Basic Information:
The HDPE double-wall corrugated pipe production line integrates advanced extrusion and molding technologies to manufacture durable pipes with a corrugated outer layer and smooth inner wall. Key components include HDPE material feeders, single-screw extruder, precision corrugation molds, vacuum cooling systems, haul-off units, and automatic cutting devices. Computerized controls ensure uniform wall thickness and stable waveform formation. The produced pipes offer exceptional advantages: high impact resistance, chemical stability, and flexibility due to HDPE properties, while the dual-wall design enhances load-bearing capacity and hydraulic efficiency. Lightweight yet robust, these eco-friendly pipes are ideal for drainage, telecom, and industrial applications, ensuring long-term performance and cost-effectiveness.
Application areas of double-wall corrugated pipes:
-
Stormwater and Sewage Drainage Systems - Widely used in municipal and industrial wastewater management for efficient fluid transport.
-
Telecommunication Cable Protection - Safeguards underground fiber optic and electrical cables from moisture and mechanical damage.
-
Agricultural Irrigation Networks - Facilitates water distribution in farmland with corrosion-resistant and flexible piping solutions.
-
Road and Railway Infrastructure - Serves as subsurface drainage pipes to prevent waterlogging and enhance structural stability.
-
Landfill Leachate Collection - Ensures safe containment and transportation of hazardous liquids in waste disposal sites.
