Supply Pure Raw Material Diameter 315 HDPE Double Wall Perforated Corrugated Pipe

**Supply** Pure Raw Material **Diameter 315 HDPE Double-Walled Perforated Corrugated Pipe** **HDPE** perforated corrugated pipe, also known as drainage pipe or blind drainage pipe, is a new type of drainage plastic pipe with a corrugated appearance formed by adding other additives to polyethylene (PE). It is divided into single and double-walled perforated corrugated pipes, characterized by light weight, strong pressure resistance, excellent bending performance, and ease of construction. **18603793535 Jiangtai Technology HDPE corrugated pipe manufacturer** Due to the elongated shape of the perforations located in the valleys of the pipe, this product effectively overcomes the drawback of flat round hole products, which are easily blocked and can affect drainage efficiency. It is suitable for different drainage requirements. The size of the perforations can range from 10mm×1mm to 30mm×3mm, and they can be evenly distributed within a range of 360 degrees, 270 degrees, 180 degrees, and 90 degrees. Common specifications: Φ50mm single-walled perforated corrugated pipe is used for circumferential drainage in tunnels; Φ100mm double-walled perforated corrugated pipe is used for longitudinal and transverse drainage in tunnels; Φ400mm double-walled perforated corrugated pipe is used for central drainage in tunnels and for longitudinal and transverse drainage in subgrade and pavement projects.
