Description
Technical Field
The utility model relates to an expansion joint technical field especially relates to a compound ceramic expansion joint.
Background
An expansion joint refers to a flexible element that effectively functions to compensate for axial deformation. For example, the expansion joint welded on the shell of the fixed tube-plate heat exchanger has large axial flexibility and easy deformation, can compensate the thermal expansion difference generated by the tube and the shell due to different wall temperatures, and reduces the axial load of the tube and the shell, thereby reducing the temperature difference stress of the tube, the tube plate and the shell and avoiding causing strength damage, instability damage and tube pull-out damage. The expansion joint has many kinds, and the common structures include wave, ring plate welding, clamping shell type and the like, wherein the wave expansion joint is most widely applied, and the ring plate welding expansion joint is only suitable for normal pressure or low pressure occasions. The existing expansion joint is not tight enough and easy to loosen during installation, and the existing expansion joint is not good enough in material and easy to corrode and damage.
