The present invention offers some general specifications for the design, assembly, and adaptation of a rotating cylinder electrochemical cell into an autoclave, of a high temperature and pressure system for corrosion studies that simulate operating conditions in pipelines, as well as the operation and safety of an autoclave to evaluate the electrochemical process of metal surfaces exposed to aggressive aqueous solutions. The electrochemical cell consists of an array of three electrodes that include a rotating cylinder electrode designed to operate hermetically, a reference electrode and an auxiliary electrode. The rotating cylinder electrode is considered to be the working electrode, where the oxidation and electrochemical reduction processes are studied. However, the use of the method described in this work can be extended to other testing environments and materials by taking into account the physical and chemical properties of the fluids and materials to be used in order to avoid any risk for the operator.
