Cathodic Protection of Metal Surface Inside Pipe Filled with Molten Salt
This invention provides an electrochemical method for detecting and arresting corrosion at the metal-molten salt interface, a location that, until now, was difficult to treat. While many of the pipes used in transfer of molten salt are resistant to corrosion on the exterior, this technology is the first to treat the interior of the pipe. Its novel design...
