The PVC-U drain pipe is an exceptional series of drainage solutions with tried-and-true technology that has seen extensive use both domestically and internationally. These pipes offer a remarkable lifespan and corrosion resistance, unmatched by traditional cast iron alternatives. They are lightweight, facilitating easy handling, installation, and connection, making them ideal for a broad spectrum of applications. These include civil construction drainage and sewage systems, chemical and industrial effluent management, and effective rainwater harvesting systems. All PVC-U drainage pipes and fittings adhere strictly to the standards set by GB/T5836.1-2018 and GB/T5836.2-2018.
Our product range includes versatile forms such as straight pipes, expanded pipes, and variations therein, accommodating a wide array of connection methods. Beyond the standard offerings, we have innovated pressure drainage pipes tailored for efficient rainwater management and aesthetically pleasing square rain downspouts, enhancing rainwater system design for diverse architectural projects. Furthermore, we provide specialized drainage pipe solutions like spiral silencers, hollow spiral silencers, and hollow wall silencers, expertly designed to minimize drainage noise, enhancing the tranquility of any environment.

Features
★ Unmatched surface hardness and tensile strength make our pipeline outstanding, ensuring a superior safety factor and unmatched reliability.
★ With remarkable aging resistance, our pipes promise an impressive service life, exceeding an extraordinary 50 years, offering peace of mind for decades.
★ The pipeline is fortified with exceptional corrosion resistance against inorganic acids, alkalis, and salts, making it an ideal choice for industrial sewage discharge and transport.
★ Experience smooth water flow due to the pipeline's low friction coefficient, minimizing blockages and reducing maintenance workloads significantly.
★ The material's high oxygen index and self-extinguishing capabilities add an extra layer of safety, making it an intelligent choice for secure implementations.
★ With a minimal linear expansion coefficient of 0.07mm/m.ºC, temperature-induced deformation is negligible. Its thermal conductivity and elastic modulus are low, offering superior frost resistance compared to cast iron drainage pipes.
★ The pipe and fittings connect seamlessly with bonding, simplifying construction, easing operations, and significantly enhancing installation efficiency.
★ Perfect for industrial and civilian buildings, our pipelines manage indoor and outdoor drainage projects effectively, handling domestic sewage at temperatures up to 40ºC, with instant discharges up to 80ºC. They also efficiently convey industrial wastewater that won't corrode the pipe.
Pipe connection
★ Ensure secure pipe socket connections by strictly following these detailed procedures:
1. Begin by meticulously cleaning both the pipe socket and the fitting socket before applying bonding.
2. Measure the socket depth with precision and clearly mark the pipe port for accuracy.
3. Apply the adhesive with care: first coat the socket, then the fitting socket, ensuring uniform and appropriate coverage.
4. Align precisely, insert to the marked part in one motion, and execute a 1/4 turn for secure fitting.
5. Clean the remaining adhesive from the socket thoroughly to ensure a clean finish.
6. Allow the bonded pipe to stand undisturbed until the interface fully cures, ensuring a strong bond.
★ Adhere to these safety guidelines for the proper use of adhesives:
1. Use adhesives and cleaning agents judiciously, restricting access to trained operators only.
2. Maintain a flame-free environment at bonding sites and ensure optimal ventilation at all times.
3. Avoid construction in temperatures below -10ºC and refrain from using fire to heat adhesive points.
4. Equip construction personnel with protective gloves. In case of eye contact with adhesive, rinse immediately with ample water and seek medical attention promptly.
Installation instructions
Saw pipe and groove:
Determine the length of the saw pipe meticulously, layer by layer, based on precise measurements and the dimensions of each connected fitting. Utilize tools such as fine-tooth saws, cutters, and pipe cutting machines for precision. Ensure a flat fracture without deformation. File the socket area into a 15°-30° groove, with a length not less than 3mm and a depth of 1/3-1/2 the pipe wall thickness. After grooving, clear away all debris for a clean finish.
Socket protection:
After socket connection, cleanse the extruded adhesive using cotton yarn or a dry cloth moistened with a gentle detergent like acetone. Allow the socket to stand still, curing according to adhesive performance and climatic conditions. Extend curing time appropriately for winter construction.
