High density polyethylene carat pipe, buried sewage pipe

High-density polyethylene carat pipe is a kind of structural wall pipe widely used in the field of buried drainage and sewage. It is made of high-density polyethylene as the main raw material and is made by winding molding process. The pipe wall has I-shaped or similar structural reinforcement ribs, which endows the pipe with high ring stiffness and can withstand external pressure caused by deep soil and traffic loads.

The inner wall of the pipe is smooth, the friction coefficient is low, and the head loss when conveying the medium is small, which is conducive to maintaining the smoothness of the drainage system. The material itself has good chemical corrosion resistance, which can resist the erosion of acid, alkali and salt in domestic sewage, rainwater and general industrial wastewater for a long time, without additional anti-corrosion treatment, effectively prolonging the service life of the pipe network.

In terms of connection mode, carat pipes are usually connected by socket-type electrofusion connection or sealing ring flexible connection, and the interface is tight, which can adapt to a certain degree of uneven settlement of the foundation and reduce the risk of leakage. The pipe is lighter in weight, which is convenient for lifting and transportation. The construction site can be flexibly cut and adjusted, which improves the paving efficiency.

From the perspective of engineering applicability, high-density polyethylene carat pipes are widely used in municipal stormwater and sewage pipe networks, industrial park drainage, buried drainage in building quarters, and highway culvert drainage. When designing and selecting the type, it is necessary to reasonably determine the ring stiffness grade according to the buried depth, groundwater level and soil conditions, and strictly follow the backfill compaction specifications to ensure the long-term stability of the pipeline structure. Overall, the pipe has become a mature solution in modern drainage and sewage projects with reliable mechanical properties and durability.
