The PE-RT-ALU-PE metal composite pipe consists of two layers of polyethylene (PERT), two adhesive layers, and one aluminum layer. PERT gives the pipe high resistance to high temperatures without the need for an additional cross-linking process. The pipe is easy to handle, flexible, pliable, lightweight, and durable. It ensures a complete barrier against oxygen and water vapor and offers optimal protection against odor transmission and corrosion. The smooth inner surface of the pipe is resistant to common substances found in water.
