I drilled en reamed hundreds of pipeplates and baffles for heat exchangers. It was avery responsible job, no mistakes where allowed because of the mostly very expensive materials!!

@ryanstruk1: Rolled is a "slang" for expanding since the expander has rollers on them. The tubes are expanded with each revolution of the mandrel. The mandrel is tapered and the slots in the cage that holds the rollers is angled. So when it is rotated the mandrel draws itself in and the rollers rotate and expand the tube out. We expand until the tube wall thickness is reduced by 4-5%. That is not teflon, it is "Lube-a tube" tube expander lubricant that is water souluble.

It looks like an oil cooler for an air compressor or skid unit. Instead of brazing the tubes to the baffles, we typically use tierods in the stationary tubesheet & cut spacers. We've retubed these before and found the shellside velocity had stacked the baffles on one end. all in all it's a great looking bundle. We use crisco some times while rolling also.

Tubes are free on baffles, which direct flow in heat exchangers. Tubes are expanced to tube sheet at the length of 90% of tube sheet thickness if I remember right. For oil industry we made on previous workplace tube bundles with tube sheets from about 40mm thickness to +300mm. Tubes are easily removed if needed. We used modified Hss-drillbit on magnetic drilling machine or on radial drilling machine.

They are rolled with an expander. The drill is an electric roll motor and it is connected to a controller that measures amperage draw. The controller is set to reverse at the correct expansion. The correct expansion is 4 to 5% wall reduction. The technician measures the ID of the tube sheet, the OD of the tube, the ID of the tube and the wall thickness of the tube. Then does simple math to calculate what the ID should be after expansion. Set controller to reverse at that ID thru trial and era.

@engineerdr These are baffles, their function is to lengthen the path of water flow between tubes. It also makes the flow more turbulent by passing the water perpendicularily to the tubes, creating vortices. This is a shell and tube HE without the shell. A full plate would block the flow.

@evandrogaio7003

It depends of how much heat you want to exchange.. Its a project parameter. Usually its known the fluids. For the primal fluid, the one you want to cool or heat, is known the initial and final temperatures and for exchange fluid (usually water) is known the initial temperature. From a energy balance you will be able to find the final temperature and how much heat was exchanged. You also need to know the flow conditions and they properties as Re, Pr, u and Nud. You should know the flow rate of the primal fluid and estimate the needing exchange fluid flow rate. Using heat exchange knowledge, you will be able to find the total length needed for the tube. Knowing the length, and using standards cooper diameters you can decide the diameter and length of the shell based in your real conditions (space).
