Our PVC-U drain pipe collection represents a pinnacle of engineering excellence, offering a tried-and-true solution for your drainage needs, both domestically and internationally. These pipes excel with their exceptional durability and corrosion resistance that outmatches traditional cast iron pipes. Designed with construction efficiency in mind, our pipes are lightweight, ensuring effortless handling, smooth installation, and seamless connectivity. Perfectly suited for a wide array of applications, our PVC-U pipes are ideal for civil building drainage and sewage systems, chemical waste management, and rainwater drainage, among others. Notably, all our PVC-U drainage pipes and fittings adhere strictly to the rigorous standards specified in GB/T5836.1-2018 and GB/T5836.2-2018.
Our product lineup features three distinct forms: straight pipes, expanded pipes, and expanded pipes with specialty functions, alongside a versatile range of connection methods to suit your specific requirements. Further, we've innovated with our pressure drainage pipes tailored for rainwater systems and aesthetically pleasing square rain downspouts, designed for seamless integration into diverse architectural projects. To enhance your experience, we offer an array of noise-reducing drainage solutions, such as our spiral silencer, hollow spiral silencer, and hollow wall silencer series, effectively minimizing drainage noise and elevating the tranquility of your environment.

Outstanding Features
★ Showcasing remarkable surface hardness and tensile strength, our pipes ensure a superior safety factor for any pipeline application.
★ With exceptional resistance to aging, our products boast a lifespan exceeding 50 glorious years.
★ These pipelines exhibit unparalleled corrosion resistance against inorganic acids, alkalis, and salts, perfectly suited for the efficient discharge and transport of industrial sewage.
★ Experience the smooth, uninterrupted flow of water thanks to the pipeline's minimal friction coefficient, reducing the likelihood of blockages and minimizing maintenance efforts.
★ Engineered with materials holding a high oxygen index, our pipes demonstrate superior self-extinguishing properties.
★ Enjoy minimal deformation due to temperature variations, courtesy of the pipeline's small linear expansion coefficient of 0.07mm/m.ºC. Combined with low thermal conductivity and elastic modulus, this ensures better frost resistance than cast iron pipes.
★ The pipe and fittings connection process is straightforward and convenient, enhancing installation efficiency through simple bonding techniques.
★ Ideal for both industrial and civil building drainage projects, these pipelines handle continuous domestic sewage discharge temperatures up to 40ºC and instantaneous temperatures up to 80ºC, including industrial wastewater that does not corrode the pipe.
Efficient Pipe Connection
★ For optimal results, adhere strictly to these socket connection procedures:
1. Ensure the pipe socket and fitting socket are thoroughly cleaned prior to bonding.
2. Accurately measure the socket depth and mark the pipe accordingly.
3. Apply adhesive, beginning with the socket, followed by the pipe, ensuring even distribution of the coating.
4. Align properly, insert the pipe swiftly to the marked point, and rotate it by 1/4 turn.
5. Remove any excess adhesive from the socket immediately.
6. Allow the bonded pipe to stand until the interface has fully cured.
★ Adhere to these safety guidelines when using adhesives:
1. Use adhesives and cleaners as needed and restrict usage to authorized personnel only.
2. Ensure no open flames are present at bonding sites, and maintain proper ventilation.
3. Avoid construction at temperatures below -10ºC, and do not expose adhesive points to direct fire.
4. Workers should wear protective gloves. If adhesive contacts the eyes, rinse immediately with copious amounts of water and seek medical attention.
Comprehensive Installation Instructions
Precision Sawing and Grooving:
Precisely determine the saw pipe length based on meticulous measurements and the dimensions of connected fittings. Use fine-tooth saws, cutters, or pipe cutting machines to ensure a flat cut without section deformation. File the glue socket into a 15°-30° groove, with a depth of at least 3mm and thickness of 1/3 to 1/2 of the wall. Clear any debris post-grooving.
Ensuring Socket Protection:
Post-connection, cleanse residual adhesive with cotton or a cloth moistened with a gentle detergent like acetone. Allow the interface to cure according to adhesive properties and climate conditions, extending curing time in winter as needed.
