PVC-U drain pipes are a groundbreaking series of drainage solutions that have transformed the industry both domestically and internationally. These pipes boast unrivaled longevity and exceptional corrosion resistance, qualities that far surpass traditional cast iron pipes, making them a standout choice in the market. Their lightweight design ensures easy handling, streamlined installation, and effortless connections, making them indispensable across various sectors. Ideal for residential and commercial building drainage, sewage systems, chemical drainage, and rainwater management, these pipes are versatile and extraordinarily reliable. Moreover, our PVC-U drainage pipes and fittings adhere strictly to the rigorous standards of GB/T5836.1-2018 and GB/T5836.2-2018, guaranteeing unparalleled quality and performance.
Our pipes are available in three distinct forms: straight pipe, expanded pipe, and expanded pipe variants, offering flexibility in application and connection methods. Additionally, we have innovated with pressure drainage pipes designed specifically for efficient rainwater management and aesthetically pleasing square rain downspouts tailored to diverse architectural needs. Our advanced range also includes various noise-reducing drainage solutions such as spiral silencers, hollow spiral silencers, and hollow wall silencers, all engineered to minimize drainage noise, thereby enhancing the comfort and tranquility of any environment.
Product Parameters

Features
★ Our High Pressure PVC Pipe Fittings offer unparalleled surface hardness and tensile strength, delivering an exceptional safety factor for your advanced pipeline systems.
★ Engineered for durability, these pipes exhibit extraordinary aging resistance, ensuring a reliable service life that surpasses 50 years.
★ The fittings' excellent corrosion resistance against inorganic acids, alkalis, and salts makes them perfect for industrial sewage discharge and transportation needs.
★ With a low friction coefficient, our pipes guarantee smooth water flow, significantly reducing the risk of clogging and minimizing maintenance requirements.
★ The material not only has a high oxygen index but also boasts superior self-extinguishing properties, enhancing safety.
★ Minimal linear expansion coefficient of just 0.07mm/m.ºC ensures that our pipes experience negligible deformation due to temperature changes. Their low thermal conductivity and elastic modulus provide remarkable frost resistance, outperforming cast iron drainage pipes.
★ The design allows for easy bonding of pipe and fitting connections, making the construction process straightforward and highly efficient.
★ Ideal for both indoor and outdoor drainage projects in industrial and civil buildings, our fittings can handle continuous domestic sewage temperatures up to 40ºC, withstanding instant discharge temperatures up to 80ºC. Perfect for non-corrosive industrial wastewater applications.
Pipe Connection
★ Follow these steps for optimal pipe socket connections:
1. Ensure that both the pipe socket and the fitting socket are thoroughly clean before bonding.
2. Measure the socket depth and mark the corresponding depth on the pipe port.
3. Apply adhesive evenly, beginning with the socket and then moving to the fitting socket.
4. Align and insert the pipe into the marked section in one continuous motion, then rotate it by 1/4 turn.
5. Wipe away any excess adhesive from the socket to maintain a clean bond.
6. Allow the bonded pipe to stand undisturbed until the interface is fully cured.
★ Safety guidelines to follow when using adhesives:
1. Use adhesives and cleaning agents as needed and ensure they are handled exclusively by trained personnel.
2. Ensure proper ventilation and keep bonding areas free from open flames.
3. Avoid construction in temperatures below -10ºC and refrain from using fire to expedite the curing process.
4. Workers should wear protective gloves. In case of adhesive contact with eyes, rinse immediately with water and seek medical attention.
Installation Instructions
Saw Pipe and Groove:
The length of the sawed pipe should be based on precise measurements and the dimensions of each connected fitting. Utilize 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 for optimal connection.
Socket Protection:
After making the socket connection, clean any extruded adhesive using a cloth dipped in a mild detergent such as acetone. Allow the joint to cure according to the adhesive's performance and prevailing weather conditions, extending the curing time appropriately during winter constructions.
