Pressure resistance of stainless steel pipes

Recently, someone told me a formula for calculating the actual pressure-bearing capacity of stainless steel seamless pipes; please share your thoughts on this: Wall thickness/Outer diameter × 220 × 0.6 = Mpa. Using this formula to calculate the pressure capacity of a 25X2 stainless steel pipe: 2/25 × 220 × 0.6 = 10.56 Mpa

Should this pressure be the failure pressure or the maximum operating pressure?

The pressure calculated using the above formula is 105 kilograms, which is absolutely absurd! I think 10.5 kilograms is about right. Was a decimal point misplaced in the formula?

Experience is not reliable; specifically, it can be calculated using the cylinder wall thickness formula in GB150.

What is a reliable value in MPa for this specific conversion to pressure? !
