Choosing the Right Size of PEX Pipe for Your Project

Compared to traditional copper and galvanized steel, PEX (Cross-linked Polyethylene) pipe offers better durability and versatility, making it ideal for both residential and commercial projects. Known for its affordability and ease of installation, it has been rapidly replacing other plumbing materials in new construction projects. PEX pipe can handle both hot and cold water, and is available in a wide range of diameters and lengths. When choosing the right size of PEX for your project, you need to consider how much pressure the system will need to function. PEX tubing comes in both barrier and non-barrier options, depending on your requirements.

Barrier PEX is more expensive than normal PEX pipe, but it has the advantage of an aluminum layer that prevents oxygen penetration. This makes it suitable for heating systems whose components would otherwise corrode if exposed to oxygen. In addition, the aluminum layer helps the tube retain its shape after bending, so it’s less likely to develop leaks at connections.

The aluminum core in barrier PEX also increases its thermal conductivity, allowing for efficient heat transfer and helping to reduce energy costs. Additionally, PEX-AL pipe has excellent flexibility, allowing it to bend and conform to layout requirements. This simplifies the installation process and minimizes potential leak points. PEX-AL pipes are also resistant to a variety of chemicals, including disinfectants, oxidizing agents, and pH-adjusting substances. This resistance to corrosion and other chemical environments ensures their longevity, contributing to overall system reliability.  pex al pex pipe
