GB151-2014 Shell and tube heat exchangers.
Thread Content
According to 6.3.4.1 of GB/T151-2014, for shell-and-tube exchangers with axial inlet nozzles, the minimum depth at the midpoint of the nozzle shall not be less than one-third of the inner diameter of the nozzle. What does that mean?

Thank you, expert. After hearing what you said, I think you’re right too.
The distance from the lowest point of the intersection line between the nozzle and the tube sheet to the centerline of the tube sheet is not less than one-third of the nozzle diameter
