Five-Layer Composite Construction
The PERT Al PERT pipe uses five layers: PERT, adhesive, aluminum, adhesive, and PERT. Each layer performs a distinct function.
Durable Inner and Outer PERT Layers
Manufacturers use PERT for inner and outer layers. These layers offer flexibility, corrosion resistance, and long-term stability.
Adhesive Layers Enhance Bonding
Two adhesive layers bond the aluminum and PERT. They prevent delamination under heat and pressure changes.
Seam-Welded Aluminum Core
The aluminum layer includes a laser or overlap weld. This weld ensures pipe strength and shape memory over time.
Anti-Oxygen Barrier Layer
The aluminum blocks oxygen from entering the system. This feature protects metal components inside heating or plumbing networks.
Low Thermal Expansion
The aluminum core controls thermal expansion. Installers experience fewer distortions compared to full-plastic alternatives.
Smooth Inner Flow Channel
The inner surface remains smooth and clean. Fluids move efficiently and avoid sediment or calcium buildup.
Working Pressure and Temperature
Manufacturers rate the pipe for 10-bar pressure. It handles up to 95°C in continuous heating systems.
Available Sizes and Thickness
Suppliers offer sizes from 16mm to 32mm. Wall thickness typically ranges from 2mm to 3mm.
Markings and Identification Lines
Pipes include printed specifications and colored stripes. These help installers quickly identify application and pipe orientation.
