Application area in chemical and oil and gas industry it is necessary to heat pipelines of several kilometers long. Due to the fact that maximum permissible connection lenght of one heating section is about 200 meters, heating of long pipelines by standart heating cable is limited.
Principle of operation Heatline-SKIN
Skin-pipe is installed on pipeline so as to provide reliable heat contact with principal pipeline. SKIN-conductor is placed into ferromagnetic steel SKIN-pipe. On the distal end SKIN-conductor connects wich SKIN-pipe in a short circuit. SKIN-pipe is grounded on both ends. On the near end voltage of commercial frequency is imposed between SKIN-conductor and SKIN-pipe. The currents of reversed direction flow near SKIN-conductor and SKIN-pipe,and in the SKIN-pipe the current flows near inner layer of pipe which is about 1 mm thick at that. Also potential of outer surface of SKIN-pipe remainz zero. Due to magnetic characteristics of SKIN-pipe there is SKIN-effect which leads to greater visibility of pipe resistance than on the direct current. Due to small thickness of SKIN-layer principal heat emission occurs in steel pipe. At right installation of SKIN-system 60-80% of heat is evolved in SKIN-pipe and only 20-40% in SKIN-conductor is transferred to heated pipeline. Fixation of SKIN-pipe to principal pipe is carried out wich the help of steel hoops and special tool or spot welding.
