Issue with expansion joints on the inlet and outlet pipes of the reboiler
Thread Content
I would like to ask everyone: Is it necessary to use expansion joints in a reboiler? Operating conditions: reboiler with forced circulation; maximum operating temperature of 160°C; steam at 1.2 MPa (which corresponds to a temperature of 191°C); flow rate of 1500–2500 m3/h. The inlet and outlet pipes of the reboiler have a diameter of DN600, the horizontal length of these pipes does not exceed 5 meters, and 316 stainless steel is used for construction. Is it necessary to use expansion joints in order to address the changes caused by temperature variations?
Horizontal expansion allows the reboiler to be made sliding. The problem of the oblong hole in the saddle has been resolved. For the vertical direction, this can be resolved by adjusting the height of the ear mount, or by using a spring. It is best not to use expansion joints, unless the pressure is very low.
Well, thank you. That’s how we think it should be; vertical support is provided by spring supports. But the mechanical engineering department of the design institute said it’s necessary to use it
