The PVC-U Drain Pipe Series is a testament to advanced, time-tested technology and has garnered widespread acclaim both domestically and internationally. These pipes boast an incredible lifespan and resistance to corrosion, far surpassing that of traditional cast iron pipes. This innovative range is crafted for ultimate convenience with lightweight properties that simplify handling, installation, and connectivity. Perfectly suited for civil infrastructure, chemical applications, and rainwater management, these pipes excel in diverse drainage scenarios. Complying with the rigorous standards of GB/T5836.1-2018 and GB/T5836.2-2018, our PVC-U drainage pipes and fittings promise unparalleled reliability and performance.
Our product comes in three distinct configurations: straight pipe, expanded pipe, and expanded pipe with a plethora of connection options. Beyond this versatility, Laoshan Pipe Corporation Limited has engineered specialized pressure drainage pipes specifically tailored for efficient rainwater management, as well as aesthetically pleasing square rain downspouts to complement architectural designs. Further enhancing our drainage solutions, we offer a sophisticated array of noise-reducing pipes, including spiral silencers, hollow spiral silencers, and hollow wall silencers, each engineered to minimize acoustic disturbances during drainage.

Features
★ The Clear Flexible PVC PIPE boasts outstanding surface hardness and tensile strength, delivering a high safety factor for peace of mind in every application.
★ Enjoy remarkable aging resistance with this pipe, ensuring a reliable service life exceeding 50 years, providing long-term value and dependability.
★ Exceptionally resistant to corrosion from inorganic acids, alkalis, and salts, this pipe is perfectly suited for industrial sewage discharge and transportation, guaranteeing effective performance.
★ With a small friction coefficient, water flows smoothly through the pipeline, reducing the risk of blockages and minimizing maintenance demands.
★ The material's high oxygen index offers self-extinguishing properties, enhancing safety and peace of mind.
★ The pipeline's small linear expansion coefficient of 0.07mm/m.ºC means minimal deformation due to temperature changes. Its low thermal conductivity and elastic modulus also provide superior frost resistance compared to cast iron drainage pipes.
★ Bonding the pipe and fittings is straightforward, with a simple construction method and convenient operation, leading to high installation efficiency.
★ Perfectly designed for industrial and civil building drainage projects, the pipe accommodates indoor and outdoor applications, handling continuous domestic sewage at temperatures up to 40ºC and instant discharges up to 80ºC. It is ideal for industrial wastewater that does not corrode the pipe.
Pipe connection
★ Ensure precise pipe socket connections by following these meticulous procedures:
1. Before bonding, meticulously wipe both the pipe socket and fitting socket clean.
2. Accurately measure the socket depth and mark the pipe port for precision.
3. Apply adhesive with care: paint the socket first, followed by the fitting socket evenly and appropriately.
4. Align the direction, insert it to the marked part quickly, and execute a smooth 1/4 turn.
5. Wipe away any excess adhesive from the socket meticulously.
6. Allow the bonded pipe to stand until the interface is fully cured for optimal strength.
★ The safe use of adhesives necessitates adherence to the following guidelines:
1. Use adhesives and cleaning agents only as required, preventing unauthorized usage by non-operators.
2. Maintain a flame-free environment at bonding points, ensuring excellent ventilation.
3. Avoid construction in temperatures below -10ºC, and refrain from using fire to bake adhesive points.
4. Construction personnel should wear gloves. If adhesive contacts the eyes, flush immediately with water and seek medical attention promptly.
Installation instructions
Saw pipe and groove:
Determine the saw pipe length precisely, layer by layer, according to measured measurements and connected pipe fitting dimensions. Opt for fine tooth saws, cutters, and pipe cutting machines for clean cuts. Ensure the fracture is flat with no section deformation. File the socket part into a 15°-30° groove with a medium board file. Aim for a groove length of no less than 3mm, with a thickness of 1/3-1/2 of the pipe wall. After completing the groove, promptly clear away debris.
Socket protection:
After socket connection, meticulously clean the extruded adhesive with cotton yarn or a dry cloth soaked in a mild detergent like acetone. Allow the joint to remain static until the interface is cured based on adhesive performance and weather conditions. Extend curing time appropriately during winter construction.
