Plastic pipe systems made of Polypropylen (PE) for securely welded piping systems
As a pipe manufacturer, we produce pipes for industrial plant construction, as well as municipal drainage networks and supply networks. We use the proven materials PE100 and PE100-RC for our pipe production.
Where is the difference between single-layer and multi-layer pipes?
What is a single-layer pipe?
Single-layer pipes are solid-wall pipes where the wall consists of only one material and one color. These pipes are optionally available with blue, red, orange or with brown stripes.
What is a multilayer pipe?
Using a coextrusion process, the pipe is given an outer and/or inner layer, usually in a contrasting color, within the standard dimensions. The outer diameter and wall thickness of the pipe remain unchanged.
