Stay ahead of corrosion—let’s get started!
The oil and gas industry considers corrosion as the primary threat to asset integrity. To mitigate corrosion, it's crucial to conduct corrosion studies during the engineering phase of projects. Key issues addressed include identifying potential corrosion threats, assessing corrosion rates, selecting materials, and developing a corrosion control philosophy. Material selection should prioritize minimum life-cycle cost while ensuring adequate performance throughout the design life. A poor corrosion study, with overly conservative or underestimated corrosion rate assessments, can lead to either unnecessary project costs or immediate post-commissioning corrosion issues, respectively. The impact of such assessments on project costs, particularly procurement costs, is significant in the oil and gas sector. Various corrosion models exist to assist engineers in assessing CO2 corrosion rates, but they yield differing results due to differing development philosophies. While most models predict worst-case scenarios well, they vary widely when considering complex effects. This variance is primarily due to the arbitrary nature of empirical correction factors used to account for complicating effects. In addition to uncertainties from corrosion models, human errors contribute to false predictions, further undermining reliability. While some uncertainties are inevitable, identifying and addressing human errors can enhance the reliability of corrosion rate assessments and material suitability. The material provided aims to provide knowledge about material selection methods, models, identify common errors during corrosion rate assessments found in corrosion study and materials selection reports, recommending precautionary measures to mitigate them.
