The plumbing industry is rapidly moving away from traditional copper and galvanized steel to flexible plastic piping. It is a cost-effective and durable alternative that can deliver great benefits in a wide range of applications. It also has the ability to withstand extreme conditions, and is suitable for residential and commercial water systems.
Cross-linked polyethylene (PEX) is the most popular and widely used type of flexible piping in modern water supply chains. PEX pipes have an excellent resistance to corrosion and other environmental factors, making them a reliable choice for water treatment systems. This article explores the unique features of PEX-AL-PEX pipes, highlighting their benefits and specific applications.
PEX-AL-PEX pipes have an aluminum core sandwiched between two layers of PEX tubing, giving them a higher strength and durability. They are also resistant to a number of chemicals commonly used in gas applications, including disinfectants, oxidizing agents, and pH-adjusting substances. They can also withstand extended exposure to sunlight without compromising their mechanical and chemical properties.
These pipes are easy to install, due to their flexibility. They can easily bend and conform to the layout requirements of the system, reducing the need for additional fittings and connectors and simplifying the installation process. This feature also helps minimize potential leakage points.
Additionally, PEX-AL-PEX has superior lightning strike protection. A recent experimental study comparing common CSST and Pex-AL-Pex pipe found that the former had significantly lower failure rates, even when exposed to a high-current lightning strike. pex al pex pipe
