A Spades and Ring Spacers is a very important part of pipes and tubes and has been in use for years. However, with time, it has undergone several changes. Today, Spades and Ring Spacers are available in different designs with improved functionality.
One can find Spades and Ring Spacers, socket-weld flanges, lap joint flanges, slip-on flanges, blind flanges, weld neck flanges, and more in the market. These Spades and Ring Spacers have their own specialty and make joining pipes a cakewalk with their smooth and hassle-free technique. For example, lap joint flanges are used where space is scarce and dismantling is required more often while Spades and Ring Spacers are utilized in process piping where piping is done under high pressure and high-temperature conditions.

Also, some pipe systems are quite long and cannot be installed and maintained without the help of Spades and Ring Spacers. So, Spades and Ring Spacers have become a part and parcel of the pipes/tubes system and since they are available in different dimensions and specifications, it is completely possible to meet the unique industrial requirements.
Spades and Ring Spacers Description
Ring spacers
Ring spacers are bored to the matching pipe ID and are the same thickness as the “single blind” that it replaces. When removing a “single blind”, either the flanges and associated piping must be pulled together to seal the line, or a “ring spacer” must be installed to fill the gap. Thick single blinds or rigid piping systems normally require ring spacers.
Spectacle Blind
A spec blind is a combination of a ring spacer and single blind. They are usually permanently installed in a piping system and rotated as needed.
