The PVC-U drain pipe series is an innovation in drainage technology, renowned for its widespread usage both domestically and internationally. These exceptional pipes offer a lifespan and corrosion resistance that cast iron pipes simply cannot match. Their lightweight nature simplifies handling, installation, and connection, making them a preferred choice in diverse applications such as civil building drainage, sewage systems, chemical waste management, and rainwater collection. Our PVC-U drainage pipes and fittings are crafted to meet and exceed the rigorous standards set by GB/T5836.1-2018 and GB/T5836.2-2018.
Our product line includes three distinctive forms: straight pipe, expanded pipe, and expanded pipe configurations, compatible with various connection techniques. Additionally, we have engineered pressure drainage pipes ideal for rainwater management, complemented by aesthetically pleasing square rain downspouts, tailored for diverse architectural designs and engineering projects. To further enhance drainage solutions, we have introduced a suite of noise-reducing pipes, including spiral silencers, hollow spiral silencers, and hollow wall silencers, providing a peaceful environment by minimizing drainage sound pollution.

Features
★ Our pipes boast an impressive surface hardness and tensile strength, ensuring a high safety factor in all pipeline applications.
★ With exceptional resistance to aging, these pipelines promise a remarkable lifespan, easily exceeding 50 years of reliable service.
★ Unmatched corrosion resistance to inorganic acids, alkalis, and salts makes these pipelines ideal for industrial sewage discharge and transport.
★ Featuring a low friction coefficient, our pipelines guarantee smooth water flow, minimal clogging, and reduced maintenance efforts.
★ The material exhibits a high oxygen index along with self-extinguishing capabilities, enhancing safety.
★ With a small linear expansion coefficient of 0.07mm/m.ºC, our pipelines experience minimal thermal deformation. They also possess superior frost resistance compared to cast iron drainage pipes.
★ The user-friendly bonding of pipes and fittings allows for simple construction, convenient operation, and high installation efficiency.
★ Ideal for indoor and outdoor drainage in industrial and civil buildings, these pipes support continuous domestic sewage discharge up to 40ºC and instant sewage up to 80ºC. Suitable for non-corrosive industrial wastewater.
Pipe connection
★ Follow these rigorous procedures for effective pipe socket connection:
1. Clean both the pipe socket and fitting socket meticulously before applying adhesive.
2. Accurately measure and mark the socket depth at the pipe port.
3. Apply adhesive evenly—coat the socket first, followed by the pipe fitting socket.
4. Align correctly, insert fully to the marked point, and rotate it by a quarter turn.
5. Remove any excess adhesive from the socket for a clean finish.
6. Allow the bonded pipe to stand until the interface has thoroughly cured.
★ Ensure the safe use of adhesives by adhering to these guidelines:
1. Only operators should use the adhesives and cleaners, and only as needed.
2. Maintain good ventilation and avoid open flames near the bonding site.
3. Construction should not occur below -10ºC, and avoid using fire to dry adhesive points.
4. Personnel must wear gloves; in case of eye contact with adhesive, rinse immediately with water and seek medical help.
Installation instructions
Saw pipe and groove:
The pipe length is determined layer by layer based on actual measurements and fitting dimensions. Use suitable tools like fine-tooth saws, cutters, or pipe cutting machines. Ensure cuts are flat with no section deformation. File the glue socket into a 15°-30° groove with a medium file, ensuring grooves are at least 3mm long and 1/3-1/2 of the wall thickness. Clean all debris post-grooving.
Socket protection:
After socket connection, clean any extruded adhesive using cotton yarn or dry cloth with a detergent like acetone. Allow it to cure according to adhesive performance and climate, extending curing time for winter construction.
