Title:
SPIRALLY HEATING SUBMARINE PIPELINE
Document Type and Number:
WIPO Patent Application WO/2020/071628
Kind Code:
A1
Abstract:
The present invention relates to a spirally heating submarine pipeline which can prevent wax and hydration from occurring within a submarine pipeline during fluid transportation from a subsea production plant. More specifically, the present invention relates to a technology for a spirally heating submarine pipeline wherein an electric heating wire having a semicircular cross-sectional shape is laid in a spiral structure while being arranged inside a pipeline so as not to protrude out of the outer circumferential surface of the pipeline, whereby thermal conductivity and fluid flow in the pipeline can be improved.
