Risk assessment is critical to ensure the safe operation of oil and gas pipeline systems. The core content such risk determine failure probability pipelines quantitatively accurately. Hence, this study combines MATLAB neural network toolbox adopts an Radial Basis Functions (RBF) with a strong non-linear mapping relationship build corrosion prediction model for buried gathering transmission pipe...

Low-carbon steel is widely used in industrial pipelines, and corrosion studies are focused mostly on erosion-corrosion, its prediction control. In this paper, the rate pipelines modeled using a flow loop measured by linear polarization resistance method (LPR) 3-electrode setup for API-5L-X65 QT steel. Optical microscopy SEM conducted to examine surface of sample products. The effect NaCl concen...

Carbon dioxide (CO2) is one of the corrosive element which exists in oil and gas industries. To prevent CO2 corrosion on carbon steel pipelines, amine-base solvent caustic solutions are commonly applied. Accordingly, effectiveness amine base to reduce risk becomes key parameters determining service lifetime pipelines made steel. In this research, rate A106 Gr B combined with saturated solution ...

External corrosion was identified as one of the main causes of pipeline failures worldwide. A solution that addresses the issue of detecting and quantifying corrosivity of environment for application to existing exposed pipelines has been developed. It consists of a sensing array made of an assembly of thin strips of pipeline steel and a circuit that provides a visual sensor reading to the oper...

Abstract The prevention of gas overrun in the panel is one key issues on green mining. In this paper, a physical goaf model was established based geological production conditions coal seam mine Henan Province, and combined drainage technology by burying spilling pipeline upper corner proposed. Fluent software used to simulate changes mass fraction flow field distribution when extracted from wit...
