You have already given operting temperature for shell and jacket. It is steam on jacket so we can consider same temp. for In & Out on jacket side.  Please specify inlet temp. on shell side. We are assuming 110 specified by u is outlet temp on shell side.  Please confirm.   

The temperatures across the jacket and process side film ( entry and exit temperatures) are required to check if an expansion bellow is required. The design calculations cannot be submitted for aproval from AI unless we get this data.
 
We would like to get a favourable response  at least on above issues in today's coneference meeting.
