Spade Ring Blind Flange

Spade Ring Blind Flange

Ring spacer looks like a steel ring with a handle plate.The spacer has a same usage with the ring part of a spectacle blind flange.The spacer ring blind flange has a same outer diameter with the spade ring blind fflange.Spacer flange is machined from a single piece of metal that is cut to match the pipe size,fit between two pipe flanges and requires an additional gasket when it is installed.

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.To change it from open to closed,only half the bolts need to be removed and the spade or spacer is swapped over. The removed bolts are then installed and tightened.The handle protrudes from the pipe and provides an indicator of whether a spade or spacer is installed.

For smaller spades and spacers it is common for the spacer to have a hole in the handle and the spade or paddle blind to have no hole.For larger sizes spectacle blinds can be very bulky and occupy a lot of space so spades and spacers are preferred. Also,the bolts will need to be lengthened depending on what piping class and size blind is used.The thickness of the spectacle blind is specified based on the line pressure and pipe size.
