PVC-U Drain Pipe Overview: This series of PVC-U drain pipe products stands as a testament to mature technology, enjoying widespread use both domestically and internationally. These pipes boast exceptional features such as unparalleled longevity and corrosion resistance when compared to traditional cast iron pipes. Additionally, during construction, they offer the significant benefits of being lightweight, facilitating easy handling, straightforward installation, and seamless connection. Their versatile application spans across civil building drainage and sewage, chemical drainage and sewage, as well as rainwater drainage and beyond. Notably, PVC-U drainage pipes and fittings strictly adhere to the rigorous standards of GB/T5836.1-2018 and GB/T5836.2-2018, ensuring quality and reliability.
Product Variants and Innovations: Our product range includes three distinct forms: straight pipes, expanded pipes, and expanded pipes, each capable of utilizing various pipe connection techniques. Beyond this, we have innovatively developed pressure drainage pipes specifically designed for efficient rainwater drainage. Our aesthetically pleasing square rain downspouts cater to diverse architectural rainwater drainage designs and engineering needs. Moreover, we have introduced a series of specialized drainage pipes like the spiral silencer, hollow spiral silencer, and hollow wall silencer, all engineered to significantly reduce drainage noise. This comprehensive suite of products ensures optimal performance for all your drainage requirements.

Features
★ Experience the pinnacle of durability! Our pipes boast extraordinary surface hardness and remarkable tensile strength. This meticulous engineering ensures a superior safety factor, safeguarding your pipelines like never before.
★ Unmatched longevity awaits! Our products resist aging gracefully, delivering a reliable service life that extends beyond an impressive 50 years, making them a stalwart choice for long-term projects.
★ Invincible against corrosion! Our pipeline stands as a beacon of resistance to inorganic acids, alkalis, and salts, making it an ideal choice for industrial sewage discharge and transportation solutions.
★ Enhance your efficiency! With a low friction coefficient, our pipelines guarantee smooth water flow, minimizing blockages and reducing maintenance efforts, thereby optimizing your operations.
★ Safety redefined! Our material, with its high oxygen index, boasts exceptional self-extinguishing properties, providing an added layer of safety and peace of mind.
★ Stability you can trust! The pipeline's low linear expansion coefficient of just 0.07mm/m.ºC ensures minimal temperature-induced deformation. Coupled with low thermal conductivity and elastic modulus, our pipes excel in frost resistance, outshining traditional cast iron drainage solutions.
★ Simplified connections for unbeatable efficiency! The straightforward bonding method allows for hassle-free installation, ensuring high efficiency and convenience during the connecting of pipes and fittings.
★ Versatile and robust! Our pipes are ideal for both industrial and civil construction drainage projects, handling continuous domestic sewage up to 40ºC and instant bursts up to 80ºC, provided the wastewater doesn't corrode the pipes.
Pipe connection
★ Achieve optimal results by strictly following these socket connection procedures:
1. Begin by meticulously cleaning both the pipe socket and fitting socket before bonding to ensure a solid connection.
2. Accurately measure the socket depth and mark your pipe port for precise alignment.
3. Apply adhesive thoughtfully; start with the socket, then move to the fitting, ensuring even and appropriate coating.
4. Align your pieces perfectly, insert them to the marked depth in one smooth motion, then give it a quarter turn for secure fitting.
5. Clean any excess adhesive from the socket to ensure a neat finish and reliable bond.
6. Allow the bonded pipe to stand undisturbed until the interface is fully cured for maximum durability.
★ Ensure adhesive safety by adhering to these critical guidelines:
1. Use adhesives and cleaners judiciously, restricting their use to operators only for optimal safety.
2. Maintain a flame-free environment at bonding sites, ensuring excellent ventilation for safe operation.
3. Avoid construction below -10ºC and refrain from using fire to accelerate adhesive setting.
4. Equip your team with gloves; should adhesive contact eyes, rinse immediately with ample water and seek medical care.
Installation instructions
Saw pipe and groove:
Determine saw pipe lengths meticulously, layer by layer, based on precise measurements and fitting dimensions. Opt for fine-tooth saws, cutters, and pipe-cutting machines to achieve flat, deformation-free cuts. Groove the socket area at a 15°-30° angle, ensuring a depth of 1/3 to 1/2 of the pipe wall thickness. Thoroughly clean debris post-grooving for a pristine finish.
Socket protection:
After socket connection, gently clean excess adhesive with cotton yarn or a dry cloth lightly moistened with detergent, like acetone. Allow the joint to cure, adapting curing times to adhesive performance and weather conditions, with extended periods during winter.
