Perforated HDPE Corrugated Pipe: Durable and Resilient; Can be Connected via PP Socket Fusion Welding
Perforated Large-Diameter HDPE Corrugated Drainage Pipe
HDPE double-wall corrugated sewage pipes are manufactured from high-density polyethylene. They are produced through a one-step molding process involving the simultaneous co-extrusion of the inner and outer walls by separate extruders. The inner wall is flat and smooth, while the outer wall features a corrugated profile. Characterized by a ring-shaped outer wall and a hollow layer situated between the inner and outer surfaces, this pipe boasts a unique structural design that delivers high strength. The complete production workflow consists of the following stages: Extrusion – Compounding – Molding – Cooling – Cutting – Finishing.
Perforated Large-Diameter HDPE Corrugated Drainage Pipe
1. Key Features:
Lightweight construction, high ring stiffness, ease of construction, transportation, and installation, low installation costs, high UV resistance, and excellent flexibility. Compared to other pipes of the same diameter, HDPE double-wall corrugated pipes offer higher flow rates due to their smooth inner walls.
2. Structural Efficiency:
The HDPE double-wall corrugated pipe utilizes a ring-structured pipe wall and an optimized corrugated profile. This design endows the pipe with greater strength-relative to its unit weight-as well as appropriate flexibility, thereby enabling a more efficient utilization of raw materials.
3. Reliable Connection and Leak Prevention:
The HDPE double-wall corrugated pipe features a reinforced design at the socket joint, complemented by a rubber sealing ring. This configuration ensures that the connection between pipe sections remains exceptionally firm and reliable. Furthermore, strict dimensional control of the socket joints facilitates easier installation and ensures highly effective leak prevention.
