The utility model belongs to the technical field of high-temperature device and pipe heat preservation, and particularly relates to a radial heat expansion heat preservation device. The radial heat expansion heat preservation device comprises a protective layer, the protective layer is set to be corrugated plates, a connecting band is tied to the peripheries of the corrugated plates, the two ends of the connecting band are connected through a spring tension frame, the connecting band is connected with the corrugated plates through J-shaped clamps, the J-shaped clamps are fastened on the corrugated plates, an S-shaped clamp is arranged at the lap joint position of the vertically-adjacent corrugated plates, and the two ends of the S-shaped clamp are fastened to the corrugated plates. According to the radial heat expansion heat preservation device, the S-shaped clamp same as the corrugated plates in mode is adopted for the vertical lap joint position of the corrugated plates to fixedly connect the upper portion with the lower portion of the protective layer, after overall heat preservation is carried out, when the steel band is tied to a vertical type device and a vertical pipe, the steel band is fixed through the J-shaped clamps with corrugation on one sides to enable the steel band to be attached to the device or the pipe, the connecting positions between the outer protective layer and the steel band are connected through the spring tension frame for fixing, a certain stretching range is achieved, and it is guaranteed that stress on each circle of the steel band is even.
