Double-Wall Corrugated Sewer Pipe Extrusion Line
This advanced production line is specially designed for the
efficient manufacturing of double-wall corrugated drainage pipes,
widely used in municipal sewage systems, stormwater drainage,
highway engineering, agricultural irrigation, and underground cable
protection.
Equipped with a high-performance extrusion system, the line ensures
stable output, uniform wall thickness, and excellent pipe ring
stiffness. The precision corrugator system forms a smooth inner
wall and a reinforced corrugated outer wall, providing superior
strength, impact resistance, and long service life.
The production line features intelligent PLC control, automatic
temperature regulation, synchronized forming technology, and
high-speed cooling systems to guarantee continuous and reliable
operation. It supports a wide range of pipe diameters and materials
such as HDPE and PP, meeting various international standards.
With energy-saving design, easy maintenance, and high production
efficiency, this line is an ideal solution for large-scale drainage
pipe manufacturing projects.
Fourth-Generation Double-Wall Corrugated Pipe Technology
Circumferential Continuous Sealed Pressure Water-Cooling Molding
Technology
- Fully continuous, uninterrupted water cooling
- Fixed water-cooling pipeline connection—no plugging/unplugging
required when changing molds
- Cooling section length: 6.3 meters
- Higher efficiency with lower energy consumption
- Launch year: 2013
Our Advantages
Faster Production Speed
The mold undergoes continuous circumferential pressure water
cooling throughout its full operation path, resulting in superior
cooling performance. Output can reach more than three times that of air-cooling and traditional water-cooling systems.
Lower Energy Consumption
- The extrusion system uses a buffered forced-feeding section,
significantly reducing the power consumption of the main drive
motor by 30%
- The large L/D ratio screw (36:1) ensures excellent plasticizing
performance and superior material adaptability
- Optimized die flow channel design enables low-temperature,
low-pressure pipe extrusion
Easier Operation
No need to raise or lower the forming machine platform. Mold
replacement is quick and convenient.
More Stable and Durable Operation
- Smoother movement of molds and water-cooling circuit
- Fixed water-cooling pipe connection eliminates leakage caused by
frequent plugging/unplugging, preventing equipment wear and
extending service life
- Shorter die flow path and lower pressure reduce wear, extending the
lifespan of both the screw and die
Features of the PE/PP Double-Wall Corrugated Pipe Production Line
The DWCP series double-wall corrugated pipe production line is developed by Qingdao Huashida Machinery Co., Ltd. based on
market demand and international technological trends, integrating
and enhancing the most advanced technologies from abroad. This
fourth-generation high-speed water-cooling line is suitable for the
high-speed extrusion of PE and PP materials.
The line adopts a dual-extruder co-extrusion forming process and is equipped with B&R professional control systems for
double-wall corrugated pipe production. It features a high degree
of automation and stable operation.
For even greater energy savings, customers may opt for original ABB inverter motors and frequency converters.
