高压气体输送管腐蚀裂纹产生的原因及防止德国杜伊斯堡市的曼内斯曼公司防腐蚀研究所研究讨论了阳极氧化或氢腐蚀所导致的高压气体输送管裂纹产生的原因。该研究表明，钢管表面形成细小的沟纹是因阴极保护层被破坏引起。而阴极保护层的被损坏则是高压气体输送管的外涂层不... Causes of Corrosion Cracking in High Pressure Gas Delivery Tubes and Their Prevention The Mannesmann Institute of Corrosion Protection in Duisburg, Germany, studied the causes of cracks in high pressure gas delivery pipes due to anodic oxidation or hydrogen corrosion. The study shows that the formation of small grooves on the surface of the pipe is due to the destruction of the cathode protection layer. The cathodic protection is damaged is the high-pressure gas pipe coating ...
