Multilayer pipe PEX-Al-PEX - GAS PROTEK - corrugated multypexalfa Plastica Alfa

Multilayer pipe PEX-Al-PEX – GAS PROTEK – corrugated

SKU: CGTMG Categories: , ,

The multilayer PEX-Al-PEX GAS PROTEK pipe belonging to the Multypexalfa gas line is a PEXb-Al-Pexb pipe produced by Plastica Alfa for the transport of gaseous fuels (natural gas and LPG) in domestic installations. The pipe consists of five layers: the two PExb layers (inner and outer) are bonded to the aluminium intermediate layer by two stabilised polymer bonding layers. The aluminium layer provides an oxygen barrier, reduces linear thermal expansion effects and gives the tube dimensional stability and flexural strength.

The corrugated sheath is made of self-extinguishing, UV-resistant yellow PPB and provides strong protection for the inner pipe in the case of installations in perimeter walls in both civil and industrial applications.
