The tubes used to transport gas are made of PEBD (low density Polyethylene) which is a homopolymeric or copolymeric resin of polyethylene added to anti-oxidative, pigments and ultra-violet stabilizers, etc...

PEBD tubes advantages :
  • Easy transport and installation thanks to their lightness and flexibility
  • Easy soldering through end-to-end electrofusion, allowing a totally-soldered system
  • Resistance to internal, external and microbiological corrosion
  • High chemical resistance
  • Long life time with minimal final cost
