Heat Exchangers (UHX), this online course begins with a brief explanation of the various types of heat exchangers, especially those an Authorized Inspector may encounter. From there the course concentrates on the three types of ASME Section VIII Shell-and-Tube heat exchangers: U-Tube, Fixed Tubesheet, and Floating Tubesheet. In each case, the course first describes many of the general design considerations and characteristics. Then, it goes into specific design configurations and the calculations for each type of Shell-and-Tube Heat Exchanger. The course concludes with testing, marking, and reporting requirements.
