Our PVC-U drain pipe collection represents a pinnacle of advanced drainage technology, extensively acclaimed and utilized both domestically and internationally. These pipes offer an outstanding lifespan and resistance to corrosion, qualities that traditional cast iron pipes simply cannot match. During construction, these pipes shine with their lightweight nature, simplifying handling, installation, and connection processes. They find extensive use in residential and commercial building drainage systems, including sewage and chemical waste management, as well as rainwater drainage applications. Our PVC-U drainage pipes and fittings are crafted to align with the stringent standards of GB/T5836.1-2018 and GB/T5836.2-2018.
This versatile product line is available in three configurations: straight pipe, expanded straight pipe, and expanded pipe, accommodating various pipe connection techniques. Furthermore, we have pioneered pressure drainage pipes specifically designed for efficient rainwater management and aesthetically pleasing square rain downspouts to integrate seamlessly into diverse architectural rainwater drainage systems. Our innovative silencing drainage pipes, including the spiral silencer, hollow spiral silencer, and hollow wall silencer, are engineered to significantly minimize drainage noise, enhancing the overall user experience.

★ Engineered with high oxygen index material, our PVC fittings boast superior self-extinguishing capabilities, enhancing safety and reliability.
★ Featuring a minimal linear expansion coefficient of just 0.07mm/m.ºC, our pipes maintain form with negligible temperature-induced distortion, superior thermal conductivity, and frost resistance, outperforming cast iron drainage options.
★ With easy bonding connections, our pipes ensure straightforward construction and convenient operation, enhancing installation efficiency remarkably.
★ Perfect for both industrial and civil applications, our PVC fittings support indoor and outdoor drainage projects, managing wastewater up to 40ºC and instantaneous discharges up to 80ºC—ideal for non-corrosive industrial waste.
Pipe connection
★ Ensure the integrity of your pipe socket connections by meticulously following this step-by-step guide:
1. Start by thoroughly cleaning both the pipe socket and pipe fitting socket before beginning the bonding process.
2. Accurately measure the socket depth and mark the pipe port for precise alignment.
3. Apply the adhesive meticulously: coat the socket first, then the pipe, ensuring an even and ample application.
4. Align correctly, insert to the marked depth in one fluid motion, and give a 1/4 turn to secure the fit.
5. Immediately clean any excess adhesive from the surface of the socket.
6. Allow the bonded pipes to stand undisturbed until the bond has fully cured.
★ For optimal safety, adhere to the following adhesive usage guidelines:
1. Use adhesives and cleaning agents judiciously, restricting access to non-operators to prevent mishaps.
2. Maintain a flame-free environment at the bonding site and ensure adequate ventilation at all times.
3. Avoid construction in temperatures below -10ºC, and refrain from using fire to dry adhesive points.
4. Equip construction staff with gloves for protection. If adhesive enters the eyes, rinse thoroughly with water and seek medical attention immediately.
Installation instructions
Saw pipe and groove:
Determine saw pipe lengths per measurement, selecting tools like fine tooth saws or pipe cutting machines for precision. Ensure clean cuts with no deformations. File pipe ends to a 15°-30° groove, at least 3mm long and 1/3-1/2 pipe wall thick. Remove debris post-groove for optimal bonding.
Socket protection:
Post-connection, clean any extruded adhesive with acetone-dipped cloth, letting it cure statically as per adhesive type and weather. Extend curing time in colder conditions.
