PVC-UH Drainage Pipe
High-Strength, High-Ring-Stiffness PVC-UH Piping for Deep-Buried & Heavy-Load Drainage
Nominal Diameter:DN110–DN1600
Connection:Solvent Socket Joint / Elastomeric Sealing Ring Joint
Applications:Non-Pressure Drainage & Sewerage
Customization:Diameter · Pressure Rating · Connection · Color
Product Description:
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.
