Basic Introduction to HDPE Double-Wall Corrugated Pipe Production Line
The HDPE (High-Density Polyethylene) Double-wall corrugated pipe production line is an integrated system designed for manufacturing durable, lightweight pipes with a corrugated outer wall and smooth inner wall. Key components include an extruder for melting and feeding HDPE material, a dual-layer die head to form the Double-wall structure, a vacuum calibration unit for shaping the corrugations, a cooling system to solidify the pipe, a haul-off machine for consistent pulling, and a cutting device for length customization.
The produced pipes excel in applications requiring high strength-to-weight ratios and corrosion resistance. They are widely used in municipal drainage, sewage systems, agricultural irrigation, telecom conduit networks, and industrial fluid transport. Their structural design ensures optimal load-bearing capacity and hydraulic efficiency, making them a cost-effective solution for underground infrastructure projects.
This automated production line guarantees precision, efficiency, and compliance with international quality standards.
