Why is the tower shell circular?
Thread Content
Let’s discuss why cylinders are generally round Let’s see if anyone has noticed this problem
Circles can reduce welds, prevent leakage and corrosion, and have a larger area for the same perimeter
Reply to 2# floweronsun: What you say makes sense. What about considering it from a mechanical perspective?
I work in the field of manufacturing processes, and I don’t have much knowledge about equipment. I believe the main advantage of using a circular shape is that the stress distribution is even throughout, unlike square or other shapes, which have stress concentration points that can lead to fatigue damage
In my opinion, a circular cylinder should experience the best stress distribution and require the thinnest wall thickness
In my opinion, the reason for making it round is mainly to consider aspects related to manufacturing techniques as well as stress analysis. According to TCED41002-2000, the tolerance for the verticality of tower installation is one thousandth of the tower height, with a maximum value of 30 mm. It can be seen that uniform stress distribution is required in terms of stress analysis. At the same time, vessels with circular cylinders are generally pressure vessels, and welding specifications also apply to them. Welded joints include butt joints, lap joints, and corner joints.
