A critical aspect of their reliability lies in the permanent joining technique. While various methods exist, heat fusion is the gold standard for creating leak-proof, monolithic connections. The two primary heat fusion techniques are Butt Fusion and Socket Fusion, each with distinct advantages. Overlap Welding: The Standard for Simplicity Overlap Welding is the most common and straightforward method for joining PEX-Al-PEX pipes. This process involves using a pre-manufactured fitting, such as an elbow or coupler, whose internal diameter is slightly smaller than the pipe's outer diameter. The procedure requires a specialized overlap welding tool equipped with heating plates of specific diameters. The process begins by cleaning the pipe end and the fitting's interior. The fusion machine heats both components simultaneously. Once the polyethylene surfaces reach a precise melting temperature, the pipe is swiftly inserted into the fitting socket. A brief holding period is crucial, allowing the molten PEX layers from both parts to intermix and cool under pressure. The result is a homogeneous joint that is as strong as the pipe itself. The key advantage of socket fusion is its speed and simplicity, making it ideal for standard residential and commercial gas line installations where prefabricated fittings are readily available. Butt Welding: Strength for Direct Connections Butt Welding is employed when a direct, fitting-less connection between two pipe ends is required. This method is particularly useful for creating long, continuous runs or repairing a section of pipe. The process requires a butt fusion machine that aligns the two pipe ends perfectly in a clamp. The steps involve facing the pipe ends to ensure they are perfectly square and clean. A heating plate, with a non-stick surface, is then inserted between the clamped ends. The pipes are pushed against the plate until the PEX layers melt. The heater is quickly removed, and the two molten ends are pressed together with a controlled force. This pressure forces the polyethylene molecules to intertwine across the interface, forming a seamless, continuous joint upon cooling. The primary benefit of butt welding is the elimination of a fitting, which reduces potential leak points and minimizes flow resistance. However, it demands more skill, a more robust machine, and strict control over heating and pressing parameters to avoid defects like cold fusion. Conclusion The choice between butt and overlap welding for PEX-Al-PEX gas pipes depends on the application's specific requirements. Overlap welding, with its use of standard fittings, offers unmatched ease and efficiency for most branching installations. In contrast, butt welding provides superior hydraulic efficiency and is indispensable for long, straight pipelines. In both cases, operator training and strict adherence to the manufacturer's procedures—including correct temperature, pressure, and heating time—are non-negotiable for ensuring the long-term safety and integrity of the gas system.

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.   What Is a PEX-AL-PEX Gas System?   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.   Key Advantages   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.   Common Applications • 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   TUBOMART PEX-AL-PEX Gas Solutions   TUBOMART offers a comprehensive range of PEX-AL-PEX gas pipes and fittings designed to meet international safety certifications such as ISO 17484 and CSA.
