16mm PE-RT EVOH 3-Layer Pipe for Underfloor Heating Pipe

16mm PE-RT EVOH 3-Layer Pipe for Underfloor Heating

The 16mm PE-RT EVOH 3-Layer Pipe is a high-quality multilayer pipe specially designed for efficient and reliable underfloor heating and cooling systems. It features a durable 3-layer construction with an inner PE-RT (Polyethylene of Raised Temperature) layer, a bonded EVOH (Ethylene Vinyl Alcohol) oxygen barrier, and a protective outer PE-RT layer.

The embedded EVOH oxygen diffusion barrier prevents oxygen ingress into the heating system, significantly reducing the risk of corrosion and extending system life. The pipe's construction ensures flexibility for easy installation, high heat transfer efficiency, and robust performance suited to the demanding conditions of underfloor heating systems.

Key Features

• Diameter: 16 mm
• Wall Thickness: Approximately 2 mm
• Construction: PE-RT inner layer, adhesive bonding layer, EVOH oxygen diffusion barrier, and PE-RT outer protective layer
• Maximum Service Temperature: 70°C (suitable for underfloor heating)
• Maximum Working Pressure: Around 6 bar (typical for underfloor heating at 35-65°C temperatures)
• Bending Radius: Typically 5 x pipe diameter (~80 mm minimum)
• Oxygen Barrier: EVOH layer fully encased to maintain integrity and protect system components
• Flexibility: Highly flexible and lightweight, easier to handle than multilayer PERT-AL-PERT pipes
• Certifications: Compliant with ISO 22391, DIN 4726, and suitable for potable water systems if specified
• Usage: Specifically designed for underfloor heating and cooling systems; not for domestic plumbing applications
• Colours: Usually white outer sheath
• Coil Lengths: Typically available in 80m, 100m, or 160m coils (varies by supplier)

This pipe type ensures long-lasting corrosion protection, energy-efficient heat transfer, and ease of installation for commercial or residential underfloor heating projects. Its excellent flexibility and oxygen barrier make it ideal for maintaining the performance and longevity of modern low-temperature heating systems.

Note: Always verify compatibility with your heating system requirements and consult installation guidelines from the manufacturer or supplier to ensure optimal performance and warranty compliance.
