Abstract
Independent power supply source for the station of cathodic protection of pipelines against corrosion
Highlights
PROPOSED ENGINEERING SOLUTIONSThe most common method of protecting equipment made of carbon, low- and high-alloy and high-chromium steels, tin, zinc, copper and copper-nickel alloys, aluminum, lead, titanium and their alloys from electrochemical corrosion is cathodic protection
As a result of the experiments using a flat thermoelectric section, it was found that when an average temperature difference between the heating and cooling media is 100° C, an electric current with the voltage U = (1.2-1.5) V, the current intensity I = (0.08- 0.1) A and the power P = (0.2-0.22) W can be generated
A laboratory experiment using an experimental setup in which a pipe with a length of 0.5 m and a diameter of 50 mm was used as the pipeline was carried out
Summary
PROPOSED ENGINEERING SOLUTIONSThe most common method of protecting equipment (including pipelines) made of carbon, low- and high-alloy and high-chromium steels, tin, zinc, copper and copper-nickel alloys, aluminum, lead, titanium and their alloys from electrochemical corrosion is cathodic protection (protection by means of external current). Based on the use of the thermoelectricity effect, engineering proposals of designing an independent power supply source for CPS were developed at the Department of Heat, Gas and Water Supply of the Southwest State University (Kursk, Russia) [04-06].
