摘要
Abstract
In order to analyze the leak reason of the heat exchange tube which is made of 12CrlMoVG,the appearance of corrosion, metallographic structure, chemical composition of the tube material and the corrosion products,and service environment have been analyzed. The results show that the uniform corrosion which induced by the Oxygen and high temperature vapor occurred. The tube wall has been partially perforated in the serious corrosion area. The prevention methods were proposed for this equipment.关键词
