Our Double Layer PVC Spiral Drain Pipe features a unique double-layer structure, with an outer layer made of robust PVC material and an inner layer that incorporates a spiral design to enhance water flow efficiency and resistance to blockages. The pipe comes in diameters of 75mm, 110mm, and 160mm, with wall thicknesses of 5.0mm, 6.0mm, and 7.0mm, respectively, and a uniform length of 4 meters, catering to diverse project requirements.
The spiral inner layer is the key highlight of this product. This design not only improves drainage efficiency but also effectively prevents debris accumulation, reducing the risk of clogging. Additionally, the double-layer structure ensures greater stability when subjected to external pressure and minimizes deformation risks caused by environmental changes. Whether used for rainwater discharge, wastewater conveyance, or irrigation systems, this drain pipe delivers exceptional performance and reliability.
In the manufacturing process, we strictly control the quality of raw materials and employ advanced production techniques to ensure that each pipe exhibits corrosion resistance and anti-aging properties. Whether installed in damp underground environments or exposed to sunlight outdoors, this drainage pipe can maintain a long service life. Its smooth inner and outer surfaces also facilitate cleaning and maintenance, further enhancing user experience.
