Urban pipe network is the "blood" of urban operation, and key functions such as water supply, drainage, and gas transportation depend on its stable operation. However, with the increase of service life, changes in geological pressure, and the influence of external loads, traditional pipes are prone to corrosion and leakage, structural damage, etc., which not only causes waste of resources, but also may cause safety hazards such as road collapse and water pollution. In this context, HDPE carat pipe has become an ideal choice to improve the safety of urban pipe network due to its unique advantages. HDPE carat pipe is made of high-density polyethylene as raw material, which has strong chemical corrosion resistance and can resist the erosion of harmful substances in sewage, rainwater, and soil, and avoid pipeline rupture due to corrosion. Its special winding structure design endows the product with high ring stiffness, which can withstand external shocks such as ground vehicle loads and soil pressure, and greatly reduce the risk of pipeline deformation. Compared with traditional concrete pipes and steel pipes, HDPE carat pipes are lighter in weight, more flexible, more convenient in construction, have little impact on the surrounding environment, and reduce pipeline damage caused by improper construction. At the same time, its surface smooth water flow resistance is small, not easy to block, and has excellent anti-ultraviolet and anti-aging properties. It can maintain long-term stability in complex climates and prolong the service life of pipe networks. It can be said that HDPE carat pipes have built a solid barrier for the safety of urban pipe networks through material innovation, structural optimization and performance improvement, helping cities build a safe bottom line in development and bringing more reliable protection to residents' lives.
