PVC-U drain pipes represent the pinnacle of modern drainage solutions, seamlessly blending durability with cutting-edge technology. These pipes are celebrated for their exceptional longevity and unmatched resistance to corrosion, a quality that significantly surpasses traditional cast iron alternatives. Their lightweight design ensures effortless handling, simplified installation, and seamless connections, making them indispensable across a wide range of applications. Perfect for residential and commercial drainage systems, sewage networks, chemical waste management, and rainwater collection, these pipes are the epitome of versatility and dependability. Furthermore, our PVC-U drainage pipes and fittings adhere strictly to the stringent standards of GB/T5836.1-2018 and GB/T5836.2-2018, guaranteeing premier quality and superior performance.
Our pipes are available in three distinct configurations: straight pipe, expanded pipe, and their respective variants, offering unparalleled flexibility in application and connection. We have also introduced innovative pressure drainage pipes crafted specifically for optimal rainwater management, alongside aesthetically designed square rain downspouts that complement various architectural styles. Our state-of-the-art collection includes an array of noise-reducing drainage solutions, such as spiral silencers, hollow spiral silencers, and hollow wall silencers. These advanced features are meticulously engineered to minimize drainage noise, thereby enhancing environmental comfort and tranquility.
Product Parameters

Features
★ Our superior PVC fittings feature enhanced surface hardness and exceptional tensile strength, ensuring the utmost reliability and safety for your pipeline system.
★ Boasting remarkable aging resistance, our pipes have a standard service life exceeding an impressive 50 years.
★ Exceptional corrosion resistance against inorganic acids, alkalis, and salts makes these fittings the ideal choice for industrial sewage discharge and transportation.
★ With a low friction coefficient, our pipes ensure smooth water flow, significantly reducing clogging and minimizing maintenance efforts.
★ The high oxygen index and excellent self-extinguishing properties of our materials ensure superior safety.
★ Featuring a minimal linear expansion coefficient of just 0.07mm/m.ºC, our pipes exhibit negligible deformation even with temperature changes. Their low thermal conductivity and elastic modulus offer outstanding frost resistance, surpassing that of cast iron drainage pipes.
★ Our pipe and fitting connections are easily bonded, simplifying the construction process and ensuring high efficiency.
★ Perfect for both indoor and outdoor drainage projects in industrial and civil buildings, our pipes can handle continuous domestic sewage temperatures up to 40ºC and instant discharge temperatures up to 80ºC, making them ideal for non-corrosive industrial wastewater applications.
Pipe Connection
★ Follow these steps for optimal pipe socket connections:
1. Ensure both the pipe socket and fitting socket are thoroughly clean before bonding.
2. Measure the socket depth and mark the pipe port for accuracy.
3. Apply adhesive uniformly, starting with the socket and then the fitting socket.
4. Align the pipe and insert it into the marked section in one motion, then rotate it 1/4 turn.
5. Wipe away any excess adhesive from the socket area.
6. Allow the bonded pipe to stand until the interface is fully cured for optimal results.
★ Adhere to these safety guidelines when using adhesives:
1. Handle adhesives and cleaning agents only with trained personnel, and use them as needed.
2. Ensure proper ventilation and keep bonding areas free of open flames.
3. Avoid construction in temperatures below -10ºC and refrain from using fire to speed up the curing process.
4. Workers should wear protective gloves. If adhesive contacts the eyes, rinse immediately with water and seek medical attention.
Installation Instructions
Saw Pipe and Groove:
Determine the sawed pipe length based on precise measurements and the dimensions of each connected fitting. Use fine-tooth saws, cutters, or pipe cutting machines to ensure a clean, flat cut without deformation. Groove the socket area to be glued at a 15°-30° angle using a medium board file, ensuring a groove length of at least 3mm and a thickness of 1/3-1/2 of the pipe wall. Remove all debris after grooving to ensure a clean surface.
Socket Protection:
After socket connection, clean any extruded adhesive using a cloth dipped in a mild detergent such as acetone. Allow the joint to cure based on adhesive performance and weather conditions, extending curing time as needed for winter construction.
