Our PVC-U drain pipes represent a pinnacle of advanced technology, widely recognized and utilized both domestically and internationally. These pipes boast exceptional longevity and corrosion resistance, attributes unmatched by traditional cast iron alternatives. Their lightweight construction ensures effortless handling, installation, and connection. They are extensively employed in various sectors, including civil building drainage, sewage systems, chemical drainage, and rainwater management. Our PVC-U drain pipes and fittings adhere strictly to the GB/T5836.1-2018 and GB/T5836.2-2018 standards.
We offer our products in three versatile forms: straight pipe, expanded pipe, and expanded pipe. These can be connected using various methods, catering to diverse needs. Additionally, we have innovatively developed pressure drainage pipes specifically for rainwater management and aesthetically pleasing square rain downspouts, tailored for different building designs and engineering requirements. Our product range includes specialized drainage solutions such as spiral silencers, hollow spiral silencers, and hollow wall silencers, all meticulously engineered to minimize drainage noise.

Features
★ The surface hardness and tensile strength of the pipe are excellent, ensuring a high pipeline safety factor.
★ Exceptional aging resistance, with a normal service life exceeding 50 years.
★ Superior corrosion resistance to inorganic acids, alkalis, and salts, making it ideal for industrial sewage discharge and transportation.
★ Low friction coefficient ensures smooth water flow, reduces the likelihood of clogs, and minimizes maintenance workload.
★ High oxygen index and self-extinguishing performance enhance safety.
★ Small linear expansion coefficient of 0.07mm/m.ºC minimizes deformation due to temperature changes. Better frost resistance compared to cast iron drainage pipes.
★ Easy and efficient installation with simple bonding methods for pipe and fittings connections.
★ Suitable for indoor and outdoor drainage projects in industrial and civil buildings. Can handle domestic sewage with continuous discharge temperatures up to 40ºC and instant discharge up to 80ºC, as well as industrial wastewater that does not corrode the pipe.
Pipe Connection
★ Follow these precise steps for pipe socket connection:
1. Ensure pipe socket and fitting socket are clean before bonding.
2. Measure socket depth and mark the pipe port accordingly.
3. Apply adhesive evenly: coat the socket first, then the pipe.
4. Align and insert into marked position in one go, then rotate a 1/4 turn.
5. Wipe off any excess adhesive from the socket.
6. Allow the bonded pipe to stand until the interface is fully cured.
★ Adhere to these safety guidelines when using adhesives:
1. Use adhesives and cleaning agents as needed; restrict use to trained operators.
2. Ensure no open flames are present and maintain good ventilation at the bonding site.
3. Avoid construction below -10ºC and do not use fire to dry adhesive points.
4. Construction personnel must wear gloves. In case of accidental contact with eyes, rinse thoroughly with water and seek medical attention immediately.
Installation Instructions
Saw Pipe and Groove:
Determine the length of the saw pipe based on measured dimensions and connected fittings. Use fine tooth saws, cutters, or pipe cutting machines. Ensure the cut is flat without deforming the section. File a 15°-30° groove at the socket end for adhesion. Groove length should be at least 3mm, with a thickness of 1/3-1/2 of the pipe wall. Clean debris after grooving.
Socket Protection:
After socket connection, clean excess adhesive with cotton yarn or a cloth dipped in a mild detergent like acetone. Let it stand until the adhesive cures, considering the performance and climate conditions. Extend curing time during winter construction.
