Properties of Spectacle Blind Flanges

A spectacle blind flange, also known as a figure-8 blind flange, is a specific type of flange used in piping systems. It is designed to provide a positive shut-off when the line needs to be isolated or blocked off.

Here are some key properties and features of spectacle blind flanges:

  • Design: Spectacle blind flanges consist of two metal discs connected by a central section that resembles the shape of a figure-8 or a pair of spectacles. The metal discs can be rotated independently to either block or allow the flow of fluid through the pipeline.
  • Dual Functionality: The spectacle blind flange can serve as both a blind flange and a spacer flange. By rotating the discs, it can either block the flow completely (blind function) or allow flow through one side while the other side remains closed (spacer function).
  • Positive Isolation: When the spectacle blind flange is in the closed position, it provides a positive seal, effectively isolating the section of the pipeline from the rest of the system. This allows maintenance, repair, or replacement of equipment downstream without shutting down the entire system.
  • Durability: Spectacle blind flanges are typically made from durable and corrosion-resistant materials such as stainless steel, carbon steel, or alloy steel. The material choice depends on the specific application and the compatibility with the process fluid.
  • Pressure and Temperature Rating: Spectacle blind flanges are designed to withstand high-pressure and high-temperature applications, similar to other flange types. The pressure and temperature ratings of the spectacle blind flanges should match the requirements of the pipeline system.
  • Size and Dimensions: Spectacle blind flanges are available in various sizes and dimensions to accommodate different pipe sizes and pressure ratings. The dimensions follow standard specifications such as  ANSI B 16.48 Spectacle Blind Flanges.
  • Flange Face: The spectacle blind flange face can have different configurations, such as raised face (RF), flat face (FF), or ring joint (RTJ). The flange face type is chosen based on the specific application and the requirements for sealing and gasket installation.
  • Gasket and Bolting: Spectacle blind flanges require appropriate gaskets and bolting to ensure a secure and leak-free connection. The choice of gasket material and bolting specifications depends on the operating conditions and the compatibility with the process fluid.
  • Alignment and Installation: During installation, the spectacle blind flange discs should be aligned properly to ensure smooth operation and effective sealing. Care should be taken to follow the manufacturer’s guidelines and recommendations for correct installation procedures.
  • Standards and Codes: Spectacle blind flanges are designed and manufactured according to various industry standards and codes, such as ASME B16.48 Spectacle Blind Flanges. Compliance with these standards ensures the flanges meet the required quality and safety standards.
