Our PVC-U drain pipe series represents a pinnacle of engineering, featuring a sophisticated technology that has been globally embraced for its superior attributes. Unmatched by traditional cast iron pipes, these products boast a remarkable lifespan and extraordinary resistance to corrosion. During construction, these pipes stand out for their lightweight nature, ease of handling, and seamless installation and connection, making them ideal for a myriad of applications. From civil building drainage and sewage management to chemical waste disposal and rainwater handling, our PVC-U drainage pipes excel. They are crafted to meet the stringent standards of GB/T5836.1-2018 and GB/T5836.2-2018, ensuring reliability and performance.
Our innovative product line offers three distinct forms: straight pipes, expanded pipes, and expanded pipes with varying connection methods. We have also pioneered pressure drainage pipes designed specifically for rainwater management, alongside elegant square rain downspouts tailored for diverse architectural designs. Moreover, our advanced series includes the spiral silencer, hollow spiral silencer, and hollow wall silencer, all engineered to significantly diminish drainage noise, enhancing the tranquility of your environment.

Features
★ Witness the unparalleled surface hardness and tensile strength of our pipes, ensuring an exceptional safety factor that stands the test of time.
★ Bask in the assurance of superior aging resistance, with a remarkable service life extending beyond 50 glorious years.
★ Our pipes shine with extraordinary corrosion resistance against inorganic acids, alkalis, and salts, making them ideal for industrial sewage discharge and transport.
★ Featuring a low friction coefficient, our pipelines promise smooth water flow, minimal blockages, and a significant reduction in maintenance efforts.
★ The material boasts a high oxygen index with self-extinguishing properties, setting a benchmark in safety.
★ Experience minimal thermal expansion with a linear expansion coefficient of just 0.07mm/m.ºC, ensuring negligible temperature-induced deformation. Enjoy better frost resistance compared to traditional cast iron pipes, thanks to lower thermal conductivity and elastic modulus.
★ Simplified connection process: pipes and fittings can be effortlessly bonded for efficient installation, enhancing ease of construction and boosting productivity.
★ Perfectly suited for both industrial and residential building drainage systems. Ideal for continuous discharge of domestic sewage below 40ºC and instantaneous discharges up to 80ºC, our pipes are also compatible with industrial wastewater that does not corrode the piping.
Pipe Connection
★ Ensure a meticulous pipe socket connection by strictly adhering to these procedures:
1. Thoroughly clean both the pipe socket and the corresponding fitting socket before bonding to ensure a perfect fit.
2. Accurately measure the depth of the socket and make a precise mark on the pipe port.
3. Apply the adhesive uniformly, starting with the socket and then the pipe socket, ensuring an even coat throughout.
4. Carefully align and insert into the marked section in one motion, followed by a 1/4 rotational twist for optimal bonding.
5. Neatly wipe away any excess adhesive from the socket to maintain a clean finish.
6. Allow the bonded pipe to stand undisturbed until the interface fully cures, ensuring a robust connection.
★ Adhere to these crucial safety guidelines for adhesive use:
1. Use adhesives and cleaning agents judiciously. Non-operators must refrain from usage to maintain safety.
2. Ensure a no open flame zone at bonding points, coupled with excellent ventilation for a safe working environment.
3. Avoid construction below -10ºC and strictly prohibit fire exposure at adhesive points to prevent hazards.
4. Equip construction personnel with protective gloves. In case of adhesive contact with eyes, flush with plenty of water immediately and seek medical attention.
Installation Instructions
Saw Pipe and Groove:
Determine the saw pipe length meticulously, layer by layer, based on measured dimensions and connected fittings. Opt for fine tooth saws, cutters, or pipe cutting machines. Ensure a flat fracture with no sectional deformation. File the socket portion into a 15°-30° groove, ensuring the groove length is no less than 3mm and thickness is within 1/3-1/2 of the pipe wall thickness. Remove debris post-grooving for a clean finish.
Socket Protection:
Post-socket connection, cleanse the extruded adhesive using cotton yarn or a dry cloth moistened with a mild detergent like acetone. Allow the interface to cure statically, adjusting for adhesive performance and climate conditions. In winter, extend the curing time appropriately for optimal results.
