Floating head heat exchangers are suitable for heavy duties associated with high temperature and pressure and large temperature differences. Fouling fluids can be handled because cleaning of tubes from inside and outside is possible. These units are widely used in petrochemical plants and chemical industries. Advantages Tube bundle can be removed for inspection. Mechanical cleaning of the outer surface of tubes is easily possible. Since tubes are straight, individual tubes can be replaced. Inside tube surface can be cleaned without removing the tube bundle. No limitation on number of tube side passes. It is very costly. It has a large number of gasket joints. You may also like...

Split-Ring The split-ring type of floating head heat exchanger meets the challenge presented by the pull-through bundle. This design bolts the floating head bonnet onto a split backing instead of onto the tube sheet. This feature of the split-ring type allows for the inclusion of most of the tubes that are missing from the pull-through bundle. The split-ring type also has the "pull through" feature associated with the pull-through bundle type of floating head heat exchanger. Outside-Packed Lantern Ring The outside-packed lantern-ring type of floating head heat exchanger lacks positive sealing, and is thus much more prone to leakage than either the pull-through bundle type or the split-ring type. This makes it somewhat unreliable in situations dealing with high pressure or hazardous fluid. Furthermore, it only contains two tubes. Outside-Packed Stuffing Box The outside-packed stuffing box type of floating head heat exchanger also lacks positive sealing, and is thus also prone to leakage.
Devices are designed to heat liquids and gases in industrial processes refining, petrochemical, chemical, oil, gas and other industries and are manufactured according to the ТS 3612-023-00220302-01. Description Specification Example of designation The cooling environment in refrigerators and condensers is water or another nontoxical, not explosive and not flammable liquid with a boiling temperature with a pressure of 0, 07 MPa over 60°С. Devices can be used in a climatic regions with temperate and tropical climates. Climatic modification «U» и «Т», category of a product 1 according to GOST 15150. The devices are designed to be installed in geographic areas seismicity to 7 points in the Russian Federation adopted on 12-point scale. When choosing vehicles produced heat engineering calculations, as well as selected materials that provide resistance to the corrosive effects of environments.

Best Floating Head Heat Exchanger for Sale 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. In addition, it is easy to inspect and clean mechanically the heat exchanger as the tube bundle can be removed absolutely. 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 development constantly. So far, among all kinds of heat exchangers, floating head heat exchanger is still in a leading position.
