Our PVC-U drain pipe series represents innovation in drainage technology and has earned widespread acclaim both domestically and internationally. These products boast an extraordinary lifespan and unmatched corrosion resistance when compared to traditional cast iron pipes. During construction, they offer the benefits of being lightweight, easy to handle, and straightforward to install and connect. As a result, they find extensive use in a wide array of applications, including civil building drainage and sewage, chemical waste management, and efficient rainwater drainage systems. Furthermore, our PVC-U drainage pipes and fittings strictly adhere to the highest standards as per GB/T5836.1-2018 and GB/T5836.2-2018, ensuring unparalleled quality and performance.
Featuring versatility in design, our product line comes in three distinctive forms: straight pipe, expanded pipe, and expanded pipe. Each can utilize various pipe connection techniques tailored to specific project needs. Beyond standard offerings, we have engineered specialized pressure drainage pipes for rainwater management as well as architecturally pleasing square rain downspouts, ideal for diverse rainwater drainage designs and construction projects. Additionally, our advanced line includes innovative drainage solutions like the spiral silencer, hollow spiral silencer, and hollow wall silencer, all designed with the purpose of effectively minimizing drainage noise, thereby enhancing the ambiance of any environment.

Features
★ Our pipes boast an outstanding surface hardness and remarkable tensile strength, ensuring a high safety factor for every pipeline.
★ With impressive aging resistance, our pipes have an exceptional service life, reaching up to more than 50 years.
★ These pipes excel in corrosion resistance against inorganic acids, alkalis, and salts, making them ideal for industrial wastewater discharge and transportation.
★ Experience smooth water flow with our pipes' low friction coefficient, which minimizes clogging and reduces maintenance workloads.
★ Enjoy the benefits of a high oxygen index and self-extinguishing performance, providing added safety and reliability.
★ With a minimal linear expansion coefficient of 0.07mm/m.ºC, our pipes exhibit negligible deformation from temperature changes. They offer better frost resistance compared to cast iron drainage pipes.
★ Achieve high installation efficiency with our simple and convenient pipe and fitting bonding process.
★ Perfect for industrial and civil building drainage projects, our pipes handle continuous domestic sewage up to 40ºC and instant discharges up to 80ºC, suitable for non-corrosive industrial wastewater.
Pipe Connection
★ Follow strict procedures for pipe socket connections to ensure optimal results:
1. Before bonding, thoroughly clean both the pipe socket and fitting socket.
2. Accurately measure the socket depth and clearly mark the pipe port for precision.
3. Apply adhesive by thoroughly painting the socket first, then the pipe, ensuring a uniform and appropriate coating.
4. Align and insert the pipe in one motion to the marked point, rotating by 1/4 turn for secure bonding.
5. Remove any excess adhesive from the socket carefully.
6. Allow the bonded pipe to stand until its interface is fully cured for maximum strength.
★ Adhere to the following for safe adhesive use:
1. Use adhesives and cleaning agents judiciously and restrict access to trained personnel.
2. Maintain good ventilation at bonding sites and eliminate any open flames.
3. Avoid construction below -10ºC and refrain from using fire for bonding point curing.
4. Equip construction personnel with gloves; if adhesive contacts eyes, rinse with plenty of water and seek medical attention immediately.
Installation Instructions
Saw Pipe and Groove:
Determine the length of the saw pipe by layering based on precise measurements and each connected fitting's dimensions. Use fine tooth saws, cutters, or pipe-cutting machines for clean cuts with no deformations. File the socket section into a 15°-30° groove, maintaining a length of at least 3mm and a thickness of 1/3 to 1/2 of the pipe wall. Remove debris post-grooving for a clean finish.
Socket Protection:
Post-connection, cleanse excess adhesive with cotton yarn or a dry cloth lightly dipped in acetone or similar detergents. Let the joint cure static, considering adhesive performance and weather conditions. Extend curing time during winter for optimal results.
