Spades and Ring Spacers is a type of flanges used in many industries. The flanges are used to make the connection between two pipes better. There are different kinds of flanges such as the welding neck flange, orifice flange, swivel flange, blind flange, socket weld flange and the standard flanges. Each of them has a different purpose to serve and we manufacture all types of flanges. Rajveer Stainless And Alloys produces special types of flanges that are needed sometimes not to connect two pipes but to close a connection. The blind flanges are used for this purpose. The Flange Spacer Ring is a type of flange that has a spade on one side and the ring on the other side, parallel to each other.

Spades Ring Spacers Flanges

Reliable Manufacturer of Spacer Flange & Carbon Steel Flange Spacers

This type of construct makes it look like a spectacle and it is also called a spectacle flange. The Flange Spacer Rings allow fluid flow through the connection where the spade does not. So the flange could be used for dual purpose. The Pipe Flange Spacer is usually used in high maintenance systems where the pipes would have to be opened and closed regularly. The advantage of the Spade And Ring Spacer is that it does not need to be removed completely, the bolts could be loosened and the spade or ring could be rolled into position and be fitted to alter the function. Our Carbon Steel Flange Spacers are superior in quality and we offer custom made solutions to our customers. Please contact us for your requirements.

Difference between spades ring spacer flange for raised face and flat face

The spades ring spacer flanges are like the spectacle flanges but the two pieces are not connected together. They spade and ring come separately. They could be used with any raised face connection or with a flat face connection. Flat face connection has less space for connecting surface. The raised face allows for extra grip on the connection. Where welding is not possible or not necessary, the raised face allows bolt holes to be machined in. The spade is used when the line is closed and the ring is positioned when the line has to be open.
