How to calculate connecting a DN20 fitting to a DN125 fitting
Thread Content
I encountered a situation where the design pressure is 8.0 MPa, the design temperature is 80 degrees, and the waste outlet has a diameter of DN125; on top of that, there is a connection pipe with a diameter of DN20. How should this be calculated? If DN125 is considered as the cylinder body, it does not meet the requirement of GB150, which stipulates that the inner diameter of the container must be at least 150 mm. However, it cannot be treated as a welded tee either, since the ratio of the two inner diameters is not greater than 0.5
Calculations can be carried out in accordance with \"Calculation of the Strength of Pressured Components in Shell and Tube Boilers\". :victory:
What standard is “Calculation of the Strength of Pressured Components in Shell and Tube Boilers”? Thank you!
