Tube-to-Tubesheet Connection Process Engineering
Rolling to 95% of tubesheet thickness is recommended. Rolling at or beyond the tubesheet thickness is not recommended—for it may damage the tubes. For moderate general process requirements (less than 300 psi and less than 350°F) tubesheet holes without grooves are standard.sp.info Can a tube be rolled to a tubesheet?Can a tube be rolled to a tubesheet?A reduction in wall thickness of 5% is sometimes used as an indicator of adequate rolling. 4. Hydrotest the shell side after the final rolling. In these cases, tubes can be rolled and then seal or strength welded to the tubesheet.Tube-to-Tubesheet Connection Process Engineering
How to seal heat exchanger tubes to tubesheets?How to seal heat exchanger tubes to tubesheets?The following procedure summarizes the requirements for seal welding heat exchanger tubes to tubesheets. 1. Use new tubesheets if possible. If old tubesheets are used, make as much like new as possible. After machining, degrease by steam cleaning. 2. Clean tube ends with tube polisher. 3.Tube-to-Tubesheet Connection Process Engineeringsp.info Why is the baffle cut horizontal in a heat exchanger?Why is the baffle cut horizontal in a heat exchanger?When the shell side heat transfer is sensible heating or cooling with no phase change, the baffle cut should be horizontal. This causes the fluid to follow an up-and-down path and prevents stratification with warmer fluid at the top of the shell and cooler fluid at the bottom of the shell.Shell and Tube Heat Exchangers Construction Details
What kind of baffle is used for shell side boiling?What kind of baffle is used for shell side boiling?For shell side boiling, the baffle cut may be either vertical or horizontal depending on the service. Other types of baffles are sometimes used such as double segmental, triple segmental, helical baffle, EM baffle and ROD baffle. Most of these types of baffles are designed to provide fluid flow paths other than cross flow.Shell and Tube Heat Exchangers Construction Detailssp.info SHELL AND TUBE HEAT EXCHANGERS
In order to allow the fluid to flow backwards and forwards across the tubes part of the baffle is cut away. The height of this part is referred to as the baffle-cut and is measured as a percentage of the shell diameter, e.g., 25 per cent baffle-cut. The size of the baffle-cut (or baffle window) needs to be considered along with the baffle pitch.
