Description

technical field [0001] The invention relates to the field of corrosion electrochemistry, in particular to a top corrosion electrochemical testing device under high temperature and high pressure environment. Background technique [0002] In recent years, with the increasing development of oil and gas fields, many failure accidents have occurred in pipelines transporting oil and gas, and top corrosion is an important part of them. Therefore, research on electrochemical in-situ testing of top corrosion under high temperature and high pressure conditions has also attracted much attention. . So far, there is no electrochemical corrosion equipment for studying the wet top of pipeline steel, and the present invention is a comparatively advanced equipment in this respect. In the process of oil and gas industrial exploitation and transportation, the corrosive media mainly involved include CO 2 Such acid gases and water and some organic acids contained in it. Carrying out high temp...
