Blind Thickness
Blind Thickness Calculation.
Gasket I.D., d = inches
Pressure, p = psig
Corrosion allowance, c = inches
Blind Thickness, t = 0.000 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."
