A floating head heat exchanger is one of the most commonly used heat exchangers. As shown in its name, in this design, one end of the tube sheet is attached to the shell, while the other can “float” freely inside the shell.
Normally, both the shell and the tube bundle are free from expansion, thus causing no thermal stress between the shell and the tube bundle when the temperature difference of the two mediums is large. In addition, the heat exchanger is easy to inspect and clean mechanically because the tube bundle can be removed at all.
Floating head type heat exchanger produced is of the large heat exchange area and handling capacity. It can bear high pressure and temperature. It uses argon welding equipment and electro-polishing treatment between shells and tubes. With strict inspection and testing procedure, it is a nice product for heat exchange of fluid media in industrial production.
Floating head heat exchanger tube plate is fixed between the shell and the tube box, another end of the tube plate can move freely in the shell,and when the tube is heated, the tube bundle together with the floating head can be adjustable freely along with the axial , eliminate the temperature difference stress completely.
Floating head type heat exchange is composed of floating tube plate, hook ring and floating head end cover, It’s a kind of releasable connection , and the tube bundle can be extracted from the shell, which is convenient for cleaning within the tube.
Floating head heat exchangers are widely used for service where the temperature is high between shell and tube bundle, or dirty service such as petroleum refinery. With high reliability & wide adaptability, the floating head heat exchanger has accumulated a wealth of experiences during the process of long-term use and has promoted its development continuously.
Oil refining, petrochemical , natural gas chemical, coal chemical, shale oil , synthetic resin and plastic, rubber, chemical fiber, chemical, pharmaceutical, daily chemical, chemical additives , metallurgical , power , light, food and other industries of material preheating, heating, cooling, distillation, distillation, concentration, material and the heat back Collection, tail gas treatment and other processes industrial.
The floating head type heat exchange equipment material can choose all kinds of stainless steel and other metal materials, the heat exchange tube adopts special seamless steel tube for heat exchanger, and the heat exchange area can be customized as required. The tube sheet and baffle are punched by nc drilling to ensure the accuracy of the hole. Tube plate and heat exchange tube welding joint adopts automatic argon arc welding, hydraulic expansion joint, quality safety and reliable, durable.
1) It will not afttect each other When there is a temperature difference between the heat exchange tube and the shell
2) The tube bundle can be taken out from the shell for cleaning.
