How to creat this mode.

Good day to you Zhu Jun, 

Is this a heat exchanger or a pipe welded into the end of a vessel

Are you using AutoPIPE or AutoPIPE Vessel?

If using AutoPIPE, continue below. 

1. Model large vessel piping. Where top of Vessel is weld location to smaller pipe (ex. A02).

2. Insert new segment for smaller dia piping based on end of vessel node point (ex. B00). Then insert run (ex. B01) to exact elevation where pipe is to be welded to vessel (ex. A02) and continue modeling smaller pipe as needed.    

3. Insert Node Link anchor between Smaller Pipe and Vessel at the weld location (ex. B01 to A02).

4. insert Joint Type and  User SIF as needed

5. Done!!
