Perforated HDPE underground drain pipe is made of high density polyethylene (HDPE), and it has excellent chemical stability, aging resistance and environmental stress cracking. The HDPE double-wall corrugated pipes belong to one type of flexible pipe. It is extruded to fit the new type of pipe for the outdoor drainage and municipal discharge. HDPE double wall corrugated pipe has the advantages of light weight, small displacement resistance, high compressive strength, corrosion resistance and convenient construction. Underground drainage pipe is an ideal material to replace cast iron pipe and cement pipe.

Perforated HDPE Corrugated Drain Pipe With Filter Sock  is used in land drainage subsoil (underground) applications ,By its name perforated pipe has perforations along the pipe. This allows water to enter the pipe through these perforated holes. They are thus suitable for subsoil drainage systems, ideally suited to applications such as Field Drain or French Drains.
