PVC-U Hollow Spiral Pipe is precision manufactured from high-quality polyvinyl chloride (PVC) resin through advanced extrusion technology, combining the structural advantages of a hollow double layer and internal spiral reinforcement. The double-layer hollow structure enhances the pipe’s overall rigidity and impact resistance, while the internal spiral ribs guide water to flow along the pipe wall, forming a stable wall-attached flow state. This unique design not only optimizes drainage efficiency but also significantly reduces noise caused by water impact and turbulence. All matching silencing fittings are produced via precision injection molding, with dimensional parameters perfectly matched to the hollow spiral pipe to ensure tight and leak-proof connections. The product adopts a bonded connection method, which provides excellent sealing performance and ensures the integrity of the entire drainage system. Rigorously tested in CNAS laboratories, the pipe exhibits outstanding resistance to acids, alkalis, and corrosion, and can withstand harsh working conditions such as underground pressure and chemical erosion in industrial drainage. The smooth inner surface of the pipe prevents scaling and sediment accumulation, minimizing fluid resistance and reducing the risk of blockages. Whether used in deep underground municipal pipelines or indoor drainage systems, PVC-U Hollow Spiral Pipe maintains stable performance, long service life, and consistent reliability.

Product Specification
Superior Mechanical Strength: The internal spiral reinforcement structure and double-layer hollow design work together to provide excellent pressure resistance, impact strength, and tensile strength, enabling the pipe to withstand underground soil loads, construction impacts, and long-term fluid pressure without deformation or damage.
Efficient Drainage Capacity: The spiral rib structure guides water to form wall-attached flow, increasing flow velocity and improving drainage capacity compared to traditional pipes. It effectively handles large flow rates such as rainwater and concentrated drainage, reducing the risk of water logging.
Outstanding Noise Reduction: The double-layer spiral structure and wall-attached flow design minimize water impact on the pipe wall and turbulent flow, significantly reducing drainage noise. When paired with silencing fittings, it achieves a quieter effect, making it suitable for noise-sensitive environments.
Cost-Saving Integration: The design integrates drainage and ventilation functions into a single pipe, eliminating the need for additional ventilation pipes and fittings. This reduces material costs, simplifies installation processes, and lowers labor and construction expenses.
Durable Corrosion Resistance: High-quality PVC-U resin material offers excellent resistance to acids, alkalis, and various corrosive substances, ensuring stable performance in industrial wastewater, chemical drainage, and municipal sewage environments. Its service life is far longer than that of steel pipes.
Lightweight and Easy Installation: With a density of 1/5 to 1/6 that of steel pipes, the pipe is lightweight and easy to transport and handle. The bonded connection method and precise fitting matching simplify on-site installation, shortening the construction period and reducing labor intensity.
