PVC-U drain pipe represents a cutting-edge innovation in plumbing technology, widely embraced both domestically and internationally. These pipes offer an extraordinary lifespan and unmatched resistance to corrosion, setting them apart from traditional cast iron alternatives. Their lightweight nature ensures effortless handling, while their simple installation and connection make them a preferred choice across various applications. From civil building drainage and sewage systems to chemical and rainwater drainage, these pipes excel in all areas. Moreover, PVC-U drainage pipes and fittings proudly conform to the rigorous standards set by GB/T5836.1-2018 and GB/T5836.2-2018, ensuring top-notch performance and reliability.
Our product line boasts three distinct pipe forms: straight pipe, expanded pipe, and expanded pipe variations, offering versatile connection methods to suit diverse needs. Beyond this, our company has pioneered the development of pressure drainage pipes specifically designed for efficient rainwater management. We also offer aesthetically pleasing square rain downspouts tailored for various architectural designs and engineering projects. To further enhance user experience, we have engineered an innovative series of drainage pipes, including spiral silencers, hollow spiral silencers, and hollow wall silencers, which significantly minimize drainage noise, providing a quieter and more serene environment.

★ Perfect for drainage projects in industrial and civil buildings, these pipes handle continuous domestic sewage up to 40ºC and instant discharges up to 80ºC, along with non-corrosive industrial wastewater.
Pipe connection
★ Ensure secure socket connections by following these meticulous procedures:
1. Begin by cleansing the pipe socket and fitting socket to prepare for a seamless bonding process.
2. Carefully measure the socket depth and mark the pipe accordingly to ensure precision.
3. Apply adhesive evenly, starting with the socket, followed by the pipe, ensuring a uniform coat throughout.
4. Align and insert the pipe into the marked position, then rotate a quarter turn for a perfect fit.
5. Remove any excess adhesive from the socket to maintain a clean and efficient joint.
6. Allow the bonded pipe to stand until the interface is completely cured, securing a lasting connection.
★ Ensure adhesive safety by adhering to the following guidelines:
1. Only operators should handle adhesives and cleaning agents, ensuring controlled usage.
2. Maintain excellent ventilation and avoid open flames at the bonding site for safety.
3. Avoid construction in temperatures below -10ºC and refrain from using fire to heat adhesive points.
4. Equip personnel with gloves, and if adhesive enters the eyes, rinse immediately with water and seek medical attention.
Installation instructions
Saw pipe and groove:
The pipe length is precisely determined layer by layer based on exact measurements and the dimensions of each fitting. Choose fine tooth saws, cutters, or pipe cutting machines for clean cuts without deformation. Prepare the socket area for bonding by creating a 15°-30° groove using a medium board file; the groove should be no less than 3mm and 1/3-1/2 the pipe wall thickness. Clean away debris post-groove completion for optimal adhesion.
Socket protection:
After connecting, cleanse the extruded adhesive with cotton yarn or a dry cloth moistened with a mild solvent like acetone. Allow the joint to set until cured, adjusting curing time for winter conditions as needed.
