Composite three-way expansion joints in the cement industry
The compound three-way expansion joint in the cement industry refers to a flexible component that can effectively compensate for axial deformation. For example, the expansion joint welded on the fixed tube plate heat exchanger shell has high axial flexibility and is prone to deformation. It can compensate for the thermal expansion difference caused by different wall temperatures between the tube and shell, reduce their axial load, and thus reduce the temperature difference stress of the tube, tube plate, and shell, avoiding strength damage, instability damage, and tube pull-out damage. There are many types of expansion joints, including waveform, ring plate welding, and flange connection. Among them, professional expansion joints in the cement industry are most widely used, while ring plate welding expansion joints are only suitable for atmospheric or low-pressure situations.
