PPR-AL-PPR Pipe 50mm x 4Mtrs – PN16

PPR-AL-PPR Composite Pipes (Aluminium Reinforced)

PPR-AL-PPR pipes are high-performance multilayer composite piping systems engineered for reliable hot and cold water distribution. Constructed with an aluminium core sandwiched between inner and outer layers of polypropylene (PPR), these pipes offer superior strength, dimensional stability, and long-term durability compared to conventional plastic piping.

The aluminium layer acts as a reinforcement barrier, significantly reducing thermal expansion and preventing oxygen permeation, making PPR-AL-PPR pipes ideal for demanding plumbing and HVAC applications.

Construction & Design

These pipes are manufactured using a three-layer composite structure:

• Inner Layer: PPR (Polypropylene Random Copolymer) — ensures hygienic and smooth water flow 
• Middle Layer: Aluminium — provides rigidity, pressure resistance, and acts as an oxygen barrier 
• Outer Layer: PPR — protects against environmental and mechanical damage 

This combination results in a pipe system that maintains structural integrity even under high temperature and pressure conditions.

⭐ Key Performance Features

• Low Thermal Expansion
  Up to 5 times lower than standard PPR pipes, reducing bending and sagging 
• High Pressure Resistance
  Available in PN16, PN20, and PN25 classes 
• Oxygen Barrier Protection
  Aluminium layer prevents oxygen ingress, protecting metallic system components 
• Corrosion & Chemical Resistance
  Suitable for aggressive water and industrial environments 
• Smooth Internal Bore
  Minimizes friction loss and prevents scale build-up 
• Long Service Life
  Designed for 50+ years under standard operating conditions 
• Leak-Free Jointing
  Installed using heat fusion welding, ensuring homogeneous joints

Applications

PPR-AL-PPR pipes are suitable for a wide range of applications, including:

• Domestic hot and cold water systems 
• Commercial and residential plumbing installations 
• HVAC and chilled water systems 
• Industrial fluid distribution 
• High-rise building piping systems 

Advantage Over Conventional PPR Pipes

Compared to standard PPR pipes, PPR-AL-PPR offers enhanced mechanical and thermal performance:

• Reduced expansion and improved dimensional stability 
• Higher pressure handling capability 
• Added protection against oxygen diffusion 
• Improved rigidity for long straight runs 

Installation Note

For optimal performance, installation should be carried out using approved fusion welding equipment and in accordance with relevant plumbing standards and best practices.
