Our PVC-U drain pipes represent the pinnacle of drainage solutions, setting new standards both locally and globally. Crafted for unmatched durability and exceptional corrosion resistance, these pipes outlast traditional cast iron options. Their lightweight design facilitates effortless handling, streamlined installation, and easy connections, essential for a multitude of applications. Perfect for residential and commercial drainage, sewage systems, chemical waste disposal, and rainwater management, these pipes offer versatility and dependability. Adhering to the stringent specifications of GB/T5836.1-2018 and GB/T5836.2-2018, our PVC-U drainage pipes and fittings guarantee superior quality and performance.
Available in three versatile forms—straight pipe, expanded pipe, and expanded pipe variants—our pipes offer flexible application and connection methods. We've also pioneered pressure drainage pipes for optimized rainwater management and architecturally appealing square rain downspouts for diverse building aesthetics. Our innovative range includes noise-reducing drainage solutions like spiral silencers, hollow spiral silencers, and hollow wall silencers, all engineered to significantly lower drainage noise, enhancing comfort and serenity in any environment.
Product Parameters

Features
★ Our PVC fittings feature exceptional surface hardness and tensile strength, ensuring an unparalleled safety factor for your pipeline system.
★ With extraordinary aging resistance, our pipes guarantee a remarkable service life exceeding 50 years.
★ Exceptional corrosion resistance against inorganic acids, alkalis, and salts makes our fittings perfect for industrial sewage discharge and transportation.
★ A low friction coefficient ensures smooth water flow, minimizes clogging, and greatly reduces maintenance efforts.
★ Boasting a high oxygen index and outstanding self-extinguishing properties, our material offers superior 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 exceptional frost resistance, surpassing cast iron drainage pipes.
★ Easy bonding of pipe and fitting connections ensures a straightforward and highly efficient construction process.
★ 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. They are ideal for non-corrosive industrial wastewater applications.
Pipe Connection
★ Follow these meticulous steps for optimal pipe socket connections:
1. Ensure both the pipe socket and fitting socket are clean prior to bonding.
2. Measure the socket depth and mark the pipe port accordingly for precision.
3. Apply adhesive uniformly, beginning with the socket and then the fitting socket.
4. Align and insert the pipe into the marked section in one smooth motion, then rotate 1/4 turn.
5. Wipe away any excess adhesive from the socket to ensure a clean finish.
6. Allow the bonded pipe to stand undisturbed until the interface is fully cured.
★ Adhere to these essential safety guidelines when using adhesives:
1. Use adhesives and cleaning agents as required, ensuring they are handled exclusively by trained personnel.
2. Maintain proper ventilation and ensure bonding areas are free of open flames.
3. Avoid construction in temperatures below -10ºC and do not use fire to expedite the curing process.
4. Workers should wear gloves. If adhesive contacts the eyes, rinse immediately with water and seek medical attention promptly.
Installation Instructions
Saw Pipe and Groove:
The sawed pipe length should be 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. The socket area to be glued should be grooved 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. Thoroughly remove all debris 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.
