Introducing the PVC-U Drain Pipe series—a product line with proven technology that has achieved widespread acclaim both domestically and internationally. These pipes boast a remarkable longevity and resistance to corrosion that cast iron pipes simply can't match. During construction, they are favored for their lightweight nature, ease of handling, and seamless installation and connection capabilities. This makes them an ideal choice for a myriad of applications, including civil building drainage and sewage systems, chemical waste disposal, and even rainwater management. Furthermore, every PVC-U drainage pipe and fitting is crafted to meet the stringent standards set by GB/T5836.1-2018 and GB/T5836.2-2018, ensuring you receive nothing but the finest quality.
Our product versatility shines with three distinct forms: straight pipes, expanded pipes, and further enhanced expanded pipes. Each form supports various connection methods, offering flexibility for any project. Beyond standard offerings, our innovative pressure drainage pipes cater to rainwater management needs, while the elegantly designed square rain downspouts complement any architectural style. We have also engineered a range of sound-reducing drainage solutions, including spiral silencers, hollow spiral silencers, and hollow wall silencers, each meticulously designed to minimize noise during drainage operations. Trust us to not only meet but exceed your drainage requirements with our cutting-edge solutions.

Features
★ Experience a new level of durability with our PVC pipes that boast superior surface hardness and tensile strength. Enjoy peace of mind with a high pipeline safety factor, ensuring reliable performance.
★ Invest in longevity with our pipes, offering outstanding aging resistance for a service life that extends beyond 50 years. It's a long-lasting solution you can trust.
★ Our pipes excel in resisting corrosion from inorganic acids, alkalis, and salts, making them ideal for industrial sewage discharge and transportation. Choose the reliable solution for tough environments.
★ With a low friction coefficient, our pipelines ensure a smooth water flow, minimizing the risk of blockages and reducing maintenance demands. Experience efficiency at its finest.
★ Benefit from the high oxygen index and self-extinguishing properties of our material, enhancing pipeline safety and performance.
★ Enjoy minimal thermal deformation with a small linear expansion coefficient of 0.07mm/m.ºC. Our pipes' low thermal conductivity and elastic modulus provide superior frost resistance compared to cast iron drainage pipes.
★ Simplify your project with easy bonding of pipes and fittings. Our construction method is straightforward, operation is convenient, and installation efficiency is maximized.
★ Perfect for both industrial and civil building drainage projects, our pipelines handle continuous domestic sewage up to 40ºC and instantaneous discharges up to 80ºC. They are suitable for industrial wastewater that does not corrode the pipe, ensuring versatility.
Pipe connection
★ Ensure a secure pipe socket connection by adhering to these meticulous procedures:
1. Prior to bonding, meticulously clean both the pipe socket and fitting socket to ensure a perfect fit.
2. Accurately measure and mark the depth of the socket to guarantee a precise insertion.
3. Apply adhesive correctly, starting with the socket and then the fitting, ensuring an even and appropriate coating for optimal bonding.
4. Align pieces perfectly; insert confidently to the marked point and rotate a smooth 1/4 turn for a secure fit.
5. Clean off any excess adhesive from the socket to maintain a tidy and professional finish.
6. Allow the bonded pipe to stand undisturbed until the interface is fully cured, ensuring a robust connection.
★ Always prioritize safety with adhesives by following these vital guidelines:
1. Use adhesives and cleaning agents only as needed, restricting access to trained personnel to ensure safety.
2. Maintain a flame-free environment at bonding sites with proper ventilation to prevent hazards.
3. Avoid construction in temperatures below -10ºC and never use fire to bake adhesive points, preserving both safety and integrity.
4. Equip construction personnel with gloves for protection. In case of eye contact with adhesive, rinse thoroughly with water and seek immediate medical attention.
Installation instructions
Saw pipe and groove:
Determine each layer's saw pipe length based on precise measurements and fitting dimensions. Use fine-tooth saws, cutters, or pipe cutting machines for smooth cuts. Ensure no deformation at the section, and file the socket's glue area into a 15°-30° groove, with a length no less than 3mm and a depth of 1/3-1/2 of the pipe wall. Clean debris after grooving.
Socket protection:
After socket connection, clean extruded adhesive with a dry cloth or cotton dipped in detergent like acetone. Allow the joint to cure based on adhesive performance and climate, extending curing time during winter.
