UPVC Gravity Sewer Pipe Features
In addition to good physical and chemical properties of UPVC pipes and fittings, the following outstanding features are also available.
1. High Strength & Durability
PVC material provides excellent impact resistance and mechanical strength, capable of withstanding external pressure when buried underground.
Resistant to chemical corrosion, suitable for domestic sewage, industrial wastewater, and rainwater discharge.
2.Lightweight & Easy Installation
Compared to traditional concrete or cast iron pipes, PVC drainage pipes are lighter, facilitating transportation and installation.
Features push-fit joints or rubber ring seals for quick and secure assembly, reducing construction time.
3.Superior Hydraulic Performance
Smooth inner surface with low friction coefficient minimizes blockages and enhances drainage efficiency.
Ideal for gravity drainage systems, ensuring long-term stable performance.
4.Eco-Friendly & Sustainable
PVC material is recyclable, meeting modern environmental standards.
UV-resistant and long-lasting, with a service life exceeding 50 years, reducing maintenance costs.
