Introducing our PVC-U drain pipe collection—a cutting-edge series of drain pipe solutions backed by proven technology and trusted by users globally. These pipes boast an exceptional lifespan and offer remarkable corrosion resistance that outshines traditional cast iron alternatives. The construction advantages include their lightweight nature, which simplifies handling, installation, and connection processes. Widely employed in a variety of applications, including civil building drainage and sewage, chemical drainage, rainwater systems, and more, our PVC-U drainage pipes and fittings strictly adhere to the rigorous standards of GB/T5836.1-2018 and GB/T5836.2-2018.
Our product line offers three distinct forms: straight pipes, expanded pipes, and further expanded pipes, each adaptable to various pipe connection techniques. We've also innovated with pressure drainage pipes tailored for rainwater management, along with aesthetically pleasing square rain downspouts suitable for diverse building designs and engineering projects. Moreover, our specialized drainage pipe series features options such as the spiral silencer, hollow spiral silencer, and hollow wall silencer, all engineered to significantly reduce drainage noise for a quieter environment.

Features
★ Experience the superb surface hardness and impressive tensile strength of our pipeline, ensuring a high safety factor for all your plumbing needs.
★ Revel in the exceptional aging resistance of our product, promising a robust service life of over 50 years, safeguarding your investments for decades.
★ With remarkable corrosion resistance against inorganic acids, alkalis, and salts, our pipeline is ideal for industrial sewage discharge and transport.
★ Enjoy the benefits of a low friction coefficient in our pipeline design, guaranteeing smooth water flow, reduced clogs, and minimized maintenance efforts.
★ Our material boasts a high oxygen index with self-extinguishing capabilities, offering enhanced safety and reliability.
★ Our pipeline's small linear expansion coefficient of 0.07mm/m.ºC ensures minimal deformation from temperature shifts. With lower thermal conductivity and elastic modulus, it excels in frost resistance over cast iron drainage pipes.
★ Benefit from a simple and efficient construction process with our pipe and fittings that can be easily bonded, enhancing installation speed and convenience.
★ Perfect for industrial and residential drainage systems, our product handles continuous domestic sewage up to 40ºC and instant discharges up to 80ºC, while managing non-corrosive industrial wastewater elegantly.
Pipe connection
★ Ensure optimal results by meticulously following these critical pipe socket connection procedures:
1. Thoroughly clean both the pipe socket and fitting socket to prepare for bonding.
2. Precisely measure and mark the socket depth on the pipe port, ensuring accuracy.
3. Apply adhesive meticulously, starting with the socket, then the pipe, ensuring uniform and appropriate coverage.
4. Align properly, insert to the marked depth in one swift motion, and rotate a quarter turn to secure.
5. Carefully remove any excess adhesive from the socket to maintain cleanliness.
6. Allow the bonded pipe to stand undisturbed until the joint fully cures, ensuring a strong bond.
★ Prioritize safety by adhering to these adhesive usage guidelines:
1. Use adhesives and cleaning agents strictly as required, restricting access to trained personnel only.
2. Ensure no open flames are present near bonding sites and maintain excellent ventilation.
3. Avoid construction at temperatures below -10ºC and refrain from using fire to dry adhesive points.
4. Equip construction personnel with gloves; in case of adhesive contact with eyes, rinse with ample water and seek medical attention promptly.
Installation instructions
Saw pipe and groove:
Determine saw pipe lengths based on accurate measurements and connected fitting dimensions. Use fine-tooth saws, cutters, or pipe cutting machines for a clean cut, avoiding section deformation. File socket areas into a 15°-30° groove with medium files, ensuring a groove length over 3mm and a thickness of 1/3-1/2 of the pipe wall. After grooving, clean away debris diligently.
Socket protection:
Post-connection, clean extruded adhesive with cotton or dry cloth using a mild detergent like acetone. Leave the joint static until fully cured, considering adhesive properties and weather conditions. Extend curing time appropriately in colder climates.
