#404 - Heat Exchanger Design and Maintenance
Course Objective
Upon completion of this applications-oriented course, attendees will be able to evaluate the mechanical design of shell-and-tube heat exchangers and have an overall understanding of typical heat exchanger maintenance requirements.
Who Should Attend?
Individuals who are responsible for evaluating the mechanical design of shell-and-tube heat exchangers, or those responsible for their maintenance. Attendees should already have a basic understanding of ASME Code pressure vessel requirements prior to taking this course.
Course Description
This course discusses the mechanical design requirements of shell-and-tube heat exchangers for process plant applications based on ASME Code, TEMA, and API 660 requirements. It also highlights the primary features of air-cooled, double-pipe, and plate-and-frame exchangers. The following topics are covered:
