Double-Wall HDPE Corrugated Conduit for Water Supply

In addition to the characteristics of ordinary plastic pipes, such as good corrosion resistance, high insulation, smooth inner wall, and low flow resistance, HDPE double-wall corrugated pipe also has excellent ring stiffness, good strength and toughness, light weight, strong impact resistance, and not easy to break, due to the special hollow ring structure.

Product application range:
1. Municipal engineering, underground buried rainwater and sewage discharge in residential areas;
2. Agricultural irrigation and drainage;
3. Drainage and transportation of sewage treatment plants and garbage disposal sites;
4. Chemical ventilation pipes and fluid transportation in chemical and mining industries
5. Power and communication cable protection casings, etc.

Technical characteristics of the fourth generation of Huashida
Continuous sealed pressure around the circumference of the forming module
Water-cooled setting technology
Uninterrupted continuous water cooling, the cooling pipeline is fixed, and there is no need to unplug and plug the replacement module. The length of the cooling section: 6.3 meters
High production efficiency and low energy consumption
Product launch time: 2013

The DWCP series high-speed corrugated pipe forming machine adopts a closed water-cooled structure, and the mold base drives the left and right modules to move within the closed curve. The mold base adopts a gear dynamic structure, which has the advantages of automatic compensation for mechanical wear, smooth operation, low noise, long service life, and high synchronization. The unique design of the circulating water circuit has high reliability, good cooling effect, and low water impact in the pipeline, which improves the reliability of continuous production of pipes and ensures the surface forming quality of pipes.
