What is Gas Multilayer Pipe?
Our gas multilayer pipe is a five-layer composite pipe that combines the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time. The aluminum core is absolutely diffusion tight, it reliably prevents oxygen/gases from permeating into the pipe. It compensates and reduces snap-back forces and heat expansion with changes in temperature.
- Overlapped welded pipe is co-extruded with one step with perfect adhesive between the inner layer and aluminum, high and stable pressure resistance, of which welding style is ultrasonic.
- Butt welded pipe is molding with several steps that are argon-arc welding style.

Why Use Multilayer Pipes in Gas?
10 Advantages of multilayer pipe for the gas piping system:
- Clean and easy to install, no welding, soldering, thread cutting or bonding
- Easy to bend & Low weight
- Corrosion resistant, thanks to its inner and outer plastic layer
- Excellent long-time rupture strength offers safety in daily use
- Minimal roughness K=0.007mm ensuring less pipe friction and lower pressure losses
- Heat expansion similar to that of metals, enabling larger pipe clip distances
- Excellent long-time rupture strength offers safety in daily use
- Maximum temperature up to 60°C
- Coils and straight lengths in numerous sizes

Tubomart gas pipe can be divided into Pex-Al-Pex pipe and Anti-UV gas pipe. There are five specifications being applied most including 1216, 1418, 1620, 2025, and 2632. We can surely offer any special dimension if you need.
