HDPE/PP Krah pipe production line

Carat tube, also known as HDPE winding structure wall tube, is made of high-density polyethylene resin as the main raw material, adopts hot-wound molding process, and is made of polyethylene (PP) single-wall corrugated tube as support structure with high external pressure resistance. The ability to special structural wall tubing. The product has a smooth inner surface and an externally shaped reinforced structure. The standard length of the pipe is 6 meters, the domestic diameter is 300mm-4000mm, the weight is light, and the overall flexibility is good. It is the main pipe preferred for buried sewage.

The carat tube has good flexibility, and the local pipe section has strong rigidity and overall resistance to external pressure. It has corrosion resistance, aging resistance, long service life, and can be recycled 100% without any toxicity. The inner wall of the pipe is rough. The rate is low and the water volume is large. Therefore, in many areas such as municipal water supply and drainage, large-scale water conservancy projects, petroleum industry, coal industry, chemical engineering, environmental protection engineering, power engineering, etc., carat tubes will be used as transportation pipes in the future. And the production process of the carat tube is simple (raw material mixed feeding → extrusion winding forming → socket forming → mechanical correction), which is convenient for mass production and meets market demand.
