| description | The invention provides a novel composite directly-buried steam heat preservation pipe network system which is formed by connecting a plurality of pipelines in series, and each pipeline comprises a plurality of steam heat preservation steel pipes which are sequentially connected end to end. An inner heat preservation layer, a middle steel sleeve, an outer heat preservation layer and a protection shell are sequentially arranged on the periphery of the steam heat preservation steel pipe of each pipeline. A composite compensator is connected between the two steam steel pipes of the adjacent pipelines, and a partition compensator and a main corrugated pipe compensator which are arranged on the steam steel pipes in a sleeving mode are sequentially arranged in a shell of the composite compensator. The steel sleeve is arranged in the radial middle position of the heat preservation layer shell of the directly-buried steam heat preservation pipe and the steam steel pipe interlayer, a barrier is formed, and the situatio |
