The HDPE Double Wall Corrugated Pipe Production Line is designed for the efficient production of high-strength corrugated drainage pipes. The finished pipes feature a smooth inner wall and corrugated outer wall, providing excellent ring stiffness, impact resistance, corrosion resistance, and long service life.
Widely used in municipal drainage systems, sewage treatment projects, highway drainage, agricultural irrigation, cable protection, and infrastructure construction, this production line offers stable performance, high automation, and low operating costs.
Qingdao Huashida Machinery has over 20 years of experience in plastic pipe extrusion equipment manufacturing. We provide complete turnkey solutions, including equipment design, installation, commissioning, operator training, and after-sales technical support, helping customers achieve efficient and stable production.
Features of large caliber PE spiral drainage pipe:
1).High Ring Stiffness
2).High Brunt Intensity and low weight
3).Good creep deformation resistance.
4).Outer pressure resistance.
5).Erosion resistance ( such as acid ,alkali and salt etc.)
6).Long life of approximate 50 years. No pollution and so on.

Composite Reinforced Structure: First extrudes a high-strength square single-wall pipe as the structural core, then synchronously spirally winds molten PE adhesive material around it, forming a composite pipe with both high ring stiffness and flexibility.
Energy-Efficient Plastication: The extruders employ a unique variable-pitch, barrier-type screw design and a high-efficiency mixing system. This achieves low-temperature, low-energy consumption plastication tailored for high molecular weight materials, significantly increasing extrusion capacity while ensuring plastication quality.
Intelligent Synchronous Control: The entire line is centrally managed by an advanced PLC computer control system. Through touch-screen interfaces, it enables synchronized automatic control over the square pipe extrusion, adhesive extrusion, spiral winding, and cutting processes, ensuring process coordination and operational reliability.![]()
