A Spectacle Blind is a steel plate cut into 2 discs of a certain thickness. Spectacle Blinds are normally applied to permanently separating pipe systems, or just to connect with each other.
The 2 discs are attached to each other by a section of steel same as the nosepiece of a pair of glasses. One disc is a solid plate, and the other disc is a ring, so the inside diameter is equal to that of a flange.
Spectacle Blinds are applied in systems, which regularly need to be separated from other installations. Normally, a Spectacle Blind is Fixed in the “open” position so that flow through the pipe is possible. If the Spectacle Blind in the “close” position is rotated, the pipe is empty and no flow is possible.
Spades and Ring Spacers
Spades and Ring Spacers are the same as Spectacle Blinds, except that both are not attached to each other.
Spade and Spacer are applied in systems where maintenance is often not required, or in applications with big pipe sizes. Depending on the flange size and also the Pressure Class, Spades may weigh hundreds of pounds. To prevent unnecessary weight to flange connections typically are going to be chosen not for a Spectacle Blind, but for two separate parts.
Maintenance on a pipe system may be a reason to temporarily replace a Ring Spacer for a Spade. By loosening all bolts, and half the bolts are temporarily removed, and the Spade or Spacer may be placed. After replacing the gaskets (always new gaskets are to recommend), the bolts can be re-assembled and tightened.
A small problem is that we normally can not see, or a Spade or a Spacer Fixed between the flanges. Therefore the handles are often specially marked, or both have a different design; a client often provides its own specification.
What should never be lacking is, that in the handle, the diameter and the Pressure Class of a Spade or Spacer are engraved; this applies also to the Spectacle Blind.
The sealing surfaces of a Spectacle Blind, Spade, or Ring Spacer are generally conducted in accordance with the Face Finish from the flange. The diameter always is a little larger than the Raised Face of a flange; by a correct assembly, the bolts are just not touched by the Blind or Spacer.
The diameter of them is depending on the flange size and the thickness from the Pressure Class of a flange.
ASME B16.48 covers pressure-temperature ratings, materials, dimensions, dimensional tolerances, marking, and testing for operating line blanks in sizes NPS 1/2 – NPS 24 for installation between ASME B16.5 flanges in the 150, 300, 600, 900, 1500, and 2500 Pressure Classes.
Spectacle Blinds, 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.
