A conscientious pipeline operator must monitor many aspects of possible operational pipeline deterioration. Some operators must deal with manufacturing defects known as 'hard spots'. Under certain conditions, hard spots may crack and fail. Cathodic protection may be a contributing factor in a failure. A magnetic flux leakage tool readily detects regions of elevated hardness (hard spots) in line pipe.
