Tube Sheet Heat Exchangers of the big advantages of using a shell and tube heat exchanger is that they are often easy to service, particularly with models where a floating tube bundle where the tube plates are not welded to the outer shell is available. Fixed Tube Sheet Heat Exchangers used on fixed tube sheet heat exchangers. Heat Exchanger:Conical shell and Nozzle Reinforcement the fluid outside the tubes. Tube sheet can be fixed to the shell or allowed to expand and contract with thermal stress. In the later design an expansion blows is used or one tube sheet is allowed to float inside the shell. Heat exchanger studied here has fixed tube sheet without bellows and without floating head.
Tubesheets of Heat Exchangers. Tubesheets are usually made from a round flat piece of metal with holes drilled for the tube ends in a precise location and pattern relative to one another. Tube sheet materials range as tube materials. Tubes are attached to the tube sheet by pneumatic or hydraulic pressure or by roller expansion.

Insert the tapered plug into the tube end or tube sheet hole to be plugged. Set the tube plug into the tube or sheet hole as far as it will go. To complete the plugging process, drive the plug into the tube not more than 1/16 to create the seal. Driving the plug too deep may damage the tube sheet hole ligaments, causing the adjacent tubes to Tubing Data Sheet (MS-01-107;rev U;en-US;Catalog)Tubing Data 3 TUBING DATA Table 1Fractional Carbon Steel Tubing Allowable working pressures are calculated from an S value of 15 700 psi (108 MPa) for ASTM A179 tubing at 20 to 100°F (28 to 37°C), as listed in ASME B31.3.
DEEP HOLE DRILLING MACHINES Horizontal multi-spindle machines for deep drilling tube sheets Deep holes drilling machines to drill plates of heat exchangers for petrochemical, electric and nuclear power.
