Calculation issues for Q345B pipes in SW6
Thread Content
Help: The flange connections require Q345B, but in SW6, only Q345D, 16Mn, etc. are available. What do you all suggest I choose? :$
Please provide a solution. . . . . . . . . . . . . . . . . . . . . . . . . . . . :Q
Were the pipes, whether 6479 or 8163, classified into 5 grades: A, B, C, D, and E? I can’t remember; you can check it out. :sleepy: You can just choose 16Mn; you can then modify the details when preparing the calculation sheet, as the allowable stress values remain the same. It’s just that the specific chemical components differ slightly.
There is no difference between the allowable stress and yield strength of ABCD material
