&APage &PNote:

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."
