Our PVC-U drain pipe series boasts a mature technology that has been embraced both domestically and internationally. These pipes offer unmatched advantages over traditional cast iron pipes, including exceptional longevity and superior corrosion resistance. In construction, they stand out due to their lightweight nature, ease of handling, simple installation, and seamless connection. This versatility makes them ideal for a wide range of applications, including civil building drainage and sewage systems, chemical drainage, rainwater drainage, and more. Our PVC-U drainage 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 lineup includes three distinct types: straight pipes, expanded pipes, and expanded pipes with varied connection methods. Additionally, we've innovated with pressure drainage pipes tailored for rainwater systems, and aesthetically pleasing square downspouts designed for diverse architectural needs. To further enhance functionality, we've developed a series of specialized drainage pipes, such as spiral silencers, hollow spiral silencers, and hollow wall silencers, all engineered to significantly reduce drainage noise. These advanced solutions cater to the unique requirements of modern drainage design and engineering.

Features
★ Boasting exceptional surface hardness and tensile strength, these pipes ensure a high safety factor for robust and reliable applications.
★ With outstanding aging resistance, our pipes offer a remarkable service life that extends beyond 50 years.
★ The pipes exhibit superb corrosion resistance against inorganic acids, alkalis, and salts, making them ideal for industrial sewage discharge and transport.
★ A low friction coefficient guarantees smooth water flow, minimizing blockages and reducing maintenance efforts.
★ High oxygen index and self-extinguishing capabilities enhance the safety profile of our materials.
★ With a minimal linear expansion coefficient of 0.07mm/m.ºC, the pipes experience negligible deformation due to temperature changes. Their low thermal conductivity and elastic modulus also ensure superior frost resistance compared to cast iron drainage pipes.
★ The pipes and fittings are easy to bond, ensuring a straightforward construction process, convenient operation, and high installation efficiency.
★ Perfect for both industrial and civil building drainage systems, our pipes can handle continuous discharge of domestic sewage at temperatures up to 40ºC and instant discharge up to 80ºC. They are also suitable for industrial wastewater that does not corrode the pipes.
Pipe Connection
★ To ensure proper socket connections, follow these precise steps:
1. Clean both the pipe socket and pipe fitting socket thoroughly before bonding.
2. Measure the socket depth and mark the pipe port accordingly.
3. Apply adhesive evenly, starting with the socket and moving to the pipe, ensuring a uniform coating.
4. Align the pipes, insert them into the marked section in one go, and twist 1/4 turn.
5. Wipe away any excess adhesive from the socket.
6. Allow the bonded pipe to stand until the interface is fully cured.
★ Ensure safe use of adhesives by adhering to these guidelines:
1. Use adhesives and cleaning agents only as needed; unauthorized individuals should not handle them.
2. Avoid open flames at the bonding site, and ensure proper ventilation.
3. Do not conduct bonding operations below -10ºC, and never use fire to accelerate curing.
4. Equip construction personnel with gloves. In case of eye contact with adhesive, flush with water immediately and seek medical attention.
Installation Instructions
Saw Pipe and Groove:
Measure the length of each pipe segment layer by layer, accounting for the dimensions of all connected fittings. Use fine tooth saws, cutters, or pipe cutting machines to ensure clean, deformation-free cuts. The socket section to be glued should be filed into a 15°-30° groove with a medium board file, maintaining a groove length of at least 3mm and a depth of 1/3-1/2 of the pipe wall thickness. Remove any debris after filing.
Socket Protection:
After socket connection, clean off extruded adhesive with cotton yarn or a dry cloth lightly moistened with a detergent like acetone. Allow the joint to remain static until fully cured, adjusting curing time for winter conditions as necessary.
