When calculating the tube sheet for SW6, the external pressure strain coefficient B curve exceeds the allowable limits
Thread Content
The heat exchange tubes in the heat exchanger are made of red copper T2. When using SW6 to perform calculations on the tube sheets, those calculations succeed, but when calculating the external pressure on the heat exchange tubes, the temperature value for the strain coefficient B curve exceeds the allowed range. I wonder, experts, how did you solve this problem? In the older version of the heat exchanger, the external pressure was not taken into account; after the recent upgrade, issues were detected in the calculation of the external pressure on the heat exchange tubes.
