Is the partition plate lower than the flange sealing surface?

I came across a drawing with the following markings; I’m asking where this information can be found in relevant standards or books Thank you, thanks for the answer provided by floor 13. GB/T151-2014 8.6.1 The sealing surface of the tube sheet partition shall be level with or slightly below the annular sealing surface of the tube sheet flange (with a control range of within 0.5 mm).
What kind of flange is this? Are there any special requirements?
According to which standard, then? Could you please explain it in detail? Thank you.
GB151 stipulates this in such a way
Please take another look at the revised post; I’m not referring to the width of the partition.
It seems no standard I’m aware of has similar provisions, but it’s been done a few times, and it was always specified by the project.
That regulation applies not only to width but also to depth; it concerns the specifications for the partition grooves. These are regulations set by our country, and since your design is of your own making, you should refer to the **standards**.
To ensure sealing, the partition is generally aligned with the flange sealing surface
Take a look at what the gasket grooves and gaskets on the tube sheet look like; looking at just one side doesn’t tell you much
To prioritize ensuring the sealing of the flange seal surface.
