Double-wall corrugated pipe

HDPE double-wall corrugated pipe is a new type of plastic piping manufactured from high-density polyethylene (HDPE) using an extrusion process. Featuring a smooth inner wall and an annularly corrugated outer structure, it combines advantages such as high ring stiffness, light weight, corrosion resistance, and ease of installation. It is a mainstream piping choice for projects including municipal drainage and sewage systems, separate storm and sanitary sewer networks, residential piping networks, and agricultural irrigation.
