Polyethylene carat pipe, large diameter drainage and sewage pipe

Polyethylene carat pipe, that is, high-density polyethylene winding reinforced pipe, has shown significant advantages in the field of large-diameter drainage and sewage discharge with its unique structural wall design. The pipe is made of high-density polyethylene as the main raw material through winding molding process. The inner and outer walls are smooth, and the middle is corrugated hollow reinforcement ribs, which realizes the characteristics of light weight and high strength. Its ring stiffness can reach SN8 to SN16 level, which can withstand deep soil and traffic loads. It is suitable for municipal rain and sewage pipe network, industrial wastewater discharge and large-scale water conservancy projects. The carat pipe adopts socket electric fusion connection, and the interface seal is reliable, which can effectively prevent groundwater infiltration and sewage leakage, and ensure the long-term safe operation of the pipe network. The inner wall of the pipeline is smooth, the Manning coefficient is low, the water transmission resistance is small, it is not easy to scale, and the maintenance cost is low. At the same time, the polyethylene material is resistant to acid and alkali corrosion, anti-aging, and the designed service life can reach more than 50 years. In terms of construction, the pipe is light in weight, does not require large lifting equipment, and is fast to install, which can greatly shorten the construction period. With the acceleration of urbanization process, the demand for large-diameter drainage pipes is increasing day by day. Polyethylene carat pipes, with their comprehensive performance, have become an ideal choice for the construction of modern drainage systems. Reasonable selection and standardized construction can give full play to its advantages and help improve the urban water environment.
