Our PVC-U drain pipe series represent the pinnacle of maturity in technology, boasting extensive utilization across domestic and international landscapes. These products offer exceptional benefits including unmatched longevity and corrosion resistance, outstripping traditional cast iron pipes. With features like lightweight construction, ease of handling, and simple installation and connection, they are indispensable in a multitude of applications: from civil building drainage and sewage systems to chemical and rainwater drainage. Each PVC-U drainage pipe and fitting adheres strictly to the rigorous standards of GB/T5836.1-2018 and GB/T5836.2-2018.
Available in three distinct forms-straight pipe, expanded pipe, and expanded pipe-our products support a variety of pipe connection methods. Furthermore, we have innovated pressure drainage pipes specifically designed for efficient rainwater management along with elegant square rain downspouts for diverse architectural needs. To combat drainage noise, we've developed an impressive array of specialized drainage pipes, including spiral silencers, hollow spiral silencers, and hollow wall silencers, ensuring peace and quiet in every drainage operation.

Unmatched Features
★ Exceptional surface hardness and tensile strength, ensuring a high pipeline safety factor.
★ Outstanding aging resistance, promising a reliable service life of over 50 years.
★ Exceptional corrosion resistance to inorganic acids, alkalis, and salts, making it ideal for industrial sewage discharge and transportation.
★ Low friction coefficient ensures smooth water flow, reduces clogging, and minimizes maintenance workload.
★ High oxygen index material with self-extinguishing properties.
★ Low linear expansion coefficient (0.07mm/m.ºC), minimal deformation due to temperature. Superior thermal conductivity and elastic modulus compared to cast iron drainage pipes, enhancing frost resistance.
★ Simple and efficient pipe and fitting bonding process, ensuring high installation efficiency.
★ Ideal for both industrial and civil indoor and outdoor drainage projects. Suitable for continuous domestic sewage discharge (up to 40ºC) and instant sewage discharge (up to 80ºC), as well as non-corrosive industrial wastewater.
Expert Pipe Connection Guide
★ Follow these procedures for effective pipe socket connections:
1. Clean the pipe socket and fitting socket thoroughly before bonding.
2. Measure the socket depth and mark the pipe accordingly.
3. Apply adhesive evenly, painting the socket first, followed by the fitting socket.
4. Align and insert into the marked part with a single motion, then rotate 1/4 turn.
5. Wipe off any excess adhesive from the socket.
6. Allow the bonded pipe to stand until the interface is fully cured.
★ Adhere to these safety guidelines when using adhesives:
1. Only operators should use adhesives and cleaning agents as needed.
2. Ensure good ventilation and avoid open flames at the bonding site.
3. Avoid construction below -10ºC and do not use fire to dry adhesive points.
4. Wear gloves during application. In case of eye contact with adhesive, rinse immediately with plenty of water and seek medical attention.
Comprehensive Installation Instructions
Precision Sawing and Grooving:
Determine saw pipe length based on measurements and connected fitting dimensions. Use fine-tooth saws, cutters, or pipe cutting machines for precision. Ensure a flat cut with no deformation. File socket area for bonding into a 15°-30° groove, at least 3mm long and 1/3-1/2 pipe wall thickness. Clean debris post-grooving.
Socket Protection:
Clean extruded adhesive with cotton yarn or dry cloth dipped in detergent (e.g., acetone) after socket connection. Allow curing based on adhesive performance and climate. Extend curing time during winter.
