What is the purpose of the solid plate and the open ring in a ASME B16.48 spectacle blind flange?

The solid plate acts as a barrier and completely blocks the flow when installed. The open ring in an ASME B16.48 spectacle blind flange allows visual confirmation of the flow status by creating a gap. This configuration is versatile for operations where temporary flow monitoring or isolation is required in a piping system.

Applicable Line Blanks Dimensional Standards


Dimensional Standards

  • In this standard Spectacle blinds are available only up to 24 Inches.
  • For Class 2500 spectacle blinds are upto 12 Inches.
  • No Class 400 spectacle blinds in this standard.
  • Facings available are Raised Face, Female Ring Joint and Male ring joint.

What is the role of pressure in the performance of a carbon steel spectacle blind flange?

The carbon steel spectacle blind flange can withstand and contain the pressure within the piping system when the blind plate is in place. This will ensure a reliable and leak proof seal. The pressure rating of the flange determines its maximum working pressure capacity. Selecting the appropriate pressure rating is essential to maintain the integrity and safety of the piping system.

How does the ASME B16.48 standard affect the design of figure 8 blind flange?

The ASME B16.48 standard provides guidelines for the design and dimensions of a figure 8 blind flange. It specifies the requirements for flange sizes, pressure ratings, facing types and materials used. The standard ensures that the flanges meet the necessary standards for compatibility, interchangeability and structural integrity.

Difference between ASME class 150 and ASME class 300 pressure rating in spectacle flanges

The difference between ASME Class 150 and 300 pressure ratings in spectacle flanges is in their maximum working pressure capacities. The higher-pressure rating of Class 300 flanges makes them suitable for higher pressure applications than Class 150 flanges.
