Sep 09, 2021 · Sep 09, 2021 · Shell and tube heat exchangers are, simply put, a device that puts two working fluids in thermal contact using tubes housed within an outer cylindrical shell. These two integral pathways are usually built out of thermally conductive metals that allow easy heat transfer ( steel , aluminum alloys , etc.). Basics of Shell and Tube Heat Exchangers (With PDF)
Floating head heat exchanger is one of the most used heat exchanger. As shown in the name of it, in this design, one end of the tubesheet is fixed to the shell, while the other one can float freely inside the shell. Generally, both the shell and tube bundle are free of expansion, this permits no thermal stress is produced between shell and tube bundle, when the temperature difference of two medium is large. Graphite Heat Exchangers - Shell and Tube TypeShell-and-tube graphite heat exchangers are constructed from the following components:- Graphite tube in standard dimensions of 22/32, 25/37 and 36/50 mm - Standard graphite tube lengths up to 6 M - Two graphite tube sheets--one fixed and the other floating, relative to the shell - Large heat transfer areas of Shell and Tube Graphite Heat Exchanger (over 1,000 m2) - Low pressure drops
Floating-head exchanger:It consists of a stationery tube sheet which is clamped with the shell flange. At the opposite end of the bundle, the tubes may expand into a freely riding floating-head or floating tube sheet. A floating head cover is bolted to the tube sheet and the entire bundle can be removed for cleaning and inspection of the interior. This type of exchanger is shown in Figure 1.3. TYPES OF SHELL & TUBE HEAT EXCHANGERS2. FLOATING HEAD EXCHANGERS - In this construction, tube bundle can be removed from the heat exchanger shell for inspection & cleaning (of both sides) and replacement of bundle (using the old shell and channel). - During operation, the floating tubesheet floats/ slides inside the shell
Apr 21, 2021 · Apr 21, 2021 · Floating Head Heat Exchanger In the floating head exchanger, the tube sheet is not welded to the shell at the rear header end but is permitted to move or float. The tube sheet at the front header (fluid inlet end on the tube side) has a larger diameter than the shell and is sealed in a manner similar to that applied in the fixed tube sheet design. US4197907A - Floating head support system for shell and In a shell and tube heat exchanger having tubes connected to a floating head which is connected to a floating tube sheet by means of a split ring mounted on the tube side of the tube sheet during assembly of the exchanger, the improvement which comprises a shoulder bolt threaded into an opening in the head side of the tube sheet near the upper end thereof, said shoulder bolt extending outwardly from the face of said tube
Jun 14, 2021 · A shell and tube heat exchanger, in simple words, is a type of heat exchanger where the two working fluids exchange heat with the help of, as the name suggests, tubes and a shell. One of these is called the tube side fluid and the other is known as the shell side fluid.
