Presenting our state-of-the-art PVC-U Drain Pipe Collection—a testament to technological excellence and reliability. With a history of proven performance both domestically and internationally, these pipes offer a lifespan and resistance to corrosion that stands unmatched by traditional cast iron alternatives. Engineered for construction ease, they boast a lightweight design, facilitating effortless handling, installation, and connection, making them a top choice for civil building drainage, sewage systems, chemical waste management, and rainwater management. Our PVC-U drainage solutions strictly conform to the high standards of GB/T5836.1-2018 and GB/T5836.2-2018, ensuring top-notch quality and performance.
Our product line features three distinct formats: straight pipe, expanded pipe, and further expanded pipe, all adaptable to an array of connection techniques. In addition, we offer innovative pressure drainage pipes tailored for efficient rainwater management, alongside aesthetically pleasing square rain downspouts, meticulously designed for diverse architectural engineering. To address acoustic concerns, we have developed a series of drainage pipes including spiral silencers, hollow spiral silencers, and hollow wall silencers, dedicated to minimizing drainage noise and enhancing the overall environmental experience.

Features
★Our PVC pipes boast exceptional surface hardness and tensile strength, ensuring a high safety factor for all your pipeline applications.
★With superior aging resistance, our pipes promise a remarkable service life extending beyond 50 years, maintaining performance over decades.
★Impressive corrosion resistance against inorganic acids, alkalis, and salts makes our pipeline ideal for handling industrial sewage and transport.
★A low friction coefficient ensures smooth water flow, reduces clogging, and minimizes maintenance efforts, offering peace of mind.
★Featuring a high oxygen index, our material is self-extinguishing, enhancing safety in various applications.
★With a minimal linear expansion coefficient of 0.07mm/m.ºC, our pipes exhibit negligible temperature-induced deformation, superior frost resistance, and maintain elasticity, outperforming traditional cast iron drainage pipes.
★Pipe and fitting connections can be easily bonded, simplifying construction, enhancing convenience, and maximizing installation efficiency.
★Perfect for industrial and civil indoor and outdoor drainage projects, our pipes handle domestic sewage continuously at temperatures up to 40ºC and intermittently up to 80ºC, suitable for non-corrosive industrial wastewater.
Pipe connection
★Ensure precise pipe socket connections by following these meticulous procedures:
1. Clean both the pipe socket and fitting socket thoroughly before bonding for a secure fit.
2. Accurately measure and mark the depth of the socket on the pipe port.
3. Apply adhesive carefully, starting with the socket and then the spigot, ensuring an even and adequate coating.
4. Align correctly, insert swiftly to the marked depth, and rotate 1/4 turn for a perfect bond.
5. Clean any excess adhesive from the socket for a neat finish.
6. Allow the bonded pipes to stand undisturbed until fully cured, ensuring lasting durability.
★Adhere to these safety guidelines for using adhesives:
1. Utilize adhesives and cleaning agents responsibly; restrict use to trained operators only.
2. Ensure good ventilation and eliminate open flames at bonding sites for safety.
3. Avoid construction below -10ºC and never use fire to dry adhesive points.
4. Wear protective gloves during construction; in case of eye contact with adhesive, rinse immediately with water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine saw pipe lengths based on precise measurements and connected fitting dimensions. Utilize fine tooth saws, cutters, or pipe cutting machines for a clean cut, ensuring no deformation. Create a 15°-30° groove on the socket area using a medium board file. The groove should be at least 3mm long, with thickness 1/3-1/2 of the pipe wall. Clean away debris after grooving for optimal adhesive bonding.
Socket protection:
Post-connection, clean excess adhesive with cotton yarn or dry cloth soaked in a mild solvent like acetone. Stabilize until the adhesive cures, considering weather conditions, with extended curing time during winter.
