Effects of Sleeving Closed Feedwater (PDF, 931KB)
Download Excel Spreadsheets for Feedwater Heater Sleeving Calculations discussed in the April 2004 issue of Power Magazine Pressure
drop calculation with full length sleeves Download Excel Spreadsheets for Calculating Percent Wall Reduction
for Expanded Tube Joints Download Excel Spreadsheet for Calculating Bypass flow and hole size in pass partition for bypassing feedwater flow by means of a hole in the pass partition to be used when the number of plugged tubes causes feedwater pressure drop to reach or exceed the established limit. The calculation used in the spreadsheet below was derived by Stanley Yokell during the writing of ”Tubular Heat Exchanger Inspection, Maintenance and Repair”, by Carl F. Andreone and Stanley Yokell, McGraw-Hill, New York, 1997. MGT wishes gratefully to acknowledge the work and suggestions
of Linda Riley of Kansas City Power and Light Company (Great Plains
Energy) that made the presentation clearer and more understandable. Note: The above downloads require a recent version of MS Excel software on your PC. |

Stanley Yokell has submitted his paper, “On Hydrostatic Testing Heat Exchangers” to the Journal of Pressure Technology. The ASME has assigned PVT-8-1122 to the paper during consideration of acceptance and peer review if accepted for publication. Here is the abstract. ABSTRACT This paper discusses the requirements of Section VIII Division 1 of the ASME Boiler and Pressure Vessel Code (the Code) for hydrostatically testing shell-and-tube heat exchangers. It uses an approximate calculation method to delmostrate that the common practice of using pressure gage indications of pressure loss to determine if there is a leak from the tube side to the shell side when the back face of the tubesheet is not visible is flawed and does not meet the basic no-leak requirement of the Code.
Carl Andreone, P.E., Fellow of the ASME is unavailable at this time. Please address your inquiries to Stanley Yokell, P.E., Fellow of the ASME.
