In recent years, in the construction of urban drainage, industrial pipe networks and comprehensive pipe corridors, the application frequency of PE carat pipes (HDPE wound reinforced pipes) has increased significantly. Several practical engineering cases show that this type of pipe is gradually replacing traditional concrete pipes and ordinary plastic pipes, becoming the preferred choice in municipal and infrastructure fields.

In a drainage system renovation project in a Binhai New Area, PE carat pipes exhibited excellent corrosion resistance. The soil in this area has high salt content, and traditional metal pipes have multiple corrosion perforations after less than five years of use. PE carat pipes, due to their high-density polyethylene material and structural winding reinforcement process, effectively resist chemical medium erosion, and remain intact after ten years of use.

Another case occurred in a highway drainage project in a soft soil foundation area. Due to the obvious geological settlement, rigid pipelines are prone to dislocation and fracture. The construction party adopts PE carat pipes with ring stiffness class SN12. Its flexible interface design allows the pipeline to maintain sealing under settlement conditions, greatly reducing the frequency of maintenance and reducing the maintenance cost throughout the life cycle.

In addition, the construction efficiency of PE carat pipes is also recognized. For example, a comprehensive pipe gallery project in a development zone needs to complete pipeline laying before the rainy season. Traditional pipelines require concrete encapsulation and maintenance, and the cycle is long. PE carat pipes are connected by socket electric fusion, which does not require pouring of foundations. The laying progress can reach more than 300 meters in a single day, greatly shortening the construction period.

From the technical characteristics, the PE carat pipe combines the high ring stiffness of winding and the flexibility of thermoplastics, which not only overcomes the shortcomings of traditional plastic pipes that are easy to deform, but also avoids the problems of excessive weight and transportation difficulties of concrete pipes. Its interface sealing performance has passed the national standard test and can meet the requirements of 7-8 degree earthquake fortification area.

In summary, PE carat pipe has become an important direction for modern engineering pipeline selection due to its comprehensive advantages of corrosion resistance, settlement resistance and fast construction. With the continuous optimization of manufacturing process and the continuous expansion of application scenarios, this type of pipe will continue to play a key role in sustainable development infrastructure building.
