Why PEX-AL-PEX Gas Systems Are the Smart Choice for Modern Gas Installations

Safe and efficient gas delivery is a top priority for residential, commercial, and industrial projects. Installers and property owners alike need a piping system that combines strength, flexibility, and long-term reliability. PEX-AL-PEX gas systems—multilayer pipes made from cross-linked polyethylene and aluminum—offer exactly that. As more projects demand faster installation and superior safety, this technology is quickly becoming the preferred solution worldwide.

A PEX-AL-PEX pipe is built from three layers:

• Inner PEX layer – cross-linked polyethylene that resists chemical corrosion and high temperatures.
• Middle aluminum layer – a seamless tube that blocks oxygen and gas permeation while adding rigidity.
• Outer PEX layer – additional protection against impact, UV light, and abrasion.

This unique composite creates a pipe that keeps its shape like metal yet remains easy to bend and cut like plastic, combining the best qualities of both materials.

1. Exceptional Safety

   The aluminum core acts as a complete oxygen and gas barrier, minimizing the risk of leaks and pressure loss. TUBOMART PEX-AL-PEX gas pipes are fully certified to ISO 17484, the internationally recognized standard for multilayer gas piping. This certification assures customers that every meter of pipe meets rigorous safety and performance requirements.

2. Long-Term Durability

   These pipes withstand continuous operating temperatures up to 95 °C (203 °F) and the pressures required in gas networks. They resist corrosion, scaling, and chemical attack, ensuring decades of dependable service.

3. Flexible, Time-Saving Installation

   Unlike rigid metal pipes, PEX-AL-PEX tubing can be gently bent by hand or with simple tools. Fewer fittings mean fewer potential leak points and faster installation—an advantage for both new builds and retrofit projects.

4. Cost Efficiency

   Lower labor hours and minimal maintenance translate into reduced total project costs, while the long service life helps protect budgets for years to come.

• Residential kitchens, boilers, and space-heating systems
• Commercial buildings such as restaurants, hotels, and office complexes
• Outdoor or underground gas lines where flexibility and corrosion resistance are critical
• Renovation projects where existing spaces limit the use of rigid piping
