Production features
High-density polyethylene (HDPE) boasts outstanding chemical stability, extraordinary aging resistance, and exceptional environmental stress cracking resistance.Double-wall corrugated pipe made from HDPE carries these remarkable characteristics. Its primary properties are as follows:
1. Double-wall corrugated pipe can endure significant external pressure.
The exterior of the Double-wall corrugated pipe features a ring corrugated structure, significantly enhancing the pipe's ring stiffness. Compared to traditional PE pipes, it achieves the required load-bearing capabilities with a thinner wall, presenting clear advantages.
2. Economical procurement costs for Double-wall corrugated pipe.
Thanks to the unique design of the Double-wall corrugated pipe, thinner pipe walls are sufficient to meet load requirements, reducing raw material consumption and lowering production costs. This results in substantially reduced procurement expenses.Double-wall corrugated pipe offers cost-effective procurement.
3. Double-wall corrugated pipe ensures ease of construction.
Given the reduced raw material usage, HDPE Double-wall corrugated pipe is lightweight, making it easier to transport and connect during construction. Opting for HDPE Double-wall corrugated pipe can significantly accelerate construction timelines and simplify subsequent maintenance, making it ideal for projects with tight schedules, limited budgets, and challenging conditions.
4. Superior flow rate and minimal friction resistance of double-wall corrugated pipe
Compared to other pipes, the flow rate of the Double-wall corrugated pipe is higher for the same diameter, allowing the use of smaller diameter pipelines to meet fixed flow requirements.
5. Double-wall corrugated pipe exhibits excellent resistance to low temperatures and impacts
With a low embrittlement temperature, HDPE Double-wall corrugated pipe can be used in winter construction with minimal temperature impact. The ring corrugated structure of the HDPE Double-wall corrugated pipe ensures outstanding impact resistance.
6. Double-wall corrugated pipe demonstrates high chemical stability.
The non-polarity of HDPE molecules contributes to its excellent chemical stability. Except for a few strong oxidants, most chemical media cannot compromise its molecular structure. Thus, soil, electricity, and acid-base factors typically do not cause damage, bacterial growth, or scaling. The smooth pipe wall does not affect flow rate or area.
7. The Double-wall corrugated pipe offers an extended service life.
Under typical conditions, devoid of direct exposure to the sun's ultraviolet rays, the longevity of our product is truly remarkable.The High-Density Polyethylene (HDPE) Double-Wall Corrugated Pipe is engineered to last an impressive 50 years or more.
8. These Double-Wall Corrugated Pipes boast unparalleled wear resistance.
Extensive German studies reveal that the wear resistance of HDPE significantly surpasses that of traditional steel pipes, achieving durability several times greater.
9. Our Double-Wall Corrugated Pipes feature an optimal level of deflection.
Theoretically, the axial length of an HDPE Double-Wall Corrugated Pipe can exhibit slight curvature, enabling it to be laid directly into slightly irregular trenches without the need for additional fittings, thereby simplifying the construction process.
