DN600 SN16 carat tube, high ring stiffness winding tube

DN600 SN16 carat pipe is a high ring stiffness winding structural wall pipe. It is made of high density polyethylene as the main raw material and formed by continuous winding process. Its nominal diameter is 600 mm, and the ring stiffness grade reaches SN16, that is, it can withstand a radial pressure of 16 kN per square meter, which gives the pipe excellent anti-deformation ability under deep burial or heavy-duty traffic. The pipe wall adopts a hollow reinforcing rib structure, which effectively reduces its own weight while ensuring ring stiffness, making it easy to hoist and install.

The pipe adopts socket type electrofusion connection or rubber ring flexible interface, the sealing performance is reliable, and it can adapt to a certain degree of soil sedimentation. The inner wall is smooth, the Manning roughness coefficient is low, the head loss when transporting fluid is small, and the long-term operation energy consumption is lower. The raw material is resistant to acid and alkali corrosion, and has good chemical stability to domestic sewage, industrial wastewater and rainwater. The designed service life can reach more than 50 years.

In practical projects, DN600 SN16 carat pipes are often used in urban trunk road drainage pipe networks, sewage treatment plant inlet pipelines, rain and sewage diversion systems in industrial parks, and highway culverts. Its high ring stiffness characteristics are especially suitable for areas with large covering soil depth or high groundwater level. It can effectively resist external pressure loads and avoid pipe buckling failure. During construction, foundation treatment and backfill compaction are required according to specifications, and coarse sand or gravel is symmetrically backfilled around the pipe to ensure that the pipe and soil work together to give full play to the structural strength. Correct selection and installation can greatly improve the overall reliability and maintenance cycle of the pipe network system.
