How to determine the nominal thickness of high-voltage equipment
Thread Content
By how much is the nominal thickness of a horizontal tank with a resolution of around 20MP greater than the calculated thickness? For example, if the calculated thickness is 40 mm, what is the typical value for the nominal thickness?
Now, many steel plate manufacturers in China are capable of producing steel plates with odd thicknesses, so there’s no need to use 2mm as the interval anymore.
In situations like this, if you’re not sure whether it will be cold forming or hot forming, nor the degree of shock absorption during forming, it’s best to roughly estimate the material thickness so that it won’t cause the allowable stress of the material to change significantly. Indicate on the drawing that the minimum thickness after forming should be no less than the designed thickness. Moreover, the drawing must specify that the material thickness used must ensure that the minimum thickness of the cylinder or head after molding is greater than or equal to the requirements specified in the drawing, and that the material thickness is determined by the manufacturing process. In this manufacturing process, the material thickness is selected to ensure the minimum thickness required by the drawings. You don’t have to worry then.
