Product Description
HDPE double-wall corrugated pipe is a type of plastic pipe made from high-density polyethylene. It is a new type of pipe that combines performance and environmental protection advantages. With a unique hollow structure design, it has high ring stiffness and strong compressive capacity, enabling it to adapt to the complex buried environment of municipal engineering. The smooth inner wall results in low water flow resistance, and the flow capacity is significantly improved compared with traditional pipes. Moreover, it is resistant to acid and alkali corrosion and has good anti-leakage performance. Its service life can reach over 50 years, greatly reducing the post - maintenance cost.

Application Scenarios
1.It is used for the collection and discharge of municipal rainwater, sewage transportation, and drainage in underground utility tunnels.
2.It can meet the wastewater discharge requirements of different industries such as chemical engineering, food processing, and electronics manufacturing.
3.It is suitable for water conveyance in agricultural drip irrigation and sprinkler irrigation systems as well as farmland drainage, enabling water - saving irrigation, flexible installation, and timely drainage of waterlogged fields.
QA&QC
1.Raw material control: HDPE double-wall corrugated pipes are made from high-density polyethylene resin, with a density generally ranging from 0.941 to 0.965 g/cm³.
2.Production process: HDPE double-wall corrugated pipes are manufactured using the extrusion process. During the forming process, parameters such as the mold temperature and vacuum degree are precisely controlled to ensure technical indicators such as the ring stiffness of the pipes.
3.Finished product inspection: The appearance of the pipes should be free of defects. The inner wall should be smooth without bubbles, cracks, depressions and other defects. In addition, tests on the ring stiffness and flexibility of the pipes are also carried out.
4.Certifications: ISO9001 Quality Management System Certification and CE Certification.
