As shown below: Found during calculation: When other conditions remain unchanged, the change with the gasket coefficient m is not significant. As the specific pressure y increases, the wall thickness also increases until it affects the bolt cross-sectional area. If the actual bolt cross-sectional area is smaller than the required bolt cross-sectional area, the verification fails.
This is the one I choose for all wrapping mats. However, there was a company audit that said asbestos cannot be used in highly hazardous media, so I changed it to a corrugated metal plate that conforms to graphite (similar to that), and the gasket was also changed to a toothed gasket: Q
Do you use corrugated metal plates when calculating input for all wound mat calculations?
Just be careful not to use winding mats that contain asbestos when there is a high degree of hazard or extreme hazard. The calculation is still the same: D

The first reply coded a lot of words, and then it said "please don't spam", and it was all white: L ； I couldn’t see the second reply even on my mobile phone. The review stated that "asbestos" pads cannot be used due to high media hazards. During calculations, the pads were replaced with composite flexible graphite corrugated metal, and the actual pads were changed to toothed pads. It feels like the only option is a spiral wound mat. If I choose a non-asbestos-filled spiral mat, I’m not sure what to choose~ From the formula, we can see that the required cross-sectional area of the bolt is only affected by the gasket, pressure, and stud material.
The APP is still being improved and will be ready soon. In fact, the impact of non-standard flange calculations on wrapped mats is quite large.
