General notes..
1.Dimensions are in millimeters unless otherwise indicated.
2.Spade Handles shall be solid with NO openings.
3.Ring Spacer Handles shall have a single through indicator hole located near the end of the handle. The hole diameter shall not be less than 12 mm.
4.Wt = Thickness of the handle should be 6 mm minimum, or equal to Thickness (t) if less than 6 mm.
5.Spades and Ring Spacers should be made from a plate or forging specification, approved for use by ASME B31.3, of essentially the same chemical composition as the mating flanges and piping involved.
6.Spades and Ring Spacers ASME B16.48 may be used for installation between ASME B16.5 flanges
7.Depending on a customer specification, some dimensions can be different from what on this page is defined.
