Question regarding blind plate force
Thread Content
I would like to ask everyone: For a free expansion joint installed on a vertical pipe like in the figure, can the force exerted by the blind plate at the top elbow section balance the weight of the pipeline itself (if their values are similar)?
In the free expansion joints installed on such vertical pipes, the force exerted by the blind plate in the upper elbow section usually cannot balance the weight of the pipeline itself. The blind plate force refers to the force resulting from changes in medium pressure and temperature at the expansion joint; it generates an upward torque, while the weight of the pipeline creates a downward torque. Therefore, if no other measures are taken to balance the blind plate force and the weight of the pipeline, the blind plate force will usually exceed the weight of the pipeline, requiring additional support structures to withstand this force. .
Is it not possible either if the self-weight of the pipeline is greater than the calculated blind plate force?
