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.
