Objectives The aim of this project is to understand and develop a method to assess the threat of internal stress corrosion cracking (ISCC) in pipelines previously used to transport manufactured gas. Success of this project will be the development of a methodology to identify whether a pipeline has the potential to contain ISCC. In addition this should provide information on the different types of manufactured gas, and identify, where possible, which areas manufactured what type of gas in the UK.
Abstract High pressure pipelines that were previously used to transport manufactured gas (e. g. town gas or reformer gas) can be subject to Internal Stress Corrosion Cracking (ISCC). There are currently no practicable industry guidelines for identifying whether a pipeline has the potential to contain ISCC and to assess the significance of any cracking found, this project will assess the extent of the threat of ISCC to the pipelines owned and operating by the participating GDNs, which will enable the requirements and benefits of further research to be confirmed. This project will undertake internal inspection of pipe samples retrieved from Lamesley to confirm the presence of ISCC and use the results to develop a threat assessment algorithm to enable identification of those pipelines that are most likely to contain ISCC, along with guidelines to identify where along the pipeline route that the ISCC would most likely be located.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
