All dimensions are in millimeters unless otherwise indicated.
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 
General notes:
 

 

 

 

 

 

 

 
? D = Hole size (where required) should be the same as the flange bolt hole. In practice, these dimensions have been rounded round off upwards.
 

 

 

 

 

 

 

 
? T1 = Thickness Carbon Steel.
 

 

 

 

 

 

 

 
? T2 = Thickness Stainless Steel.
 

 

 

 

 

 

 

 
? W = Thickness of the web (or tie bar) should be 0.25 inch (6 mm) minimum, or equal to T1 and T2 if less than 0.25 inch (6 mm).
 

 

 

 

 

 

 

 
? Spectacle Blinds should be made from a plate or forging specification, approved for use by ASME B31.3, of essentially the same chemical composition as the mating flanges
 

 

 

 

 

 

 

 
   and piping involved.
 

 

 

 

 

 

 

 
? Depending on a customer specification, the dimensions can be different from what on this page is defined.
