Our cutting-edge PVC-U drain pipe series stands as a testament to advanced technology and engineering excellence, boasting supremely mature technology that has been embraced both nationally and internationally. These pipes offer a lifespan and resistance to corrosion that is simply unmatched by traditional cast iron counterparts. In construction and civil engineering, our PVC-U pipes shine with attributes such as lightweight composition, effortless handling, straightforward installation, and seamless connectivity. They have become the go-to choice for a plethora of applications, including residential and industrial drainage, sewage management, and the efficient handling of rainwater. Additionally, these pipes and fittings are fully compliant with the comprehensive standards defined in GB/T5836.1-2018 and GB/T5836.2-2018.
Our product range is versatile, featuring three distinct forms: straight pipes, expanded pipes, and further expanded configurations, offering multiple connection methods to suit diverse needs. Moreover, we've innovated pressure drainage pipes specifically tailored for optimal rainwater drainage. Adding to this, our aesthetically pleasing square rain downspouts are designed to enhance rainwater management in architectural projects. To combat noise pollution, we have developed an array of specialized drainage solutions, including spiral silencers, hollow spiral silencers, and hollow wall silencers, each engineered to significantly diminish drainage noise, ensuring a serene environment.

Features
★ Experience unparalleled durability with our pipes, boasting superior surface hardness and tensile strength, ensuring a high safety factor for your pipeline.
★ Benefit from exceptional aging resistance; our pipes are designed to have a normal service life extending beyond 50 years, providing long-lasting reliability.
★ With outstanding corrosion resistance to inorganic acids, alkalis, and salts, these pipes are perfect for industrial sewage discharge and transportation.
★ The low friction coefficient ensures smooth water flow, minimizing blockage risks and reducing maintenance efforts.
★ Featuring a high oxygen index, our material delivers remarkable self-extinguishing performance for enhanced safety.
★ With a minimal linear expansion coefficient of 0.07mm/m.ºC, our pipes exhibit minor deformation due to temperature changes. They offer superior frost resistance compared to cast iron drainage pipes, thanks to low thermal conductivity and elastic modulus.
★ Enjoy the simplicity and convenience of bonded connections for pipes and fittings, facilitating a highly efficient installation process.
★ Ideal for both industrial and civil building indoor and outdoor drainage projects, our pipes handle continuous domestic sewage discharge at temperatures up to 40ºC and instant sewage discharge up to 80ºC, including industrial wastewater that is non-corrosive to the pipe.
Pipe connection
★ Ensure flawless pipe socket connections by strictly adhering to the following procedures:
1. Begin by meticulously cleaning the pipe socket and fitting socket before bonding.
2. Accurately measure the socket depth and mark the pipe appropriately.
3. Apply the adhesive carefully, starting with the socket, followed by the pipe, ensuring uniform and proper coverage.
4. Align precisely, insert into the marked area in one motion, and rotate 1/4 turn for a secure fit.
5. Thoroughly wipe away any excess adhesive from the socket.
6. Allow the bonded pipe to stand until the interface is completely cured.
★ Adhere to the following guidelines for the safe use of adhesives:
1. Use adhesives and cleaning agents only as required; they should not be handled by non-operators.
2. Ensure no open flames near the bonding site and maintain good ventilation.
3. Avoid construction below -10ºC, and do not use fire to dry adhesive points.
4. Equip construction personnel with gloves; if adhesive contacts the eyes, rinse immediately with plenty of water and seek medical help.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length meticulously layer by layer based on precise measurements and the dimensions of each connected fitting. Choose fine-tooth saws, cutters, or pipe-cutting machines for accurate cuts. Ensure fractures are flat and sections remain undeformed. File the socket part to be glued into a 15°-30° groove with a medium board file, with a groove length not less than 3mm and thickness 1/3-1/2 of the pipe wall. Clear debris post-grooving.
Socket protection:
After connecting the socket, gently scrub away any extruded adhesive with cotton yarn or a dry cloth dampened with a mild detergent like acetone. Let the assembly stand undisturbed until the interface is cured in alignment with adhesive performance and climatic conditions. Extend curing time appropriately for winter construction.
