Tube spacing at split-pass partitions from heat exchanger data sheet
Thread Content
The heat exchanger data sheet provided by the foreign company does not indicate the tube spacing at the split-range partition plate in the pipe layout diagram. Where is this parameter reflected? Is it the data in the red box in the attached picture?
Not less than the tube spacing + the width of the dividing plate groove. In the figure, 24+12.66=36.66. Let’s take 38.

The data in the red box is the width of the dividing plate groove. The distance between tubes on both sides of the partition can refer to GB/T151-2014.
