Thermal treatment displacement of spherical tanks
Thread Content
How is the displacement of a spherical tank during overall heat treatment calculated? I saw a formula in a reference book: “linear expansion coefficient of the spherical tank shell material * minus heat treatment temperature * bolt center distance * 0.5”. I didn’t understand it. 1. Why is “bolt center distance * 0.5” multiplied in? 2. Is the calculated result a radial displacement or?
This is the radial displacement, that is, the displacement in the radial direction; therefore, it needs to be multiplied by 0.5, which is half of the diameter.
Where did you see this formula in a reference book? ?
I’ve never worked with spherical tanks, but this formula is quite intuitive and easy to understand. The calculation result should be the displacement in the radial direction.
