9.2 Damage Mechanisms 损 伤 机 理<br />

Understanding equipment operation and the interaction with the process<br />

environment (both internal and external) and mechanical environment is key<br />

to identifying damage mechanisms. Process specialists can provide useful<br />

input (such as the spectrum of process conditions, injection points etc.) to aid<br />

corrosion specialists in the identification of credible damage mechanisms and<br />

rates. For example, understanding that localized thinning may be caused by<br />

the method of fluid injection and agitation may be as important as knowing the<br />

corrosion mechanism.<br />
