PEX-AL-PEX Pipes

PEX-AL-PEX Pipes

PEX-AL-PEX Pipes are a type of plumbing pipe commonly used in water supply and heating systems. The term PEX-AL-PEX refers to the pipe’s structure: cross-linked polyethylene (PEX) layers bonded to an aluminum (AL) core, sandwiched between two layers of PEX.

These pipes are manufactured by inserting an aluminum layer between two layers of cross-linked polyethylene. This design provides the pipe with additional durability, flexibility, and corrosion resistance. PEX-AL-PEX pipes are widely used in both hot and cold-water installations, as well as underfloor heating systems.

Some advantages of PEX-AL-PEX pipes include:

  • Durability: The aluminum layer adds extra strength and rigidity, helping prevent cracking, leaks, and damage caused by UV exposure, chemicals, and other environmental factors.
  • Flexibility: PEX-AL-PEX pipes are flexible enough to bend and shape around obstacles without the need for additional fittings, reducing leak risks and improving installation efficiency.
  • Corrosion Resistance: The aluminum layer acts as a barrier against corrosion caused by chemicals or minerals in the water supply, making the pipes suitable for drinking water and heating applications.
  • Thermal Performance: PEX-AL-PEX pipes have excellent thermal properties, making them ideal for underfloor heating systems, where they effectively distribute heated water to provide comfortable warmth.
