| 总结: | Oil and gas industry has been contributing as a largest government income and this
industry manage to control corrosion which causing wear failure in gas pipelines and
potentially cause substantial human and economic losses. The objective of this study is
to study the effect of H2S04 solution concentration electrolyte to corrosion behaviour of
the internal surface of natural gas pipeline by using Tafel Extrapolation Method. This
research starts with sample preparation where the sample from gas pipelines has taken
and cut into 1 Omm x 20 mm dimension. This sample has been tested in corrosion test
experiment to collecting and analysing the data gain from Tafel slope analysis, Optical
Microscopy (OM) and Scanning Electron Microscopy (SEM) to perform corrosion rate
and it effect on the surface morphology and microstructure. Due to the result of this
study, it is point out that corrosion rate increase with high concentration of H2S04 which
presence in natural gas composition. The data can be used to managing the pipelines
effectively and prevention method can be taken in order to extend the life span of the
pipeline. |
