Our PVC-U Drain Pipe represents an evolution in drainage solutions, boasting a proven technology embraced globally. These pipes promise exceptional longevity and resistance to corrosion, making them a superior choice over traditional cast iron pipes. The construction advantages are evident with their lightweight nature and ease of handling, installation, and connection. This versatility makes them ideal for a wide array of applications, including civil building drainage and sewage, chemical waste management, and efficient rainwater drainage systems. Each pipe and fitting meets the rigorous standards of GB/T5836.1-2018 and GB/T5836.2-2018, ensuring quality and reliability.
Our product line offers a range of configurations including straight pipes, expanded pipes, and even more flexible expanded options. These can be connected using various methods to suit specific project needs. Additionally, we've innovated with pressure drainage systems specifically designed for effective rainwater management across diverse architectural designs. Our unique offerings also include aesthetically pleasing square rain downspouts, and we've engineered a suite of drainpipes like spiral silencers, hollow spiral silencers, and hollow wall silencers, all aimed at minimizing drainage noise and enhancing the tranquility of living and working spaces.

Features
★ Discover the exceptional surface hardness and tensile strength of our Long-Lasting PVC Pipe Fitting, ensuring a high safety factor for your pipeline systems.
★ Benefit from superior aging resistance with a service life extending beyond 50 years, a testament to our commitment to durability and longevity.
★ Experience unparalleled corrosion resistance against inorganic acids, alkalies, and salts, perfect for industrial sewage discharge and efficient transportation.
★ Enjoy a smooth water flow thanks to a low friction coefficient, reducing blockages and minimizing maintenance — ensuring less workload and more productivity.
★ Achieve peace of mind with high oxygen index materials that offer self-extinguishing properties for enhanced safety.
★ With a minimal linear expansion coefficient of just 0.07mm/m.ºC, expect reduced temperature-induced deformation, alongside superior frost resistance compared to traditional cast iron drainage pipes.
★ Simplify your installations with easy-to-bond connections between pipes and fittings, boosting construction simplicity, operational convenience, and installation efficiency.
★ Ideal for indoor and outdoor drainage in both industrial and civil constructions, our pipes handle continuous domestic sewage up to 40ºC, withstanding instant discharges up to 80ºC. They are also suitable for industrial wastewater that doesn't corrode the pipe.
Pipe connection
★ Follow these meticulous procedures for a perfect pipe socket connection:
1. Ensure both the pipe socket and fitting socket are impeccably clean before bonding.
2. Accurately measure the depth and mark the pipe port for precision.
3. Apply adhesive methodically, starting with the socket and then the fitting, ensuring a uniform and adequate coat.
4. Align accurately, insert into the mark in one motion, and rotate 1/4 turn for a secure fit.
5. Clean any excess adhesive from the socket for a neat finish.
6. Allow the bonded pipe to stand until the interface is fully cured for optimal strength.
★ Ensure safe adhesive usage by adhering to these guidelines:
1. Only trained operators should handle adhesives and cleaning agents to maintain safety standards.
2. Maintain good ventilation and avoid open flames near the bonding area for a risk-free environment.
3. Avoid construction below -10ºC and refrain from using fire to dry the adhesive point.
4. Construction personnel should wear gloves, and if adhesive contacts the eyes, flush immediately with water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length precisely according to measurements and connected fittings’ dimensions. Use fine tooth saws, cutters, or pipe cutting machines for even cuts. Ensure a flat fracture with no deformation, and file the socket area into a 15°-30° groove, not less than 3mm in length, with a groove thickness of 1/3-1/2 the wall thickness. Clean debris thoroughly post-grooving.
Socket protection:
After connecting the socket, cleanse any extruded adhesive meticulously using cotton yarn or a dry cloth with a mild detergent like acetone. Allow static curing of the interface based on adhesive performance and climate conditions. Extend curing time appropriately during winter construction for optimal results.
