摘要

An evaluation is described for a tube with manufacturing induced bending, resulting from installation in a tubesheet mis-drilled hole. Considerations include manufacturing processes such as tube installation and tube expansion plus evaluations of the resulting tube stresses using ASME B&PV Code Section Ⅲ rules. Also considered are operating issues such as potential interaction with neighboring tubes, tube vibration and wear, and the potential for accelerated tube corrosion. This is a companion paper to "ASME Section Ⅲ Stress Analysis of a Heat Exchanger Tubesheet with a Mis-drilled Hole and Irregular or Thin Ligaments".
