STAR pipes are made of PE 100 and PE 100 RC and are used in industry, supply and disposal.
What is the difference between single and multi-layer pipes?
What are single-layer pipes?
Single-layer pipes are solid wall pipes whose wall consists of only one material and color. Optionally these tubes are available with blue, red, orange or brown stripes.
What are multi-layer pipes?
By using the co-extrusion process, the outer and/or inner layer are usually given a coloring, while maintaining the standard dimension. The outer diameter as well as the wall thickness of the pipe remain unchanged.
