The PVC Flat Offset Pipe is a high-performance drainage solution designed for modern construction and municipal projects, with a unique flat profile that excels in space-constrained environments. Manufactured from premium-grade PVC, it offers outstanding resistance to corrosion, aging, and deformation, maintaining reliable performance even under prolonged exposure to moisture or chemical contact. The smooth interior surface significantly reduces flow resistance, enhancing drainage efficiency while minimizing the risk of blockages.
Compared with conventional round pipes, the flat offset design effectively saves vertical space, allowing seamless parallel installation alongside other utility lines and enabling more efficient spatial planning. Its geometry provides exceptional flexibility for routing through walls, beams, or ceiling cavities, making it ideal for concealed installations in residential, commercial, and underground applications. Available in D60×35 mm and D110×60 mm sizes, with lengths of 2 m and 4 m, it accommodates diverse project requirements.
Installation is quick and straightforward, requiring only standard PVC solvent cement to create strong, leak-proof joints—no special tools needed. Its lightweight nature ensures easy handling, reduces labor intensity, shortens construction timelines, and minimizes structural load. Non-toxic and odorless, the pipe meets national environmental and safety standards, making it suitable for residential wastewater systems. The manufacturing process is energy-efficient, and the material is fully recyclable, aligning with sustainable building practices.
