CSA B137.5 Multilayer Plumbing Pipe BS En 12201-316-32mm Insulated Multilayer Pipe

WRAS APPROVED PEX AL PEX PIPE

APEX brand PEX-AL-PEX pipe, a composite pipe with layers of PEX and aluminum, offers several advantages over traditional piping materials like copper and PVC. These include durability, flexibility, corrosion resistance, and suitability for both hot and cold water plumbing and heating systems. The aluminum layer provides added strength and helps the pipe retain its shape, while the PEX layers offer flexibility and resistance to corrosion and freezing. 

16mm, 20mm, 25mm, 32mm Multilayer Pex-Al-Pex Pipe Advantages

Durability:
The aluminum layer adds strength and rigidity, making PEX-AL-PEX pipes less susceptible to damage from external forces or bending.  
Corrosion Resistance:
PEX-AL-PEX pipes are highly resistant to corrosion and tuberculation, making them suitable for use with various water qualities.  
Flexibility:
PEX-AL-PEX pipes are flexible, making them easier to install in tight spaces and around obstacles.  
Temperature Resistance:
They can handle a wide range of temperatures, making them suitable for both hot and cold water applications.  
Oxygen Barrier:
The aluminum layer acts as an oxygen barrier, preventing oxygen from permeating the pipe and potentially causing corrosion in heating systems.  
Reduced Fittings:
The flexibility of PEX-AL-PEX allows for longer pipe runs with fewer connections, reducing the risk of leaks.  
Freeze Resistance:
PEX-AL-PEX pipes are less likely to burst from freezing compared to rigid pipes.  
Easy Installation:
They are lightweight and relatively easy to install, which can save time and labor costs.  
Longevity:
Due to their durability and resistance to corrosion, PEX-AL-PEX pipes are known for their long lifespan.
