PVC-U drain pipe is a series of technologically advanced drain pipe products that have achieved global acclaim. These pipes boast a remarkable lifespan and exceptional corrosion resistance, far surpassing that of traditional cast iron pipes. Designed for ease of use, they are lightweight, simplifying transport, installation, and connection, making them the prime choice for a wide range of applications. Utilized extensively in civil building drainage and sewage systems, chemical drainage, sewage, and rainwater management, PVC-U drainage pipes and fittings adhere to the rigorous standards of GB/T5836.1-2018 and GB/T5836.2-2018.
Our product range includes straight pipes, expanded pipes, and uniquely designed expanded pipes that offer versatile connection methods. Additionally, we've innovated pressure drainage pipes specifically for rainwater management, complemented by aesthetically pleasing square rain downspouts for various architectural designs. Our pioneering series includes drainage solutions like spiral silencers, hollow spiral silencers, and hollow wall silencers, all engineered to significantly reduce noise, ensuring a quieter and more serene environment in any setting.

Features
★ Experience superior quality with pipes boasting exceptional surface hardness and tensile strength, ensuring a high pipeline safety factor that stands the test of time.
★ With outstanding aging resistance, our pipelines offer a remarkable service life exceeding 50 years, promising enduring reliability.
★ Our pipelines exhibit exceptional corrosion resistance against inorganic acids, alkalis, and salts, making them ideal for industrial sewage discharge and transportation needs.
★ Featuring a low friction coefficient, our pipelines provide smooth water flow, significantly reducing the risk of clogs and minimizing maintenance efforts.
★ Crafted from materials with a high oxygen index, our pipes possess self-extinguishing properties, enhancing safety measures.
★ With a minimal linear expansion coefficient of 0.07mm/m.ºC, our pipelines are less susceptible to temperature-induced deformation, offering superior thermal conductivity and elastic modulus, and better frost resistance compared to cast iron drainage pipes.
★ Our pipe and pipe fittings effortlessly bond together, simplifying construction methods for convenient operation and maximizing installation efficiency.
★ Perfect for industrial and civil building projects, our drainage pipelines manage indoor and outdoor discharge seamlessly. They handle domestic sewage continuously at temperatures up to 40ºC and can withstand instant sewage discharge up to 80ºC, provided the wastewater doesn't corrode the pipes.
Pipe connection
★ To ensure secure pipe socket connections, adhere strictly to the outlined procedures for optimal results:
1. Begin by thoroughly cleaning both the pipe socket and fitting socket before initiating the bonding process.
2. Accurately measure the socket depth and mark the pipe port for precise alignment.
3. Carefully apply adhesive, starting with the socket and then the fitting, ensuring an even and adequate coat.
4. Align the pipes in the intended direction, insert into the marked section in one motion, and rotate 1/4 turn for a secure fit.
5. Clean any excess adhesive from the socket to maintain a neat finish.
6. Allow the bonded pipe to stand undisturbed until the interface is fully cured, ensuring a strong and lasting connection.
★ Adhere to the following guidelines for safe adhesive use, ensuring a secure and hazard-free environment:
1. Use adhesives and cleaning agents judiciously, restricting access to non-operators to maintain safety.
2. Ensure the bonding area is free from open flames and well-ventilated to prevent any potential hazards.
3. Avoid construction at temperatures below -10ºC, and do not use fire to hasten adhesive curing.
4. Equip construction personnel with gloves, and in case of accidental eye contact with adhesive, rinse immediately with ample water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine saw pipe lengths according to precise layer measurements and dimensions of each connected fitting. Use fine-tooth saws, cutters, or pipe-cutting machines. Ensure cuts are flat and free from deformation. File the socket area to a 15°-30° groove, with a length not less than 3mm and a thickness of 1/3-1/2 of the pipe wall. Clear debris post-groove completion.
Socket protection:
After socket connection, clean excess adhesive using cotton yarn or a dry cloth with a mild detergent like acetone. Allow the joint to remain static until cured, based on adhesive performance and weather conditions. Extend curing time appropriately in winter.
