What are calculated thickness, design thickness, nominal thickness, and effective thickness? ...................................................................... Answer: Calculated thickness: refers to the thickness obtained through relevant formulas; if necessary, the thickness required to accommodate other loads must also be taken into account, excluding any additional thickness amounts. Design thickness: refers to the sum of the calculated thickness and the corrosion margin ； Nominal thickness: It is the design thickness plus the negative deviation in steel thickness, rounded up to the standard thickness specified for the steel; this is the thickness indicated on the drawings. For container shells, the nominal thickness must under no circumstances be less than the sum of the minimum thickness and the corrosion allowance ； Effective thickness: refers to the nominal thickness minus the corrosion allowance and the negative deviation of the steel thickness.
Calculated thickness: refers to the thickness obtained by applying relevant formulas; where necessary, the thickness required for other loads must also be taken into account, excluding any additional thickness amounts.

The calculated thickness is the minimum wall thickness determined based on pressure; the effective thickness is the sum of the calculated thickness and the corrosion allowance, while the nominal thickness is the design thickness plus the thickness deviation. The design thickness is the value obtained by rounding the effective thickness to a standard plate thickness
Calculated thickness: The thickness obtained through calculation using relevant formulas, with the influence of other loads on the thickness taken into account if necessary. Design thickness: The sum of the calculated thickness and the corrosion allowance. Nominal thickness: The design thickness, plus the negative deviation of the actual thickness, rounded to the thickness specified by the steel standards, is the thickness indicated on the drawings. Effective thickness: Nominal thickness minus corrosion allowance and negative steel deviation.
Calculated thickness refers to the thickness obtained through formula calculation; if necessary, the thickness required for other loads should also be included, excluding any additional thickness amounts. The design thickness refers to the sum of the calculated thickness and the corrosion allowance. The nominal thickness is the design thickness plus the negative deviation of the steel thickness, rounded up to the standard specification of the steel, which is the thickness indicated in the drawing. Under any circumstances, the nominal thickness of the container shell shall not be less than the sum of the minimum thickness and the corrosion allowance ； Effective thickness refers to the nominal thickness minus the thickness allowance.

1. Calculated thickness refers to the thickness obtained through formula calculation; if necessary, the thickness required for other loads should also be taken into account, excluding any additional thickness amounts； 2. The design thickness refers to the sum of the calculated thickness and the corrosion allowance ； 3. The nominal thickness is the design thickness plus the negative deviation of the steel thickness, rounded up to the standard specification thickness of the steel, that is, the thickness indicated in the drawing. Under any circumstances, the nominal thickness of the container shell shall not be less than the sum of the minimum thickness and the corrosion allowance ； 4. Effective thickness refers to the nominal thickness minus the thickness allowance.
1. Calculate the thickness: The thickness value obtained through the calculation formula represents, in theory, the minimum thickness permitted by the device； 2. Design thickness: Calculated thickness + corrosion margin ； 3. Nominal thickness: Designed thickness + rounded value after applying the negative thickness deviation ； 4. Effective thickness: Nominal thickness minus the negative thickness deviation!
