Corrugated HDPE Double-Wall Water Supply Pipe
Double-walled corrugated pipe is a multi-purpose municipal pipeline mainly made of plastic particles as raw material by extrusion and shaping. The inner wall is smooth and flat, and the outer wall is corrugated (trapezoidal, circular wave, etc.). Its unique pipe wall structure makes the double-walled corrugated pipe have the characteristics of high ring stiffness, light weight, high pressure resistance, good toughness, corrosion resistance, good wear resistance, convenient construction, low installation cost, long service life, etc., it is widely used in municipal transformation projects, construction, industrial and agricultural drainage, agricultural water-saving irrigation, sewage treatment projects and other fields.It is the best alternative to traditional cement pipes, cast iron pipes and other material pipes.
According to the different cooling and setting methods and efficiency of horizontal machines, the industry divides the double-wall corrugated pipe production line into three generations of products, while Huashida's double-wall corrugated pipe is the fourth-generation product developed on the basis of the third-generation technology.
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 features a closed water-cooled structure. The mold base drives the left and right modules to move along a closed curve. Utilizing a gear-driven mechanism, the mold base offers several advantages, including automatic compensation for mechanical wear, smooth operation, low noise, extended service life, and high synchronization. Additionally, the unique design of the circulating water circuit ensures high reliability, effective cooling, and minimal water impact within the pipeline. These features enhance the reliability of continuous pipe production and ensure the high-quality surface formation of the pipes.
