Methane is one of the most serious greenhouse gases contributing to irreversible climate change. The contribution of methane emissions from leaking pipelines and the expected increased throughput through the pipelines prompted the natural gas industry to set a goal of reducing emissions by 50% by 2010. The integrity of the pipelines is critical to the safety of the gas transportation infrastruc...
