Mar 05, 2020 · U tube heat exchanger. The tube bundle consists U shaped tubes. Both ends of U tube are fixed in the same tube sheet. Thermal expansion resulting due to the temperature difference between. shell and tube material is taken care off by U bends. U tubes can expand or contract freely and uniformly. It performs the same function as floating head.
In an effort to reduce thermal stresses and provide a means to remove the tube bundle for cleaning, several floating rear head designs have been established. The simplest is a "pull-through" design which allows the tube bundle to be pulled entirely through the shell for service or replacement. Selection of Shell & Tube Heat Exchangers TEMA Types Sep 05, 2020 · Floating head design allows for differential thermal expansion between the shell and the tube bundle. Shell circuit can be inspected and steam cleaned. If it has a square tube layout, tubes can be mechanically cleaned Higher surface per given shell and tube diameter than pull-through designs such as AET, BET, etc.
May 09, 2019 · Shell & tube heat exchangers are very popular and commonly found in industrial use. This is mainly due to their versatility. A shell and tube exchanger consists of a shell, tube bundle and two heads or caps at both ends of the shell. Shell Heat Exchangers, Tube Heat Exchangers, Shell & Tube Tubes can be straight or 'U' bundle. Fixed-Tube Sheet Design. Full-Through Floating-Head Design. Split-Ring Floating-Head Design. Bayonet Tube Design. Material Heat Exchangers are fabricated in Hastealloy, Inconel, all grade of Stainless Steel & Carbon Steel & any other weldable material operating in moderately high pressure and temperature range.

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.
Floating head heat exchanger is widely used for the service where the temperature is high between the shell and tube bundle, or the dirty service, like the petroleum refinery. With high reliability and wide adaptability, floating head heat exchanger has accumulated a wealth of experience during the long term using process, and promoted its
