Is there a specified minimum distance between Class D welds?

For example, is there any specification regarding the minimum distance between the fillet weld between the manhole and the head of a carbon steel vessel, and the fillet weld between the flange and the head?
I also want to ask about this question; does anyone know it?
Firstly, if the distance is too short, joint reinforcement will be necessary for hole reinforcement; when the distance is too small, the mutual influence of the heat-affected zones must be taken into account.
GB 150 was not seen, but clause 10.2.4 of GB 50341 requires that the distance between the edges of the two openings (in the case where there are no reinforcement plates) be no less than 75 mm; this can be used as a reference
I remember that during exams before, it was 1 meter
It must be not less than 3 times the wall thickness and not less than 100. It can be seen that for some companies, it is not less than 3 times the wall thickness and not less than 50.
The answer should be the distance determined by combining the distances from the 3rd floor and the 6th floor, with the larger value being taken.
In the old Rong regulations from the 1990s, it was stipulated that the distance between two welds could not be less than 50 mm; this requirement was later removed
The mesopore (stirring pore) is located in the middle of the flange, which serves as a reinforcement element.
