Our PVC-U drain pipes represent the pinnacle of sophisticated engineering in drainage technology, boasting a rich heritage of global application. These high-performance pipes offer unmatched longevity and corrosion resistance, setting them apart from traditional cast iron alternatives. During construction projects, their lightweight nature not only simplifies handling but also enhances ease of installation and connection. This versatility makes them a preferred choice across various sectors including civil building drainage and sewage systems, chemical drainage, and rainwater management, to name a few. Notably, our PVC-U pipes and fittings conform to rigorous standards as outlined in GB/T5836.1-2018 and GB/T5836.2-2018.
Our product line features three distinctive pipe forms: straight pipe, expanded pipe, and expanded pipe. Each form is compatible with a multitude of pipe connection techniques, offering flexibility for diverse applications. Furthermore, Laoshan Pipe Corporation Limited specializes in pressure drainage pipes crafted specifically for efficient rainwater management, as well as aesthetically pleasing square downspouts tailored for architectural rainwater drainage designs. To address acoustic concerns, we have innovated a range of advanced drainage solutions, including the spiral silencer, hollow spiral silencer, and hollow wall silencer, all engineered to significantly minimize drainage noise and enhance the ambient environment.

Features
★ Experience unmatched durability and safety with our pipe's superior surface hardness and tensile strength ensuring a high pipeline safety factor.
★ Enjoy longevity with our pipe's exceptional aging resistance, offering a service life that can exceed 50 years.
★ Benefit from outstanding corrosion resistance to inorganic acids, alkalis, and salts, making our pipes ideal for industrial sewage discharge and transport.
★ With a low friction coefficient, our pipelines allow smooth water flow, reducing blockages and minimizing maintenance efforts.
★ Feel secure with high oxygen index materials featuring self-extinguishing properties for added safety.
★ The minimal linear expansion coefficient of 0.07mm/m.ºC ensures reduced temperature-induced deformation. The low thermal conductivity and elastic modulus offer superior frost resistance compared to cast iron pipes.
★ Simplify installations with pipe and fitting connections that can be easily bonded, enhancing construction simplicity and boosting installation efficiency.
★ Perfect for industrial and civil building drainage, our pipes handle continuous domestic sewage discharge up to 40ºC and instantaneous sewage discharge up to 80ºC. Compatible with industrial wastewater safe for the pipes.
Pipe connection
★ Ensure perfect pipe socket connections by adhering to these precise steps:
1. Thoroughly clean the pipe socket and fitting socket before bonding to ensure effective adhesion.
2. Measure the socket depth accurately and mark the pipe port for precise alignment.
3. Apply adhesive uniformly; coat the socket first, followed by the socket, ensuring even coverage.
4. Align and insert the pipe into the marked section with a single, smooth motion while rotating it 1/4 turn.
5. Remove any excess adhesive from the socket to maintain a clean and effective connection.
6. Allow the bonded pipe to stand until the interface is fully cured, ensuring robustness.
★ Adhere to these crucial guidelines for the safe use of adhesives:
1. Use adhesives and cleaning agents responsibly, restricting access to trained operators only.
2. Maintain an open flame-free zone at the bonding site, ensuring good ventilation at all times.
3. Avoid construction in temperatures below -10ºC, and never use fire to dry adhesive points.
4. Equip personnel with gloves. In case of adhesive contact with eyes, rinse immediately with plenty of water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine saw pipe length by layer, based on precise measurements and connected pipe fitting dimensions. Use fine tooth saws, cutters, or pipe cutting machines for clean, deformation-free cuts. File the socket area into a 15°-30° groove, ensuring it is at least 3mm long and 1/3-1/2 of the pipe wall thickness. Clear debris post-grooving for optimal adhesion.
Socket protection:
After socket connection, remove excess adhesive with cotton yarn or dry cloth lightly dipped in acetone. Allow curing time based on adhesive performance and climate, extending duration for winter builds.
