Design and Performance Study of the Rubber Corrugated Pipe based on Flipped Mast

According to the special requirements of the rubber corrugated pipe for mast overturning, the structure and forming process of the rubber corrugated pipe are designed, and the required materials are selected and tested in this paper. The heat-shielding performance of the rubber corrugated pipe is simulated by using the thermodynamic module in ANSYS Workbench. The high temperature resistance, expansion and sealing test of model machine are performed. The test results show that the maximum compression height of the rubber corrugated pipe is 222 mm, the extension length is 1 230 mm, and the long-term temperature is 180 ℃. Under the compression, the insulation inside the corrugated pipe is reduced from 180 ℃ to 43.9 ℃ on the outer surface, and there is no leakage under the 0.05 MPa inflation pressure, meeting the design technical indicators. The analysis and design method, as well as the verification of the results, provide a reference for the design optimization requirements of the rubber corrugated pipe for the mast flipping.
