Spectacle Blind Flange is generally applied to permanently separating pipe systems, or just to connect with each other. A Spectacle Blind is nothing but a steel plate cut into two discs of a certain thickness and these two discs are attached to each other by section of steel which is alike the nose piece of a pair of glasses. One of the discs tend to be a solid plate, and the other one a ring, whose inside diameter is same as that of a flange.

Spectacle Blind Flange be applied in systems, which regularly need to be separated from other installations. Generally, a Spectacle Blind Flange is mounted in the open position so that flow through the pipe is possible. If in case the Spectacle Blind a close position is rotated in circular mode, the pipe is blanked off and no flow is possible.

Maintenance on a pipesystem can be a reason to rotate the spectacle in the close position. This can take place through the hole, that is drilled in the connection piece. By making all the bolts loose, and removing them partially, the Spectacle Blind can be rotated. After replacing the gaskets with new ones, the bolts can be re-assembled and tightened again.

Spades and Ring Spacers are the same as Spectacle Blinds, however they both are not attached to each other. These Spades and Spacers are applied in systems where usually maintenance is not necessary or in applications including large pipe sizes. As per flange size and the Pressure Class, Spades can weigh hundreds of pounds of weight. In order to prevent needless weight to a flange connections, usually will be chosen not for a Spectacle Blind, except for 2 separate parts.

It is essential to use a thinner spacer, because a spacer with a standard thickness often can't be mounted between two flanges. As a rule of thumb the following formula can be used to calculate the thickness in millimeters :

  • Pressure multiply by diameter divided by 10
  • The highest pressure that the system can achieve
  • Diameter: the size of the spacer in inches
  • 8 x 12 / 10 thickness of spacer = 9.6 mm
