Materials and Fabrication Selection
Chapter OverviewA
s chemical process plants turn to higher temperatures and flow rates to boost
yields and throughputs, selection of construction materials takes on added
importance because these severe conditions intensify corrosive action. Fortunately,
a broad range of materials is now available for corrosive service. However, this
apparent abundance of materials also complicates the task of selecting the “best”
material because, in many cases, a number of alloys and plastics will have sufficient
corrosion resistance for a particular application. Final choice cannot be based simply
on selecting a suitable material from a corrosion table, but must be based on a sound
economic analysis of competing materials.
The purpose of this chapter is to provide the design engineer with a working
knowledge of some of the major forms and types of materials available, what they
offer, and how they are specified. With this background, the engineer can consult a
materials specialist during the early stages of the design to establish the materials that
best meet the process conditions. |
