Regarding the issue of excessive thrust bending moment at the top outlet of the stripping tower

As shown in the diagram: it is a pipeline at the top of the stripping tower, with an operating temperature of 240 degrees and a pressure of 370 kPa. The pipe diameter is DN350, the wall thickness is 9 mm, and the material of the pipe is 20# steel. Simulations have shown that the thrust and bending moments at the top of the stripping tower and at the outlets of the condenser exceed 10,000 units; according to SH/T3074 standards, these values should not exceed 8,000 units. I seek advice from experts on ways to reduce these thrust and bending moments.
If you connect them in such a straight line, it’s strange if they’re not big. Extend a few meters outward from the top of the tower, and then install two limiting thrust stops on the pipe section at the outlet.
Thanks for the tip, I’ll learn it :handshake
The standpipe is too short; the horizontal equipment can be rotated 180 degrees, or the direction of the pipeline at the tower’s outlet can be altered to increase flexibility.
If the layout permits, it is possible to consider placing the fixed ends of the tower and the heat exchanger on a straight line in order to reduce the displacement difference.
