Pipeline for thermal fluid and method for piping thereof

摘要

The present invention relates to a transport tube that can preheat the inner tube to force tensile stress on the inner tube itself to prepare for high temperature steam and high temperature fluid, and to transport heat fluid stably. The present invention relates to a transportation pipe piping method that can be preheated simply by hot water and steam to quickly and accurately control tensile stress by force.;The piping method of the heat fluid transport pipe is a step of forming a pipe line after setting the position to be piped in order to embed the transport pipe underground; Continuously arranging transport pipes having a minimum unit length by a predetermined length in the pipeline to interconnect each other by a predetermined length to form a unit transport pipe; Evacuating the inner tube of the unit transport pipe; Preheating the inner tube by supplying hot water and steam at high temperature to the evacuated inner tube; Connecting the inner tube and the outer body of the preheated and expanded state to be integrally connected to each other to complete a unit transport tube; And interconnecting the unit transport pipes to a set length and then covering the soil in the pipeline to complete the piping work.;Heat Fluid, Piping, Inner Tube, Exterior, Transport Pipe
