Abstract: Disclosed in the present invention is a production pipeline having a pipe-in-pipe (PIP) structure, which can secure pressure resistance performance against external pressure in an erection step and secure insulation performance against water temperature in an operation step. The disclosed production pipeline provides a flow path of submarine resources by connecting a submarine oil well with an offshore oil rig or a land oil rig, by comprising: an outer pipe; an inner pipe which is placed inside the outer pipe and forms a space where submarine resources flow; and a porous channel unit which is placed between the outer pipe and the inner pipe by having a structure wherein gas charge is possible in order to form a gap between the outer pipe and the inner pipe into a gas charging state and a vacuum state. The disclosed production pipeline can secure the intensity of the outer pipe which resists erection load and water pressure by charging gas in the porous channel unit in an erection step, and can secure insulation performance between the outer pipe and the inner pipe by forming the porous channel unit into a vacuum state in an operation step, thereby preventing oil and gas mixtures flowing in the inner pipe from being cooled by the temperature of cold water.
