    摘要: The present invention relates to pipes for the transmission and/or distribution of combustible gases, and liquefied gases, comprising a polyethylene layer and a polyamide inside and/or outside layer. These pipes may advantageously be connected together by adhesively bonded sleeves and thus form medium-pressure and low-pressure gas distribution and transmission networks or else they may be installed inside already existing metal pipes. These pipes may be manufactured by coextrusion.
