Spade and Spacers are kinds of flanges used as Line Blinds. Jointly they perform the same function as a Spectacle Blind as essentially a simplistic valve. The Spade or Spacer is fitted in the line between two flanges and is bolted in place. The Spacer is used when the line is required open and the Paddle Blind or Spade is installed when the line is required blocked or closed.
Spade is very similar with Blind flange but with a handle for easy operation.
It is used usually for maintenance when it is required to isolate a section of pipe or isolate a device. Because this is a semi-permanent isolation it is very safe and safety is often the mentality behind the use of a Spade and Spacer in maintenance operations. Compared to a valve they are cheap and robust.
ASME B16.48 is a standard developed by the American Society of Mechanical Engineers (ASME) that specifically addresses the design, materials, dimensions, tolerances, and marking of steel line blanks (also known as paddle blanks or spades) and spectacle blinds. These components are primarily used in piping systems for the purpose of isolation or control of flow.
This Standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing for operational 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.
