How to calculate pipe expansion joints?
Thread Content
Question: The settlement of the support frames for the tower and the reboiler differs, and since this issue cannot be resolved through civil engineering measures, it is suggested that expansion joints be added to the pipes connecting the tower and the reboiler. How should these expansion joints be calculated?
When the civil engineering requirements are specified, make them into a whole right from the start
I also think this falls within the scope of considerations for civil engineering; the foundation support for the two devices should be sufficient to handle it.
This falls under the scope of piping work. It needs to be submitted by the piping department to a stress analysis specialist for calculation.
The civil engineering team should determine the maximum allowable settlement difference; during piping, as many bends as possible should be used to increase the flexibility of the pipes, and then a stress analysis should be conducted to verify that the strength requirements are met. If stress analysis cannot be successfully carried out, then consider bellows expansion joints and similar solutions.
Unless it is a special material, expansion joints are generally not considered.
Expansion amount * total length * temperature change
