Measurement of Corrosion Pits in Steel Plates Using a Low-Field Squid Susceptometer

Abstract

Nondestructive evaluation methods are largely used for inspection of storage tanks and pipelines in the oil industry. The main goal is to detect and locate points of corrosion which can endanger the structural integrity or the watertightness, possibly causing leakage of oil to the environment, of catastrophic consequences. The occurrence of localized corrosion pits is of special concern, as they weaken the material strength and can initiate cracks at the pit cavity. In low-carbon steel samples, corrosion pits are typically shallow, roughly with the shape of a half-sphere [1].
