Default surfaceAutoPatch generate internal faces so SHM doesnot read the whole CAD

rsa is on a distinguished road

I am trying to mesh my geometry which is bunch of pipes sometimes crossing each other with SHM. I have a CAD obj file and use surfaceAutoPatch command with angle of 91 to get the inlet and outlet. the problem is, the angle of 91 generate some interfaces, hence, separating it from the rest of the system. I should emphasize that I am not talking about baffles. I am trying not to have any internal faces. so when I try to mesh the geometry with SHM it becomes either/or since those internal faces have in a way split the geometry into three separated section in the eyes of SHM! Is there anyway to prevent it?
