Heat Exchanger Channel with a Body Flange

thread1259-258595

Heat Exchanger Channel with a Body Flange

Heat Exchanger Channel with a Body Flange

(OP)
I am attempting to build the following rear (bottom)channel assembly in Compress:

Tubesheet (integral with shell and channel)
24-inch long channel
Body Flange
36-inch long channel
Ellipsoidal head with 1" SF

Any suggestions on how to build this in the Compress Heat Exchanger module?

RE: Heat Exchanger Channel with a Body Flange

Your question is a little unclear.  Are both tubesheets fixed, or is the rear a floating tubesheet?  Just (1) body flange?  One on each channel?

To build any part of an exchanger in Compress, the only way I know how to do it right is to build the whole exchanger.

RE: Heat Exchanger Channel with a Body Flange

(OP)
This is an existing exchanger with both tubesheets fixed.  The top tubesheet is integral with the shell with a bolted on bonnet.

As stated previously, the bottom tubesheet is integral with the shell and a cylinder on the tubeside.  The cylinder on the tubeside (24-inches long) is attached to a body flange.  The mating body flange is then attached to 36-inch long cylinder with an ellipsoidal head closure.

I have attempted to build the entire exchanger in the Compress heat exchanger module.  The issue I am having is bottom tubeside assembly that is described in the second paragraph.  From what I have tried, Compress does not seem to like this configuration (cylinder/body flange/cylinder/head).  Perhaps Tom or others may have some ideas.
