Tube sheet calculation and bolt material in SW6 software
Thread Content
Dear seniors: When using the SW6 calculation software to determine the thickness of heat exchanger tube sheets, if all other parameters remain unchanged but the material of the main bolts differs, why does the calculated thickness of the tube sheet vary?
Under pre-tensioning, different bolt materials result in different calculated bolt loads; consequently, the flange torque varies, and the required thickness of the tube sheet also changes. The higher the strength of the bolts, the thicker the tube sheet should be, presumably.
