ELECTRICALLY HEATED FLUID TRANSPORTATION PIPE |
摘要 |
The invention relates to a heated pipe for the transportation of a fluid comprising:
a fluid transportation casing,one or several electric heating cables each arranged along the transportation casing, each cable comprising an electrically conductive core arranged in an electrically insulating and thermally conductive sheath,a thermally insulating material applied onto said heating cable or cables and onto the transportation casing,an external casing arranged around the thermally insulating material and made integral with the transportation casing in a sealed manner so as to define at least one annular space enabling its pressure to be reduced, the pipe additionally comprises means to reduce partial electrical discharges between said heating cable or cables and the transportation casing. |
