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.
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.
