Stuffing box heat exchanger

☆ Structural features: ● The stuffing box sealing structure is adopted, and the tube bundle can freely expand and contract in the axial direction of the shell, without causing thermal stress due to the difference in thermal deformation between the shell wall and the tube wall. ● Compared with floating head heat exchanger, it is simple in structure, convenient in processing and manufacturing, material saving, affordable in cost, flexible in tube bundle extraction, cleaning and maintenance in and between tubes, and easy to operate; ☆ Application field: It is widely used for heat exchange of liquid and liquid and cooling of gas. Typical applications are as intercoolers and aftercoolers in hydraulic systems, large automobile manufacturing, shipbuilding and other industries.
