Blind Thickness Calculation.
Gasket I.D., d = 16 inchesPressure, p = 150 psigCorrosion allowance, c = 0 inches
Blind Thickness, t = 0.627 inches
Note:
1. Blind thickness is based on ANSI B31.3, equation 15.
2. Blind will be installed between ANSI B16.5 flanges.
3. Thickness is based on the use of carbon steel having a tensile strength of 55,000 psi and a yield strength of 18,300 psi.
4. Gasket I.D. can be obtained from the table under work sheet tab titled "Gasket I.D."
