Our PVC-U drain pipes represent a pinnacle of innovation in plumbing technology, boasting a well-established reputation both domestically and internationally. These products offer unparalleled benefits, including an extraordinary lifespan and superior corrosion resistance compared to traditional cast iron pipes. During construction, their lightweight structure ensures effortless handling, while their design facilitates straightforward installation and seamless connection. Extensively utilized across a wide range of applications, they are ideal for civil building drainage and sewage, chemical drainage and sewage systems, as well as rainwater management solutions. Our PVC-U drainage pipe and fittings adhere to the stringent quality standards set by GB/T5836.1-2018 and GB/T5836.2-2018.
The versatility of our product line is highlighted by three distinct forms: straight pipe, expanded pipe, and expanded pipe variants, accommodating various pipe connection methods to suit diverse needs. Additionally, we've pioneered advanced pressure drainage pipes specifically for efficient rainwater management, complemented by aesthetically pleasing square rain downspouts that enhance architectural designs. For environments requiring noise reduction, our innovative range includes spiral silencers, hollow spiral silencers, and hollow wall silencers, engineered to significantly diminish drainage noise, ensuring a quieter, more peaceful environment.

Features
★ Experience unmatched durability with pipes that boast exceptional surface hardness and tensile strength, ensuring a high safety factor for all your plumbing needs.
★ Enjoy peace of mind with superior aging resistance, as these robust fittings are built to last, offering a remarkable service life of over 50 years.
★ Embrace the versatility of pipelines with excellent resistance to corrosion from inorganic acids, alkalis, and salts, making them ideal for industrial sewage discharge and transport.
★ Benefit from low friction coefficients that guarantee smooth water flow, reducing the risk of blockages and minimizing maintenance efforts.
★ Feel secure with materials that exhibit a high oxygen index and self-extinguishing capabilities, enhancing overall safety.
★ Appreciate the minimal linear expansion coefficient of 0.07mm/m.ºC, with limited temperature-induced deformation, along with smaller thermal conductivity and elastic modulus, offering superior frost resistance compared to traditional cast iron pipes.
★ Enjoy seamless installations with easy-to-bond pipe and fitting connections, making construction simple and efficient with elevated installation productivity.
★ Ideal for both industrial and civil building drainage systems, these pipelines can handle domestic sewage temperatures up to 40ºC continuously and up to 80ºC for short bursts, while safely managing non-corrosive industrial wastewater.
Pipe connection
★ Expertly execute pipe socket connections by adhering meticulously to these essential procedures:
1. Ensure the cleanliness of both pipe socket and fitting socket before applying bonding agents.
2. Accurately measure the socket depth and mark the pipe port precisely.
3. Apply the adhesive first to the socket, followed by the socket, ensuring an even and adequate coating for best results.
4. Skillfully align and insert the pipe into the marked section in one seamless motion, accompanied by a gentle 1/4 rotation.
5. Carefully clean away any excess adhesive from the socket to maintain a neat finish.
6. Allow the bonded pipe to stand until the interface is fully cured, ensuring robust and reliable connections.
★ Prioritize safety in adhesive application with adherence to these critical guidelines:
1. Use adhesives and cleaning agents responsibly, restricting access to trained personnel only.
2. Prohibit open flames near bonding areas and maintain good ventilation to ensure a safe working environment.
3. Avoid construction activities in temperatures below -10ºC, and refrain from using fire to dry adhesive points.
4. Equip construction teams with gloves and have safety measures in place. In case of accidental contact with eyes, rinse with ample water immediately and seek medical attention.
Installation instructions
Saw pipe and groove:
The precise length of the saw pipe is determined incrementally, considering the specific measurements and dimensions of each connected fitting. Choose fine tooth saws, cutters, or pipe cutting machines for precision. Ensure clean, even cuts without deforming the section. File the socket portion into a 15°-30° groove using a medium board file, ensuring a groove length of no less than 3mm. The groove depth should be 1/3 to 1/2 of the pipe wall thickness, with thorough debris removal post-grooving.
Socket protection:
After socket connection, cleanse any extruded adhesive using cotton yarn or dry cloth with a touch of acetone or similar detergent. Allow it to remain static until fully cured, considering adhesive performance and climate conditions. Extend curing time during winter construction as necessary to ensure reliability.
