Abstract
Disclosed is a spirally heating submarine pipeline including: a conduit which transports a high temperature high pressure fluid from a submarine oil well; and a heating unit disposed in a spiral structure inside based on an outer circumferential surface of the conduit. The heating unit includes an electric heating wire that is installed along the spiral structure to generate heat; a heat insulator that is installed in the form of fully surrounding the electric heating wire and preserves the generated heat; and a heat insulating cap for isolating the heat insulator from the conduit or the heat insulating layer and is provided so as to increase the temperature of the flow in the pipe to prevent the production of a pipe flow interfering material when the fluid is transported in the conduit.
