Delve into the excellence of our PVC-U drain pipe, a sophisticated line of drainage solutions with a time-tested technology footprint. Embraced globally, these pipes stand tall with attributes of extraordinary longevity and exceptional resistance to corrosion, a feat where cast iron pipes can't compete. When it comes to construction, our pipes shine with their feather-light weight, effortless handling, seamless installation, and versatile connectivity. Their utility stretches across multiple domains including civil building drainage, sewage management, chemical waste discharge, and efficient rainwater diversion. Each pipe and fitting in our PVC-U drainage series adheres strictly to the rigorous standards of GB/T5836.1-2018 and GB/T5836.2-2018, ensuring top-notch quality and reliability.
Our product range is remarkably diverse, featuring three distinct forms: straight pipes, expanded pipes, and sophisticated expanded pipes, all capable of accommodating various pipe connection methodologies. Innovatively designed pressure drainage pipes cater specifically to efficient rainwater management, complemented by our aesthetically pleasing square rain downspouts, tailored for diverse architectural designs and engineering projects. Our advanced drainage solutions also include specialized pipes such as the spiral silencer, hollow spiral silencer, and hollow wall silencer, all crafted meticulously to minimize drainage noise and enhance the tranquility of your environment.

Features
★ Experience the exceptional surface hardness and tensile strength of our pipes, ensuring a high safety factor for your pipelines.
★ Witness unparalleled aging resistance that extends the normal service life of our pipes to over 50 years, standing the test of time.
★ Enjoy outstanding corrosion resistance against inorganic acid, alkali, and salt, making our pipelines ideal for industrial sewage discharge and transportation.
★ Benefit from a low friction coefficient for smooth water flow, minimizing blockages and reducing maintenance efforts significantly.
★ Our material boasts a high oxygen index and remarkable self-extinguishing performance for enhanced safety.
★ With a small linear expansion coefficient of 0.07mm/m.ºC, minimal thermal deformation, excellent thermal conductivity, and elastic modulus, our pipes offer superior frost resistance compared to cast iron drainage pipes.
★ Enjoy the simplicity and convenience of pipe and pipe fitting connections that can be easily bonded, leading to high installation efficiency.
★ Perfectly suited for both industrial and civil building drainage projects, accommodating continuous domestic sewage discharge up to 40ºC, and instant sewage discharge up to 80ºC. Also compatible with non-corrosive industrial wastewater.
Pipe connection
★ For optimal results, ensure pipe socket connections follow these meticulous procedures:
1. Thoroughly clean the pipe socket and fitting socket before bonding to ensure a secure connection.
2. Precisely measure the socket depth and mark the pipe port for accurate alignment.
3. Apply the adhesive uniformly, starting with the socket, followed by the pipe, ensuring even coverage.
4. Align the directions carefully, insert into the marked part in one swift motion, and rotate by 1/4 turn for a secure connection.
5. Clean any excess adhesive from the socket for a neat finish.
6. Allow the bonded pipe to stand until the interface has fully cured, ensuring a robust join.
★ Adhere to these safety guidelines for adhesive use to ensure optimal safety:
1. Use adhesives and cleaning agents responsibly, restricting use to trained operators only.
2. Maintain good ventilation and ensure no open flames are near the bonding point.
3. Avoid construction below -10ºC, and never use fire to bake the adhesive point.
4. Equip construction personnel with gloves, and if adhesive contacts the eyes, rinse immediately with ample water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length based on precise measurements and connected pipe fitting dimensions. Choose fine tooth saws, cutters, or pipe cutting machines for sawing. Ensure a flat fracture and avoid deformation. File the socket part into a 15°-30° groove, at least 3mm long and 1/3-1/2 of the pipe wall thickness. After grooving, remove all debris for a clean finish.
Socket protection:
Post-connection, clean any extruded adhesive using cotton yarn or dry cloth with a bit of detergent like acetone. Allow the connection to cure statically, adjusting time based on adhesive properties and climate conditions. Extend curing times appropriately for winter constructions.
