What is a double -walled corrugated pipe? This is a plastic pipe consisting of the outer and inner layer. The outer layer is made in the form of a corrugated plastic pipe made of low -pressure polyethylene, and the inner layer of the pipe is smooth, made of their high pressure polyethylene. Smooth it is made in order to significantly reduce friction between the corrugated layer and the wires located inside, and increase the throughput for wastewater. Using the inner layer, a corrugated pipe can withstand an increased load. Such pipes can be laid in the ground to a depth of 6 meters.
