Corrosion of Natural Gas Transmission Line: a Case Study
Abstract:
Natural Gas is one of the important fossil fuels used in the Power Generation industry. During the year 2000, the Cathodic Protection potential survey revealed that the potential at a road cross is less than the acceptable minimum value indicating that the current given to the piping system is diverted to non piping system component. Hence a thorough inspection was performed and the causes were identified. Based on the information gathered from the first inspection, a complete survey of the entire length of pipe line was carried out and recommendations were given to the management with repair priorities. This case study details the inspection method used to assess the condition of the natural gas line which is partially buried and the repair methods suggested.
