What type of expansion joint should be chosen?
Thread Content
Currently, we have added a section of 20# carbon steel pipe with a length of 34m, DN40, and dimensions of φ98*3. The lowest temperature in winter is -20 degrees, while the highest temperature of the fluid flowing through it is 100 degrees. Using the relevant formulas, the expansion amount for this pipe is calculated to be 50mm. So, what length expansion joint should be used? Where can this information be found in relevant standards? Thank you all
For such thin pipes, a few bends are sufficient; expansion joints are generally not needed.
It’s sufficient to use natural bends for compensation!
This should be posted in the pipeline stress analysis section! !
