Product Description

Product Description

PVC-U Solid Wall Spiral Pipe is precision-manufactured from high-quality polyvinyl chloride (PVC) resin using advanced extrusion technology. Its defining feature is the internal spiral rib structure embedded within the solid wall, which guides water to flow along the pipe’s inner surface in a stable, wall-attached spiral pattern. This design minimizes direct impact between water and the pipe wall, significantly reducing turbulence and associated noise. The solid wall construction ensures exceptional structural integrity, providing robust resistance to external pressure, impact, and tensile forces. All matching silencing fittings are produced via precision injection molding, with dimensional parameters perfectly calibrated to the solid wall spiral pipe for tight, leak-proof connections. The product adopts a bonded connection method, which enhances sealing performance and ensures the overall integrity of the drainage system. Rigorously tested in CNAS laboratories, the pipe exhibits excellent resistance to acids, alkalis, and corrosion, making it suitable for handling various drainage types—including domestic wastewater, rainwater, and mild industrial fluids. The smooth inner surface of the solid wall prevents scaling and sediment accumulation, maintaining low fluid resistance and reducing the risk of blockages over long-term use. Whether installed in indoor spaces or underground applications, PVC-U Solid Wall Spiral Pipe delivers reliable, efficient, and quiet drainage performance.

| Performance Advantage

Exceptional Noise Reduction: The internal spiral structure guides water to form a wall-attached flow, minimizing impact and turbulence. When paired with silencing fittings, it significantly reduces drainage noise, making it ideal for noise-sensitive environments such as residential buildings, hotels, and hospitals.

High Drainage Efficiency: The spiral flow pattern increases water velocity and improves drainage capacity compared to traditional solid-wall pipes. It effectively handles large flow rates, reducing the risk of waterlogging in both indoor and outdoor applications.

Superior Mechanical Strength: The solid wall construction combined with internal spiral reinforcement provides excellent resistance to pressure, impact, and tensile forces. It can withstand underground soil loads, construction impacts, and long-term fluid pressure without deformation.

Cost-Saving Integration: The pipe integrates drainage and ventilation functions into a single system, eliminating the need for additional ventilation pipes and fittings. This reduces material costs, simplifies installation, and lowers overall construction expenses.

Durable Corrosion Resistance: High-quality PVC-U resin offers outstanding resistance to acids, alkalis, and various corrosive substances. It maintains stable performance in harsh environments such as municipal sewage and mild industrial drainage, with a service life far exceeding that of steel pipes.

Lightweight and Easy Installation: With a density of 1/5 to 1/6 that of steel pipes, the product is lightweight and easy to transport and handle. The bonded connection method and precise fitting compatibility simplify on-site installation, shortening the construction period and reducing labor intensity.

Anti-Scaling and Anti-Blockage: The smooth inner surface of the solid wall prevents scaling and sediment accumulation. The spiral flow helps flush away debris, maintaining low fluid resistance and minimizing maintenance requirements.

Application

PVC-U Solid Wall Spiral Pipe is widely used in various construction and drainage scenarios due to its comprehensive performance advantages, including:

Residential Buildings: High-end apartments, villas, and residential complexes. The noise reduction feature ensures a quiet living environment, while efficient drainage meets household and community needs.

Commercial and Public Buildings: Shopping malls, hotels, hospitals, office buildings, and stadiums. It adapts to complex layouts and large drainage demands, providing reliable support for public areas, restrooms, and utility spaces.

Municipal Engineering: Urban drainage networks, siphon rainwater systems, road and bridge drainage, and municipal sewage transportation. Its high mechanical strength and corrosion resistance withstand harsh underground conditions.

Industrial Facilities: Manufacturing plants, industrial parks, and workshops with mild corrosive drainage. It safely transports industrial wastewater and process fluids without degradation.

Renovation Projects: Upgrades and reconstructions of old building drainage systems. The lightweight design minimizes damage to existing structures, while improving drainage efficiency and noise reduction.
