As the core facility of urban environmental protection, the stability and durability of its internal pipeline system are directly related to the efficiency and safety of sewage collection and treatment. Among many pipeline materials, HDPE carat pipe has become an ideal choice for pipeline laying in sewage treatment plants due to its unique structural design and excellent performance.

HDPE carat pipe is made of high-density polyethylene as the main raw material and is made by winding molding process. Its inner wall is smooth, which can reduce the resistance of sewage flow; the outer wall has a specific corrugated structure, which can significantly improve the ring stiffness of the pipeline. This design allows it to demonstrate multiple advantages in wastewater treatment scenarios: first, it has strong chemical corrosion resistance, which can effectively resist acid and alkali substances, oxidants, and microbial erosion commonly found in wastewater, avoid pipeline leakage due to corrosion, and ensure long-term stable operation of the system; secondly, the ring has high stiffness, which can withstand soil pressure, ground load, and internal water flow impact, and is not easily deformed or damaged even under complex geological conditions; furthermore, it is light in weight, flexible, and easy to transport and install, especially suitable for old pipe network reconstruction or complex terrain areas, which can reduce construction difficulty and labor costs; finally, the interface has excellent sealing performance, and is connected by electric fusion or heat shrinkable tape, which can effectively prevent sewage leakage and reduce pollution to surrounding soil and groundwater.

In practical applications, HDPE carat pipes are widely used in key links such as the laying of main pipelines in sewage treatment plants, the transportation of wastewater from pretreatment areas to biological treatment areas, and sludge treatment systems. For example, between the grille and the grit chamber, the sewage contains more impurities, and the corrosion resistance of HDPE carat pipes can ensure that the pipeline works stably in harsh environments; around the secondary sedimentation tank, the pipeline needs to withstand a certain ground load, and its high ring stiffness performance provides reliable support; and at the intersection or bend of the pipeline, good flexibility makes it easy to bend without a large number of piers, further optimizing the construction plan.

With the improvement of environmental protection and economic requirements for pipeline materials in municipal engineering, HDPE carat pipes are more and more widely used in sewage treatment plants due to their long life (design life can reach more than 50 years) and low maintenance costs. Choosing HDPE carat pipes that meet the standards can not only improve the operation efficiency of sewage treatment plants, but also contribute to urban environmental protection. Just as AD Pipeline always adheres to the quality concept, it provides trustworthy pipeline solutions for various projects and helps green city construction.
