NOTES :
1. This standard applies only for Tapped Orifice Flanges.
2. Dimensions shown are minimum required. When possible they should be increased.
3. When bends are used instead of fittings to change direction, dimension of lines shall be to tangent line of bend.
4. All tabulated dimensions are based on the joint A.G.A – ASME fluid committee report 3 of April 1985, and maximum orifice diameter ratio (d/D) of 0.70. Dimensions shown are to the center or face of orifice plate.
