To introduce you to the PEX pipes family


PEX, or cross-linked polyethylene, revolutionizes modern plumbing with advanced materials and manufacturing. This article explores PEX pipes definitions and types (PEX-A, PEX-B, PEX-al-PEX) for a comprehensive understanding.

What is PEX Pipes

PEX pipe, an advanced material made of crosslinked polyethylene, offers numerous advantages over traditional metal pipes. Its lightweight and flexible nature simplifies installation and maintenance processes. High temperature and corrosion resistance render PEX pipes suitable for various applications including water supply and heating systems. Manufacturing methods like peroxide, wet curing, and irradiation treatment create PEX-A, PEX-B, and PEX-C types, meeting diverse needs.

Characteristics of each PEX pipes family member

When it comes to the choice of pipes, PEX pipe provide us with a versatile and more reliable solution. But did you know that there are different kinds of PEX pipes available to consumers? Let’s explore the three main types – PEX-A, PEX-B, and PEX-AL-PEX – and compare their unique properties.

Manufacturers produce PEX-A pipe using the peroxide method, creating a highly cross-linked structure. This increased flexibility enables PEX-A pipes to bend around corners easily, eliminating the requirement for additional compression joints.

They have excellent frost resistance, making them ideal for use in cold weather. Thanks to its thermal and elastic memory, the PEX-A pipe continually seeks to return to its original shape, demonstrating exceptional durability.

Polystyro-b piping is manufactured by the silane process and offers excellent durability and resistance to extreme temperatures. Although slightly less flexible compared to the PEX-A pipe, it still provides excellent performance. Praised for its ability to withstand high temperatures and maintain structural integrity, PEX-B pipes are a reliable choice for a variety of pipeline applications.

PEX-AL-PEX piping, also known as multi-layer piping, is the ultimate combination of metal and plastic. Its unique construction consists of an aluminum core sandwiched between two layers of PEX material, providing superior strength, rigidity and flexibility.

PEX-AL-PEX pipes are extremely resistant to corrosion and show excellent performance in water piping and underfloor heating systems. They bend effortlessly around corners, demonstrating excellent flexibility and adaptability in piping systems.

PEX pipes offer several advantages over traditional pipe materials.

Its flexibility allows it to be easily installed in confined Spaces without the need for additional accessories.

PEX pipes withstand high temperatures for hot and cold water lines, with corrosion resistance for long-lasting performance and minimal maintenance.

The main advantage of one of the PEX tubes is its excellent freeze resistance, which allows it to expand and contract at freezing temperatures without breaking, making it ideal for cold climates.

Compared to copper or PVC pipe, PEX offers significant material and installation cost savings without sacrificing quality or performance.

PEX tubing has a long life, providing years of durability and reliability. Its corrosion resistance, frost resistance and flexibility contribute to extended service life.

Due to its versatility and adaptability, PEX tubing can be used in a variety of applications, including water supply piping, underfloor heating and snow melting systems.


In the field of pipes, the new features of PEX pipes and various types of options provide users with more flexible, economical and sustainable solutions. From frost resistance to durability, different types of PEX pipes show their unique advantages. Overall, PEX pipelines perform well in solving the problems of traditional pipeline systems, improving efficiency and reducing costs. As technology advances, PEX pipelines are expected to dominate, offering reliable liquid transport solutions for various environments.
