Tube-sheet pull-out force conversion
Thread Content
Dear experts, the results of the test report show that the pull-off force is 7.648 kN. How do I convert this value to MPa? The specifications of the heat exchange tube are Φ19.05×0.381 mm, thank you!
Is it necessary to know the clamping length, or is this value fixed?
Is there a flange groove? What is the thickness of the tube sheet? The pulling force/welding area is in MPa: 7.648/(19.05π×tube sheet thickness)
Should it be divided by the expansion joint area or the cross-sectional area of the heat exchange tube?
Expansion area; tube cross-sectional area is used to test the strength of the tube
