Chongqing Gree Successfully Developed a Large Diameter Pipeline

The large-caliber plastic spiral wound pipe invented by Chongqing Gree Industrial Technology Co., Ltd. has passed expert appraisal in Chongqing recently. The product has obtained a number of national patents. Its maximum diameter has exceeded 5 meters. Theoretically, it can process pipelines of any diameter and any length. It can also be double-layered and multi-layered to enhance the strength and rigidity of the pipeline. According to reports, the large-diameter plastic pipe is a world-class problem. The diameter of the domestic pipe has not been able to break through 2 meters. Grentech's technology has filled the gap in the production of the world's large-caliber pipe.
Plastic spiral winding pipe can be used for renewable resources such as waste polypropylene, polyethylene plastic, etc., which is not only low cost, light weight and environmental protection. The unique spiral spiral winding inlay processing method developed by the Gree Company realizes the plate production of the pipeline and can be wound according to the needs of the site. This new technology and new structure make the pipeline production more convenient and simple.
Due to the advantages of convenient construction, high strength, good rigidity, corrosion resistance, and aging resistance, plastic spiral wound pipes are gradually replacing traditional concrete pipes and become a new type of pipe for municipal water diversion, sewage drainage, and agricultural irrigation. After nearly half a year of trial, the company's large-diameter pipeline has been laid for dozens of kilometers, achieving an output value of more than 20 million yuan, which has broad market prospects.
