1110 Design Aspects

Protection against corrosion should begin at the design stage, that is, adopting a proactive approach rather than taking reactive measures after corrosion has occurred. Clear consideration to limiting metal/electrolyte interfaces and operating protective systems under optimum conditions rather than selecting maximum protection can lead to a reduction of up to 20% in the costs arising from corrosion. During a project there are various stages at which corrosion control considerations should be adopted, as shown in Table 11.17.
