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."
