How Does Multilayer Pipe Ensure Oxygen Barrier And System Longevity
2025-12-01
When designing a durable and efficient plumbing or heating system, preventing oxygen diffusion is a critical challenge. Oxygen entering a closed-loop system, such as underfloor heating or radiators, leads to rapid corrosion of ferrous components, sludge formation, and ultimately, system failure. This is where the advanced engineering of Multilayer Pipe shines. At SUNPLAST, we have perfected this technology to offer a robust solution that guarantees long-term performance and peace of mind for our clients.
The secret to the longevity of our SUNPLAST Multilayer Pipe lies in its intelligent construction. It is not a single material but a composite that leverages the strengths of different polymers and metals.
-
PE-RT Inner Layer: This inner core offers a smooth, corrosion-resistant surface for excellent fluid flow and high-temperature resistance.
-
Aluminum Oxygen Barrier: The center layer is a solid, welded aluminum tube. This layer is completely impermeable, acting as a 100% effective oxygen barrier that protects your entire system from corrosion.
-
EVOH Outer Layer: An additional polymer layer provides further protection and durability.
The combination of these materials results in a pipe that is not only strong but also flexible and easy to install. Below are the key technical parameters of our SUNPLAST Multilayer Pipe:
| Feature | Specification | Benefit |
|---|---|---|
| Layers | 5-Layers (PE-RT, Adhesive, Aluminum, Adhesive, EVOH) | Superior strength and a complete oxygen barrier. |
| Operating Temperature | -10°C to 95°C | Suitable for both hot and cold water applications. |
| Operating Pressure | Up to 10 bar at 95°C | Reliable performance under standard system pressures. |
| Oxygen Diffusion | 0 mg/(l*day) | Prevents corrosion and ensures system longevity. |
Multilayer Pipe FAQ
What makes multilayer pipe better than PEX pipe?
While PEX is a good material, Multilayer Pipe offers superior properties. The embedded aluminum layer in a Multilayer Pipe provides an absolute oxygen barrier, which PEX alone cannot, and it also offers better dimensional stability, meaning it won't expand or deform as much under temperature changes.
Can SUNPLAST multilayer pipe be used for drinking water?
Absolutely. Our SUNPLAST Multilayer Pipe is certified for potable water applications. The inner layer is made from high-grade, non-toxic PE-RT material that ensures the water remains safe and clean, meeting all relevant international health and safety standards.
How do I connect and install SUNPLAST multilayer pipe?
SUNPLAST Multilayer Pipe is designed for quick and easy installation. It can be connected using standard press-fit or compression fittings. Its flexibility allows it to be bent by hand to a certain radius, reducing the number of fittings required and minimizing potential leak points, which saves both time and labor costs.
Protecting your investment and ensuring the efficiency of your heating and plumbing systems is our top priority. The engineered oxygen barrier in our SUNPLAST Multilayer Pipe is your guarantee for a corrosion-free system and unparalleled system longevity. Don't compromise on quality.
