In municipal drainage and sewage projects, the long-term reliability of the pipe directly determines the operating cost of the pipe network. The traditional cement pipe is gradually being replaced by more advanced pipes due to its own weight, easy leakage of the interface, and insufficient corrosion resistance. The wound B-carat pipe uses high-density polyethylene as the main raw material and adopts the hot winding molding process. The pipe wall has T-shaped reinforcing ribs. The structure design is ingenious, and the balance between ring stiffness and lightweight is achieved.

Compared with cement pipes, the advantages of wound B-type carat pipes are reflected in many dimensions. The material itself is resistant to acid and alkali corrosion, can effectively resist chemical erosion in domestic sewage and industrial wastewater, and will not gradually loosen due to internal calcium dissolution like cement pipes. The pipeline adopts socket-type electric fusion connection or rubber ring flexible interface, which has reliable sealing performance and can avoid the risk of staggered leakage caused by foundation settlement of rigid interface. During construction, the weight per unit length of carat pipes is only about one-tenth of that of cement pipes of the same diameter, no large lifting equipment is required, the amount of trench excavation is small, and the laying speed is fast, which significantly shortens the construction period and reduces the comprehensive construction cost.

From the perspective of the whole life cycle, the inner wall of the wound B-type carat tube is smooth, the Manning roughness coefficient is low, the water transmission resistance is small, the long-term operation is not easy to scale, and the maintenance frequency is much lower than that of the cement tube. Its design life can reach more than 50 years, and the material can be recycled, which is in line with the trend of green construction. For the buried drainage scene that requires high ring stiffness, by adjusting the wall thickness of the structural layer and the parameters of the rib tube, the carat tube can easily meet the requirements of different covering depths and avoid overload deformation.

Overall, the winding B-type carat pipe has become a practical alternative to traditional cement pipes due to its reliable durability, convenient construction, and full-life economy, providing a more optimized technical path for the construction of modern drainage pipe networks.
