Our PVC-U Drain Pipe series stands as a testament to advanced technology, gaining widespread acclaim both domestically and internationally. These pipes boast a longevity and corrosion resistance that outclasses traditional cast iron alternatives. In construction, they shine with features like lightweight design, ease of handling, and seamless installation. Their versatility makes them perfect for civil building drainage, sewage systems, chemical waste management, and rainwater drainage projects. Our PVC-U drain pipes and fittings strictly adhere to the GB/T5836.1-2018 and GB/T5836.2-2018 standards, ensuring top-notch quality and reliability.
Our product range includes three distinguished forms: straight pipes, expanded pipes, and further expanded pipes, accommodating various pipe connection methods. Beyond these, we offer specialized pressure drainage pipes for efficient rainwater management and aesthetically pleasing square rain downspouts tailored for diverse architectural needs. We've also pioneered a series of advanced drainage solutions such as spiral silencers, hollow spiral silencers, and hollow wall silencers designed to significantly minimize drainage noise. These innovations cater to the unique requirements of any building's rainwater management and drainage infrastructure.

Features
★ The surface hardness and tensile strength of our Lightweight PVC Fittings are outstanding, ensuring a high safety factor for your pipeline installations.
★ Featuring excellent aging resistance, our pipes boast a service life that can exceed 50 years, providing long-term reliability.
★ With superior corrosion resistance to inorganic acids, alkalis, and salts, these pipes are ideal for industrial sewage discharge and transportation.
★ The low friction coefficient ensures smooth water flow, reducing the likelihood of blockages and minimizing maintenance efforts.
★ Crafted from materials with a high oxygen index, these pipes offer impressive self-extinguishing properties for enhanced safety.
★ The linear expansion coefficient of just 0.07mm/m.ºC minimizes deformation due to temperature changes. Additionally, the small thermal conductivity and elastic modulus provide exceptional frost resistance compared to cast iron drainage pipes.
★ Easy installation is guaranteed through the bonding connection method, simplifying the construction process and boosting installation efficiency.
★ Suitable for both industrial and civil building drainage projects, our pipes can handle continuous domestic sewage at temperatures up to 40ºC and instant sewage discharges up to 80ºC. They are also resistant to non-corrosive industrial wastewater.
Pipe Connection
★ When connecting pipes via sockets, please follow these meticulous steps:
1. Ensure both the pipe socket and fitting socket are clean before beginning the bonding process.
2. Measure the depth of the socket and mark the corresponding depth on the pipe.
3. Apply adhesive, starting with the socket and then the pipe, ensuring an even and adequate coating.
4. Align the pipe and fitting correctly, insert up to the marked depth in one go, and rotate 1/4 turn for a secure fit.
5. Wipe away any excess adhesive from the socket for a clean finish.
6. Allow the bonded pipe to stand undisturbed until the joint is fully cured.
★ For safe use of adhesives, adhere to the following guidelines:
1. Only use adhesives and cleaning agents as needed. They should not be handled by untrained personnel.
2. Ensure there are no open flames near the bonding area and maintain good ventilation.
3. Avoid construction at temperatures below -10ºC and never use fire to speed up the curing process.
4. Construction personnel should wear gloves. In case of adhesive contact with the eyes, rinse immediately with plenty of water and seek medical attention.
Installation Instructions
Saw Pipe and Groove:
Determine the length of the saw pipe based on precise measurements and the dimensions of each connecting pipe fitting layer by layer. Use fine-tooth saws, cutters, or pipe cutting machines for smooth cuts. Ensure the cut section is flat and free from deformation. File the socket area to a 15°-30° groove, with a length no less than 3mm and groove depth 1/3 to 1/2 of the pipe wall thickness. Remove any debris post-grooving.
Socket Protection:
After socket connection, clean the extruded adhesive with cotton yarn or a dry cloth dipped in a mild detergent like acetone. Allow the joint to cure statically, adjusting curing time based on adhesive performance and weather conditions, especially extending the time during winter construction.
