In the design of high-voltage equipment with large-diameter bolts, since strength calculations are not considered, what measures can be taken to ensure that such bolts do not fail? No answer was found.
Some materials seem to specify a reference load-bearing capacity, which may need to be converted to the operating temperature. First, the quality of the bolts must be satisfactory; second, the installation procedure must be proper, including subsequent inspections. Additionally, the materials used should be suitable for the working conditions, with little difference in physical properties compared to those of the equipment. These are the two key points
The limiting factor for flange bolts is stiffness, which prevents leaks from the flange, and there is a large safety margin in terms of strength.
Isn’t the required bolt cross-sectional area taken into account for strength?
As long as the cross-sectional area is sufficient, there are generally no problems. Of course, there are also corresponding requirements regarding the material, thread type, hardness, and so on; one can refer to the technical specifications for specialized fasteners
It’s no longer shown where; how is it possible not to show it?
