Since it is impossible to measure the thermodynamics properties of all systems in nature, we must rely upon mathematical models to extrapolate the available experimental data. In order to develop such models, very accurate experimental data are necessary for selected complex mixtures, such as those that exist in natural gas. For this reason researchers must collect the most important and fundam...

The internal inspection of corrosion in large natural gas pipelines is a fundamental task for the prevention possible failures. Photos and videos provide direct proof defects. However, implementation this technique limited by fast robot motion poor lighting conditions, with high-quality images being key to its success. In work, we developed gas-driven pipeline endoscopic (GDPER) visual inner wa...

Recently, with large-scale use of natural gas and massive constructions of gas pipelines, more and more public concern is focused on pipeline leakage. The leakage caused by holes on gas pipelines generates economic losses to gas companies and causes risks to the environment and sometimes accidents. In order to detect and locate pipeline rupture immediately, the leakage detection method plays a ...

The accumulation of static charge in polyethylene pipes gas network systems is a familiar process, which paid attention to mainly prevent accidents on pipelines. incidents related electricity can occur both during assembly works (coil tapping) and the operation pipelines (gas venting, etc.). Despite fact that repeated attempts study this process have been made by major operating organizations, ...
