Describes grooving corrosion attack on welded steel pipe used as pumping columns in South African mines. Outlines metallurgical examinations, chemical analyses, electrochemical studies and residual stress tests made to determine exact cause of the corrosion. Briefly discusses preventive and control measures being used and tested. Photographs, tabular data and graphs. Concludes that grooving corrosion was casued by residual stresses in pipe. 4.6.8
