Industrial HDPE PP Double Wall Corrugated Pipe Extrusion Production Line

1. Product Overview

The Double Wall Corrugated Pipe Production Line is an advanced, high-speed extrusion system featuring water-cooled forming technology. Independently developed by Huashida with reference to advanced international technologies, the line is designed to manufacture single-wall and double-wall corrugated pipes using polypropylene (PP) or high-density polyethylene (HDPE) as raw materials.

The pipes produced by this line feature a lightweight structure, excellent impact resistance, strong corrosion resistance, and good tolerance to temperature variations. They are widely used in municipal drainage and water supply, underground infiltration and drainage systems, building water supply and drainage, electrical wire and cable protection, bridge cable sheathing, agricultural irrigation, and other infrastructure applications.

2. Product Features

Wide Diameter Range: Precision-engineered equipment capable of producing corrugated pipes with diameters ranging from Φ10 mm to Φ1200 mm.

High Production Capacity: Multiple machine models are available to meet different output requirements, with maximum production capacity of up to 1,300 kg/h, depending on the model and processing conditions.

Energy-Efficient Operation: An optimized machine design helps reduce energy consumption and improve overall production efficiency.

Reliable Industrial Performance: A robust mechanical structure and durable components support stable, continuous operation in demanding industrial production environments.
 

3.Production line composition:

1)Extruder:
Single-screw extruders offer a simple structure and low cost, making them suitable for applications where production requirements are not particularly high.
Twin-screw extruders offer improved plasticizing, mixing performance, and extrusion stability, enabling them to process a wider range of raw materials and achieving higher production efficiency.

2)Corrugated Forming Machine:
This allows the installed corrugated forming module to operate continuously and stably, providing the vacuuming and cooling functions required for corrugation. The design of the module's operating track significantly impacts the machine's service life and pipe quality.

3)Cooling System:
Water cooling, air cooling, or a combination of both is typically used. Water cooling offers high cooling efficiency, quickly reducing pipe temperature and improving production efficiency and pipe quality.
Air cooling is relatively simple and low-cost, making it suitable for applications where cooling speed is not a priority.

4)Cutting Equipment:
Planetary cutters or fully automatic corrugated pipe cutters are typically used, enabling precise cutting of formed double-wall corrugated pipe to a set length, achieving high cutting accuracy and smooth cuts.

5)Control System:
The advanced PLC control system enables precise control and coordinated operation of all production line components. It monitors and adjusts various process parameters, such as temperature, pressure, and speed, in real time to ensure consistent product quality.
