, GB150-1998 standard related to the definition of thickness (1) Calculated thickness is obtained by calculation according to the formula in each chapter. When necessary, it should also include the thickness required for other loads. (2) Design thickness d is the sum of calculated thickness and corrosion allowance C1. (3) Nominal thickness n is the design thickness d plus the negative deviation of steel thickness C1 rounded up to the standard specification of steel thickness. That is, the thickness marked on the drawing. (4) Effective thickness e is the nominal thickness n minus the corrosion allowance C2 and the negative deviation of steel thickness C1. (5) The relationship between various thicknesses is shown in the figure. (6) Blank thickness According to GB150-1998 Chapter 10 and the relationship diagram of various thicknesses: s= +C1+C2+Δ1(first design round-up value)+C3(machining thinning amount)+(second manufacturing round-up value).
