3mm Thick 304 Stainless Steel Plate Welded Stainless Steel Pressure Tank, The Maximum Pressure？

Assumptions:

1, the weld quality is very good, good to the yield strength of the weld part is not lower than the yield strength of the surrounding material;

2, 3 mm stainless steel plate yield strength of 250 mpa

3, the actual thickness of stainless steel plate is 3 mm

4. The head is half round

5. The roundness of the cylinder is very good

Then: 6/500=P/250

Thus: P=6*250/500=3 mpa

3 mpa is the maximum pressure under ideal conditions, and when the safety factor is equal to 3,

The pressure tank is used at 1 mpa.

Note: A vessel is considered a pressure vessel when its diameter is greater than or equal to 200 mm and its operating pressure is greater than or equal to 1 mpa. At this time, it needs to be produced by a qualified manufacturer and passed the required inspection before it can be legally used.
