SUMMARY:

Internal corrosion is one of the main failure mechanisms in oil and gas (O&G) pipelines. In order to protect the integrity of the pipelines, several researchers are dedicated to reproducing in the laboratory the environments to which the pipelines in the O&G sector are constantly exposed. Currently, the rotating cage (GR) of the ASTM G170-06 standard is one of the most used methodologies for testing the vulnerability of materials in corrosive media or the efficiency of corrosion inhibitors under turbulent flow regimes. However, the GR is a very conservative methodology and there are several factors responsible for this conservatism, for example, the non-uniformity in the loss of mass in the specimens. The objective of the present study is to evaluate, through a computational study, changes in the geometric attributes of the GR of the ASTM G170-06 standard, in order to verify the possibility of obtaining a more uniform distribution of the shear stresses in the specimens.
