Spacer flange is machined from a single piece of metal that is cut to match the pipe size, fit between two pipe flanges and requires an additional gasket when it is installed.
Also, the bolts will need to be lengthened depending on what piping class and size blind is used. The thickness of the spectacle blind is specified based on the line pressure and pipe size
Spade Flange
Spade Flange Spacers are basically the same as Spectacle Blinds, except that both are not attached to each other.
Spade Flange be applied in systems where maintenance is often not necessary, or in applications with large pipe sizes.
Spade Flange, 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.
