FILLED PIPE

[ KS M 3500-4 ]

High-Density Triple-Layer Filled Pipe

Use

Sewage treatment, agricultural water, dirty water/ precipitation, drainage uses

Internal structure

Features

The high-density three-layer filled pipe consists of three layers: an internal layer where the flow path is formed; an external layer directly in contact with soil; and the intermediate layer between internal and external layers, which gives durability to the pipe. Three extruders are used simultaneously for the extrusion molding of the three-layer structure in the manufacturing process. The internal surface of the pipe is filled with compounds of polyethylene and filler, which enables high resistance to external pressure. The weight of the pipe is higher than that of water, this means that there'll be no bouyancy issues.
