Design for Corrosion Control |
Corrosion is broadly defined as material deterioration by chemical or electrochemical attack. Corrosion is a natural process and the corrosion process is complex. An understanding of the basic corrosion mechanism is essential in designing equipment for corrosive service. Materials are thermodynamically unstable and potential corrosion problems and failures are unavoidable for poor choice of material or configuration by the designer, or carelessness on the part of the user. Lack of corrosion awareness can instigate corrosion problems during the design of a project. Neglecting to resolve the potential corrosion problems during the design phase will inevitably cause a significant direct cost in future - corroded equipment and unexpected shutdowns or equipment replacement.
As corrosion consultants, CMS are in a position to help client’s design team integrate preventive actions into overall designs and the design adapted to make the most effective use of the needed corrosion control measures. Corrosion control is primarily driven by economics, and cost can be predicted and balanced. Our engineers are certified by NACE as designers for corrosion control, we ensure that the most appropriate corrosion control measures are evaluated and incorporated into the final stage.
We understand the interactive effects of corrosion and design, and have a through knowledge of matching materials performance to service environments. We know what we can do to reduce the high cost of failures caused by corrosion, viz:
· Understanding Losses from Corrosion
· Equipment Service Life Factors
· Selection of Materials of Construction
· Corrosion Rate Determination and Allowance
· Corrosion Rate Classification
· Design Solutions to Corrosion Problems based on type of Corrosion
· Design Solutions to Corrosion Problems based on Fabrication Techniques and Environmental Factors
· Specifications and Guides
· Specifications and Guides Corrosion Control Techniques
