Problems with the flange cover

How can I determine the dimensions of the cover for that tube box? ? I checked HG20601-97, but the data I got shows that it doesn’t match the original flange
JB/T4703-2000 is the standard for equipment flanges, while HG20601-97 is the standard for pipe flange covers; these two standards cannot be used together. There is no standard in this case, so a custom flange cover must be designed based on the dimensions of the equipment flange
What was said upstairs is correct – the two standard flanges are indeed not the same type of flange. In the owner’s case, the flanges are usually designed by oneself
To use that standard flange, this standard flange cover must be chosen in order to ensure a proper match between the flange and the flange cover.
The cover plate needs to be designed, as there is no matching flange cover for the equipment flange.
The device can also use HG20601
The flange cover can be made to non-standard specifications; just do the calculations
6# For the demons, it’s just that indeed, the design of the flange covers on our equipment is also based on HG20601
