ASME B16.48 is a standard that specifies the dimensions, materials, pressure-temperature ratings, marking, testing and tolerances for operating line blanks in sizes NPS 1/2 through NPS 24 for installation between ASME B16.5 flanges in the 150, 300, 600, 900, 1500 and 2500 pressure classes.


Operating line blanks are devices that are used to isolate a section of a piping system for maintenance, testing or safety purposes. They can be either spectacle blinds, spades or spacers.


Spectacle blinds are metal discs that have one solid end and one open end connected by a web or tie bar. They can be rotated to either block or allow the flow of fluid through the pipe.


Spades are metal discs that have a solid end only. They are inserted between two flanges to block the flow of fluid through the pipe.


Spacers are metal discs that have an open end only. They are inserted between two flanges to allow the flow of fluid through the pipe.

What are the benefits of using ASME B16.48 spectacle blind flanges?




ASME B16.48 spectacle blind flanges are designed to provide a reliable and safe way of isolating a section of a piping system without having to disconnect or cut the pipe.


ASME B16.48 spectacle blind flanges are easy to install and operate as they only require a simple rotation of the disc to switch between open and closed positions.


ASME B16.48 spectacle blind flanges are durable and resistant to corrosion, erosion, abrasion and high temperatures as they are made of high-quality materials such as carbon steel, stainless steel, alloy steel or nickel alloy.


ASME B16.48 spectacle blind flanges are compatible with various types of gaskets such as metallic, non-metallic or spiral-wound gaskets depending on the service conditions and requirements.


ASME B16.48 spectacle blind flanges are available in different sizes, ratings, classes and configurations to suit different applications and specifications.

  • Q: How to choose the right size, rating, class and configuration of ASME B16.48 spectacle blind flanges?



  • A: The size, rating, class and configuration of ASME B16.48 spectacle blind flanges depend on the service conditions and requirements of the piping system such as the pipe size, pressure, temperature, fluid type, corrosion resistance, gasket type, etc. You can refer to the tables and charts provided in the standard or consult with an engineer or a manufacturer for guidance.



  • Q: How to install and operate ASME B16.48 spectacle blind flanges?



  • A: To install ASME B16.48 spectacle blind flanges, you need to follow these steps:



  • Align the spectacle blind flange with the pipe flanges and insert the appropriate gasket between them.



  • Secure the spectacle blind flange with bolts and nuts according to the specified torque values and tightening sequence.



  • Ensure that there is no leakage or damage to the spectacle blind flange or the gasket.



To operate ASME B16.48 spectacle blind flanges, you need to follow these steps:


  • Loosen the bolts and nuts slightly to allow the rotation of the spectacle blind flange.



  • Rotate the spectacle blind flange to either block or allow the flow of fluid through the pipe depending on your needs.
