Blind Thickness Calculation.

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."




Gasket I.D.,       d=                 inches
Pressure,          p=                 psig
Corrosion allowance, c =              inches

Blind Thickness,     t=        0.000 inches
