"Closed Loop Corrosion Test Rig" Equipment for Flow Assisted Corrosion Study

The closed-loop corrosion test rig is developed as equipment to study the electrochemical and corrosion behavior of metallic materials under flow simulated media with controlled dissolved oxygen and different flow rate at a constant temperature. This study is required for the pipeline material evaluation specifically dealing with oil, marine water, and other liquid media.

"Closed-loop corrosion test rig" is indigenously designed by CSIR-NML for the first time. The equipment has the facility to control and monitor dissolved oxygen (50-5000ppb), the flow rate of the media during the experiment. Provision for extra sensors for monitoring other parameters. Equipment is attached with two types of a test rig for metallic coupon exposure as well as electrochemical studies using online potentiostat underflow conditions.
