Electrochemical probes for corrosion monitoring in hydrogen sulfide systems and methods of avoiding the effect of electron-conducting deposits

摘要: Electrochemical probes for corrosion monitoring in an environment that may cause the formation of electron-conducting deposits and method making such were described. The have long exposed electrodes. Except tip section, all surfaces electrodes are coated with a coating or covered electrically insulating tubing, so only section has uncovered metal serves as active areas tubing material is cannot easily form on its surfaces. Because electrical bridging between any two requires deposition evenly distributed layer along path from one area to other area, surface reduces possibility short-circuiting These especially suitable applications systems containing hydrogen sulphide (H 2 S).
