Abstract
The utility model relates to the technical field of pipe accessories, in particular to a high-temperature-resistant metallic corrugated expansion joint. The high-temperature-resistant metallic corrugated expansion joint comprises a connecting pipe I, a corrugated pipe and a connecting pipe II which are sequentially connected. The connecting pipe I is additionally communicated with diversion pipes. The diversion pipes are arranged below the corrugated pipe at intervals. A refractory castable layer is arranged at the lower parts of the connecting pipe I, a connecting pipe II and the diversion pipes. An anchoring part which extends downwards is arranged on the connecting pipe I, the connecting pipe II and the diversion pipes. The anchoring part is anchored with the refractory castable layer. Since the refractory castable layer is arranged, the high-temperature-resistant metallic corrugated expansion joint has the advantages that the structure is simple, the impact of high-temperature mediums to metallic materials can be isolated and the refractory castable layer is prevented from falling off under the situation of high-temperature deformation.
