability of a pipe to withstand circular deformation (pressure).

In 1980, the German manufacturing company for the first time in the world made a two-wall corrugated pipe used in an underground sewer system that was able to last for more than 50 years

Performance characteristics of double wall corrugated pipe

  • The product is novel in material, reasonable in structure and high in strength.
  • The product structure adopts the force principle of I-beam, the moment of inertia is increased, and the ring stiffness is improved, so that the double-wall exhibits high mechanical properties. The results obtained by experiments show that when the average deformation rate of the diameter in the vertical direction reaches 3.14%, the pipe top load can reach 60 tons.
  • Compared with the solid wall pipe, the DWC pipe has characteristics of light weight, material saving and energy consumption saving.
  • Under the same load conditions, it can save about 40% of raw materials compared with solid materials of the same material and the same specifications.
  • The double-wall corrugated pipe has a smooth inner wall and a large flow rate, and the same flow rate (compared to the cast iron pipe and the concrete pipe) has a small diameter.
  • The inner wall roughness coefficient is only 0.009, and the concrete roughness coefficient is 0.013. In the case of the same pipe diameter, the water flow rate of the double-wall corrugated pipe is 30% larger than that of the concrete pipe. We commissioned the relevant testing institutions to do the hydraulic test. Three conclusions are drawn from the experiment:
