Not bad, thank you for sharing! But has the author carefully checked the corresponding standards?

* * Thank you for sharing. I didn’t pay much attention to the United States and Japan before, but when I encounter them later, I at least have some impressions.

I found that there are many flange sizes of 1.0mpa and 1.6mpa in the national standard. The outer diameter is slightly different. As the nominal pressure increases, the flange thickness and screw diameter should become larger? ? Am I wrong?

Why are there two commonly used nominal pressure levels of 2.5MPa and 4.0PMa in the national standard size?

Not bad, the workshop needs this as a reference
