Introducing our PVC-U Drain Pipe Series, a marvel in drainage technology that has gained global recognition for its superior performance. These pipes boast an impressive lifespan and corrosion resistance that far exceeds cast iron pipes. Their lightweight nature makes them easy to handle, install, and connect, a highly sought-after feature in both residential and commercial construction. Perfectly suited for civil building drainage, sewage systems, chemical waste drainage, and effective rainwater management, these pipes are a staple in various applications. The PVC-U drainage pipes and fittings proudly comply with the rigorous standards of GB/T5836.1-2018 and GB/T5836.2-2018, ensuring top-notch quality and reliability.
Our product range includes three versatile forms: straight pipe, expanded pipe, and double expanded pipe, each offering multiple connection methods to suit diverse needs. Furthermore, we've expanded our product line to include high-pressure drainage pipes specifically designed for efficient rainwater management, alongside our aesthetically pleasing square rain downspouts crafted for architectural elegance in various building designs. Additionally, we've innovated a series of noise-reducing drainage pipes, such as the spiral silencer, hollow spiral silencer, and hollow wall silencer, all engineered to minimize disruptive drainage noise effectively.

Pipe connection
★ For optimal results, adhere strictly to the following pipe socket connection procedures:
1. Thoroughly clean both the pipe socket and fitting before applying any bonding agent.
2. Precisely measure and mark the depth of the socket on the pipe port to ensure accuracy.
3. Apply adhesive evenly, starting with the socket, followed by the pipe socket, for a uniform coat.
4. Carefully align and insert into the marked depth, then rotate 1/4 turn to secure.
5. Remove any excess adhesive from the socket surface for a clean finish.
6. Allow the bonded pipe to stand undisturbed until the joint is fully cured.
★ Ensure safety with adhesives by following these critical precautions:
1. Use adhesives and cleaning agents responsibly, restrict to trained operators only.
2. Maintain a flame-free environment at bonding sites with excellent ventilation.
3. Avoid construction below -10ºC; never use fire to accelerate adhesive curing.
4. Construction personnel should wear gloves; in case of eye contact, rinse with water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine saw pipe length from measured dimensions per layer, using fine-tooth saws or cutting machines. Ensure cuts are smooth, free from deformation. File socket ends into a 15°-30° groove, maintaining a depth of 1/3-1/2 pipe wall thickness, ensuring debris removal post-grooving.
Socket protection:
After socket connection, clean excess adhesive with cotton or dry cloth and detergent. Allow curing based on adhesive properties and climate, extending time for winter projects.
