摘要

The inner surface of pipe plays a crucial role in top of line corrosion when condensation of droplet takes place. Condensation over inner periphery of pipeline takes place by droplet formation due to differential temperature inside the pipe and external environmental factors. To understand the change in corrosion rates with respect to droplet flow and temperature [40℃, 60℃ and 80℃], a rig with curvature 80mm which simulates top of line corrosion is designed to carry out experiments at 0°, 15° and 30° inclinations in fixed 3 litre beaker. Droplet formation on the sample as well as on perpex surface has been captured at different temperatures to understand the droplet size formation. Corrosion rate calculation is done my weight loss methods which are generally preferred in on site analysis instead of electrochemical measurements. Surface analysis is carried out with the help of optical microscope and optical profilometer where corrosion rate, inclination were correlated to average surface roughness. *Presently Working at Welspun Corp.
