Our PVC-U Drain Pipe series stands as a testament to advanced engineering and innovative technology, having earned a reputation for excellence both domestically and internationally. These pipes offer unmatched longevity and superb corrosion resistance, setting them apart from traditional cast iron pipes. When it comes to construction, they shine with their lightweight structure which makes handling, installation, and connection a breeze. They are the go-to choice for applications in civil building drainage and sewage systems, as well as chemical drainage, sewage, and rainwater drainage. Our PVC-U drainage pipes and fittings strictly adhere to the rigorous standard requirements of GB/T5836.1-2018 and GB/T5836.2-2018.
Our product line features versatile options including straight pipes, expanded pipes, and expanded pipes, all compatible with a variety of pipe connection methods. To cater to diverse architectural needs, we have innovated with pressure drainage pipes suited for rainwater management, along with aesthetically pleasing square rain downspouts for tailored rainwater drainage solutions in various building designs and projects. Furthermore, we have developed a sophisticated range of drainage pipes—featuring spiral silencers, hollow spiral silencers, and hollow wall silencers—all crafted to significantly minimize drainage noise, thus enhancing the overall experience.

Features
★ Experience the uncompromised excellence of our pipe's surface hardness and tensile strength, ensuring a high safety factor for any pipeline.
★ Boasting superior aging resistance, this pipe promises a remarkable service life exceeding 50 years, providing enduring reliability.
★ Perfectly engineered for superior corrosion resistance against inorganic acids, alkalis, and salts, making it ideal for industrial sewage discharge and transportation needs.
★ With a low friction coefficient, enjoy smooth water flow with minimal plugging risks, reducing maintenance efforts significantly.
★ Crafted from material with an impressively high oxygen index, it offers outstanding self-extinguishing performance.
★ Minimal linear expansion coefficient of 0.07mm/m.ºC ensures temperature-induced deformation is negligible. Its low thermal conductivity and elastic modulus offer superior frost resistance compared to cast iron pipes.
★ Enjoy the convenience of bonded connections between pipes and fittings, facilitating a straightforward construction process and exceptional installation efficiency.
★ Ideally suited for industrial and civil building drainage projects both indoors and outdoors. Perfect for continuously discharging domestic sewage at temperatures below 40ºC or instant discharges up to 80ºC. Also suitable for industrial wastewater that does not corrode the pipe.
Pipe connection
★ Ensure pipe socket connections are meticulously performed by following these essential procedures:
1. Thoroughly clean both the pipe socket and pipe fitting socket prior to bonding.
2. Accurately measure the socket depth and clearly mark the pipe port.
3. Apply adhesive carefully: first to the socket, then to the pipe, ensuring an even and appropriate coating.
4. Align direction precisely, insert to the marked part in one swift motion, and rotate 1/4 turn for optimal results.
5. Clean any adhesive residue from the socket for a pristine finish.
6. Allow the bonded pipe to stand until the interface has fully cured.
★ Adhere to the following safety guidelines when using adhesives:
1. Use adhesives and cleaning agents judiciously; non-operators should avoid handling.
2. Ensure no open flames are present at the bonding site and maintain excellent ventilation.
3. Avoid constructing below -10ºC; do not fire-cure the adhesive point.
4. Construction personnel should be equipped with gloves. In case adhesive contacts eyes, flush with copious water and seek medical attention immediately.
Installation instructions
Saw pipe and groove:
Determine the length of the saw pipe layer by layer, based on accurate measurements and dimensions of connected fittings. Opt for fine tooth saws, cutters, or pipe cutting machines for clean cuts. Ensure a flat fracture with no deformation. File the socket to a 15°-30° groove with a medium board file, making sure the groove is no less than 3mm long and 1/3-1/2 of the pipe wall thickness. Remove debris once grooving is complete.
Socket protection:
Post-connection, clean the extruded adhesive using cotton yarn or dry cloth slightly moistened with acetone or similar detergent. Let it remain static until the interface cures as per the adhesive’s properties and weather conditions. Extend curing time for winter construction appropriately.
