PVC-UH Drainage Pipe

PVC-UH Drainage Pipe is a high-strength drainage solution developed for deep-buried and heavy-load applications. Compared with conventional PVC-U drainage pipes, it provides higher ring stiffness, stronger impact resistance and improved resistance to external pressure and deformation. The pipe can withstand temporary deformation and recover its shape, making it suitable for buried drainage systems under major roads, heavy-traffic areas and other demanding conditions.

With socket-and-spigot joints using elastomeric sealing rings, the system provides reliable sealing while accommodating a certain degree of ground settlement. Full-pipe inspection and controlled manufacturing help maintain consistent ring stiffness and overall product performance.
