PVC-U drain pipe represents a sophisticated collection of drainage solutions, boasting a wealth of technological refinement. It has garnered extensive utilization both domestically and internationally. These exceptional products offer a lifespan and corrosion resistance vastly superior to that of traditional cast iron pipes. During construction, they stand out due to their lightweight nature, which facilitates effortless handling, installation, and seamless connectivity. Widely embraced in the realms of civil building drainage, sewage systems, chemical drainage, sewage management, and rainwater drainage, these pipes and fittings are indispensable. They comply with the stringent standards of GB/T5836.1-2018 and GB/T5836.2-2018, ensuring reliability and quality.
This remarkable product line comprises three distinct forms: straight pipes, expanded pipes, and further expanded pipes, offering versatility in pipe connection methodologies. Furthermore, our company has pioneered the development of pressure drainage pipes specifically for efficient rainwater management, along with aesthetically appealing square rain downspouts tailored for diverse architectural designs. To combat drainage noise effectively, an innovative series of pipes has been created, including spiral silencers, hollow spiral silencers, and hollow wall silencers, all designed to significantly reduce noise during drainage operations.

Features
★ Experience superior durability with our pipes, boasting exceptional surface hardness and tensile strength, ensuring a high safety factor for your pipeline systems.
★ Enjoy long-lasting reliability thanks to excellent aging resistance, offering a normal service life that extends beyond five decades.
★ Benefit from outstanding corrosion resistance against inorganic acids, alkalis, and salts, making these pipes ideal for industrial sewage discharge and transport.
★ Appreciate the low friction coefficient, ensuring a smooth water flow that minimizes blockages and reduces maintenance efforts.
★ The material's high oxygen index and self-extinguishing properties enhance safety and performance.
★ With a minimal linear expansion coefficient of 0.07mm/m.ºC, temperature-induced deformation is negligible. Its low thermal conductivity and elastic modulus improve frost resistance over cast iron pipes.
★ Simplify construction with easy bonding connections for pipes and fittings, boosting installation efficiency with straightforward operations.
★ Suitable for industrial and residential drainage projects, managing continuous domestic sewage at temperatures up to 40ºC, and instant discharge up to 80ºC. Compatible with non-corrosive industrial wastewater.
Pipe connection
★ Ensure quality pipe socket connections by adhering to the following meticulous procedures:
1. Thoroughly clean the pipe socket and fitting socket prior to bonding for optimal adhesion.
2. Accurately measure and mark the depth of the socket to ensure precise alignment.
3. Apply adhesive evenly; coat the fitting socket first, followed by the pipe socket, for a uniform bond.
4. Align and insert the pipe into the marked section, completing a quarter-turn to secure the connection.
5. Remove any excess adhesive from the socket to maintain a clean and neat joint.
6. Position the bonded pipe upright until the joint is fully cured, ensuring a robust connection.
★ Safely manage adhesive usage by following these essential guidelines:
1. Limit adhesive and cleaning agent use to trained operators only, preventing unauthorized handling.
2. Maintain a flame-free environment at bonding sites and ensure good ventilation for safety.
3. Avoid construction in temperatures below -10ºC and refrain from using open flames to dry adhesive points.
4. Equip construction personnel with gloves, and in case of adhesive contact with eyes, rinse immediately with water and seek medical attention.
Installation instructions
Saw pipe and groove:
Determine pipe lengths layer by layer based on precise measurements and connection dimensions. Opt for tools like fine-tooth saws, cutters, or pipe cutting machines for clean cuts. Ensure the cut is level and free from section deformation. File the socket section into a 15°-30° groove using a medium board file, with groove length not less than 3mm and thickness 1/3-1/2 of the pipe wall. Clear debris post-grooving.
Socket protection:
Post-connection, clean excess adhesive with cotton yarn or dry cloth moistened with a mild detergent like acetone. Allow the joint to cure statically as per adhesive properties and climate conditions, extending curing time in winter.
