The invention discloses a natural gas conveying pipeline which comprises an inner pipe, an outer pipe, a heat preservation layer arranged between the inner pipe and the outer pipe and connecting pieces arranged at the two ends of the inner pipe and the two ends of the outer pipe, the outer pipe and the inner pipe are concentrically arranged, and the distance between the inner pipe and the outer pipe is 3-5 cm. And the thickness of the inner pipe is the same as that of the outer pipe. Natural gas is conveyed through the inner pipe, the middle heat preservation layer plays a heat preservation role so as to guarantee the stability of natural gas conveying in the inner pipe, and the problem that the air pressure fluctuation in the inner pipe is large due to large temperature difference is solved. Meanwhile, the outer pipe can protect the inner pipe, and when the inner pipe is subjected to external force, due to protection of the outer pipe, deformation of the inner pipe is avoided, and leakage of the inner pipe is avoided.

    本发明公开了一种天然气输送管道,包括内管、外管、设置在所述内管和所述外管之间的保温层,以及设置在所述内管和所述外管两端的连接件,所述外管和所述内管呈同心设置,且所述内管和所述外管之间的间距为3‑5cm,所述内管的厚度与所述外管的厚度相同。天然气通过内管进行输送,中间的保温层起到保温作用,以保证内管中天然气输送的稳定性,避免温差较大出现内管内部气压波动较大的问题。同时,外管的设置还可对内管起到保护作用,在受到外力时,由于外管的存在的防护,避免内管发生形变,进而避免其发生泄漏。
