PEX-AL-PEX 3 Layer Composite Piping System

Astral’s MultiPex pipe represents an advanced multilayer (PEX-AL-PEX) composite piping solution that seamlessly amalgamates the strengths of PEX (Cross-Linked Polyethylene) and aluminum while mitigating inherent drawbacks. Comprising a cross-linked polyethylene inner and outer layer with an aluminum middle layer, this innovative pipe offers enhanced strength, rigidity, and durability. The aluminum layer acts as a robust barrier against oxygen diffusion, preventing corrosion and algae growth, making it suitable for continuous operation at temperatures up to 95°C. The preferred and professional choice for joining this pipe is through the efficient crimping method, using specialized tools and fittings, ensuring a secure, leak-proof connection that meets rigorous industry standards. Overall, Astral’s MultiPex pipe, coupled with the crimping process, stands as a reliable, durable, and efficient solution for various applications.
