Dimension standard
ASME B16.48 
 

Flange spades and ring spacers, as separate products, are used when the rotation of a spectacle blind would be difficult due to space constraints. ASME B16.48 covers the dimensions and specifications of these isolation devices.

1. Spectacle blind
2. Flanges
3. Gaskets
4. Stud bolts
