ASME STP-PT-053

The purpose of this document is to justify and provide technical criteria for the rules of Part UHX of ASME Section VIII Division 1, 2010 Edition, devoted to the design of U-tube, Fixed and Floating head Tubesheet Heat Exchangers. Confirmation and documentation of the basis for UHX-rules is important for the SG-HTE members for future reference and developments or if additional confirmation or comparisons are required. It will be a valuable reference for early career engineers that are using the UHX rules or becoming involved in Code developments of such rules in the future.
