Our innovative PVC-U drain pipes represent the pinnacle of modern drainage solutions, having set a new benchmark in the industry both domestically and globally. These pipes offer unparalleled longevity and exceptional resistance to corrosion, significantly outperforming traditional cast iron alternatives. Their lightweight structure ensures effortless handling, streamlined installation, and seamless connections, making them an invaluable asset across various sectors. Perfectly suited for residential and commercial drainage, sewage systems, chemical drainage, and efficient rainwater management, these pipes are synonymous with versatility and reliability. Moreover, our PVC-U drainage pipes and fittings are meticulously crafted to meet the stringent standards of GB/T5836.1-2018 and GB/T5836.2-2018, guaranteeing superior quality and exceptional performance.
Our high-performance pipes are available in three distinct formats: straight pipe, expanded pipe, and expanded pipe variants, providing unmatched flexibility in application and connection. We have further innovated with pressure drainage pipes designed for optimal rainwater management and stylish square rain downspouts that cater to diverse architectural requirements. Additionally, our advanced product lineup includes various noise-reducing drainage solutions such as spiral silencers, hollow spiral silencers, and hollow wall silencers. These are expertly engineered to minimize drainage noise, significantly enhancing environmental comfort and tranquility.
Product Parameters

Features
★ Our PVC fittings are crafted with exceptional surface hardness and tensile strength, ensuring a robust safety factor for your entire pipeline system.
★ Boasting outstanding aging resistance, our pipes deliver a reliable service life that surpasses 50 years.
★ These fittings offer superior corrosion resistance against inorganic acids, alkalis, and salts, making them the perfect choice for industrial sewage discharge and transportation.
★ Featuring a low friction coefficient, our pipes ensure smooth water flow, reduce the risk of clogging, and minimize maintenance requirements.
★ The material has an impressive high oxygen index and excellent self-extinguishing properties, ensuring enhanced safety.
★ With a minimal linear expansion coefficient of 0.07mm/m.ºC, our pipes exhibit negligible temperature-induced deformation. Their low thermal conductivity and elastic modulus provide superior frost resistance compared to cast iron drainage pipes.
★ Pipe and fitting connections are easily bonded, simplifying the construction process and enhancing efficiency.
★ Ideal for both indoor and outdoor drainage projects in industrial and civil buildings, our pipes handle continuous domestic sewage temperatures up to 40ºC and instant discharge temperatures up to 80ºC, making them perfect 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 clean before applying adhesive.
2. Measure the socket depth and mark the pipe port accordingly to ensure a precise fit.
3. Apply adhesive uniformly, starting with the socket and then the fitting socket for an even bond.
4. Align and insert the pipe into the marked section in one fluid motion, then rotate 1/4 turn to secure.
5. Wipe away any excess adhesive from the socket to maintain a clean finish.
6. Allow the bonded pipe to stand until the interface is fully cured for maximum strength.
★ Adhere to these safety guidelines when using adhesives:
1. Use adhesives and cleaning agents as needed, ensuring handling is done by trained personnel only.
2. Maintain proper ventilation and ensure bonding areas are free of open flames for safety.
3. Avoid construction in temperatures below -10ºC and never use fire to accelerate the curing process.
4. Workers should wear gloves for protection. 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 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, with a groove length of at least 3mm and a thickness of 1/3-1/2 of the pipe wall. Ensure all debris is removed after grooving.
Socket Protection:
After socket connection, clean any extruded adhesive with a cloth dipped in a mild detergent like acetone. Allow the joint to cure based on adhesive performance and weather conditions, extending curing time appropriately for winter constructions.
