Double wall Corrugated pipe

The company introduced European double-wall Corrugated pipe production equipment and technology to produce Φ110-Φ500mm PVC-U double-wall corrugated pipe. Besides, the company owns PE double-wall Corrugated pipe production line, which is advanced in domestic market, to produce DN225-DN1200 HDPE corrugated pipe. The company has a total production capacity of 20000 tons of various corrugated pipe with high quality. The company can carry out comprehensive test for the characters of pipe, Such as ring stiffness, ring suppleness, impact strength, and oven test etc. Therefore, the quality of the product is guaranteed. The double-wall corrugated pipe is mainly used in public facilities, drainage pipe network of residential area, farmland irrigation, drainage pipe network of chemical plant and sewage treatment plant, low-pressure liquid transmission as well as ventilation and drainage of chemical plant and mine, and protective pipes for optical fiber cable etc. APPLICATION SCOPE OF PVC-U AND PE DOUBLE-WALL CORRUGATED PIPE 1-Drainage pipe network of public facilities and residential area. 2-Irrigation and drainage pipe network of farmland. 3-Drainage pipe network of chemical plant and sewage treatment plant. 4-Low-pressure liquid transmission of chemical plant and mine, and mine ventilation and drainage pipe network. 5-Protecive pipes for Optical fiber cable and electric cable.
