Size issues of spire filters above 4MPa

Hello everyone, I’m seeking help regarding the detailed specifications and dimension tables for the metric series in the pointed-top filter standard HG/T21637-1991, specifically for pressures of 0.6, 1.0, and 2.5 MPa. There are no size and shape specifications for pressures above 4 MPa. What should everyone do when they encounter pressures above 4 MPa? I checked the SH/T3411-2017 version; it does contain instructions, but it removes the 1 graphic structure. Can I still use the dimensions from the SH/T3411-1999 version?

Theoretically, if there are no current standards, previous standards can be used as a reference!

With such high pressure, why not consider a Y-type filter? Can the pressure difference strength of conical filtration be guaranteed? For reference.
