What is a floating head heat exchanger? What is the appearance of the floating head heat exchanger? What are the products of floating head heat exchangers? What are its characteristics? With these questions, let's learn together.

The tubesheet at both ends of the floating head type heat exchanger is not connected with the shell at the end, but the end is called the floating head. When the heat dissipating body is heated, the tube bundle and the floating head can be freely expanded along the axial direction, so that the temperature difference stress is completely eliminated.

The floating head end structure comprises a cylinder, an outer head cover side flange, a floating head tube plate, a hook ring, a floating head cover, an outer head cover, a wire hole, a steel ring, etc.

The utility model is characterized in that a concave or trapezoidal sealing surface is arranged on the inner side of the flange on the side of the outer head cover, a hole is drilled near the sealing surface, and a plurality of screws are arranged uniformly, a hook ring and related parts are cancelled at the floating head, and the sealing groove of the floating head tube plate is an original concave groove, and another one is opened at the same end face to take the center of the tube plate as a circle, with a slightly larger radius. The ladder groove of the outer diameter of the tube bundle is connected with the ladder groove only, but not with the groove.
