FIVGAS MULTILAYER PIPE

PEXb - AL - PEXb multilayer pipe

Composition
 
Components
1Inner PE-Xb polyethylene pipe
2Adhesive connection layer
3Aluminium pipe (minimum thickness 0.2 mm)
4Adhesive connection layer
5Outer PE-Xb polyethylene pipe
Info
 
STRUCTURAL FEATURES AND PERFORMANCE
The FIVGAS pipe is manufactured by constructing an aluminium layer inside two layers of polyethylene, followed by a cross-linking process; this allows for combining the advantages of metal (dimensional stability, high resistance to temperature and pressure) to those of plastic (mouldability, chemical inertia).

CONFORMITY TO REGULATIONS
The FIVGAS pipe conforms to the UNI 11344 technical product standard (metal and plastic multi-layer piping systems and couplings for transporting gaseous fuels for internal systems) - UNI/TS 11343 (Gas-fired systems for domestic use - Gas supply systems for domestic use powered by distribution network, supplied by fixed LPG tanks and drums, made with metal and plastic multi-layer piping systems - Design, installation and maintenance) - UNI 11528 (Gas supply systems with heat output exceeding 35 kW - Design, installation and commissioning).
