Embodiment Construction
[0020] As shown in the drawings: a gas delivery pipeline, including an inner layer 1, an intermediate layer 2 and an outer layer 3, the inner layer 1 is a waterproof and anti-oxidation pipe blank metal layer, the middle layer 2 is a PET insulation layer, and the insulation layer includes an inner layer PET layer, insulation layer and outer PET layer, the outer layer 3 is an alloy layer, and the thickness of the gas pipeline 6 is 0.5-4cm. Preferably, the thickness of the gas pipeline 6 is 1-3 cm; more preferably, the thickness of the gas pipeline 6 is 0.6 / 1.5 / 2 / 2.2 cm; it is convenient to improve the structural strength and pressure bearing capacity of the gas pipeline 6 .
[0021] In the embodiment, the two ends of the gas delivery pipeline are connected by the annular connecting piece 4 and fixed by welding. It is convenient to improve the structural strength of the gas pipeline, and at the same time prevent the outer layer 3 of the gas pipeline 6 from loosening or falling of...
